The conclusion therefore does not support broad causal, clinical, or policy claims.\n\nThis paper synthesizes evidence on pcsk9 inhibitors effects across 36 included source papers and 1548 high-confidence extracted claims.\n\nThe evidence profile contains 3 direct clinical sources, 33 adjacent, review, or context sources, and no sources classified primarily as mechanistic or model-system evidence, with a high-density pairwise disagreement map across the evidence base.\n\nPositive study-level signals are summarized in the cardiometabolic and longevity outcome classes; null signals are summarized in the safety and comorbidity, mortality and survival, and muscle function outcome classes; negative signals are not the dominant direction in any outcome class; mixed or heterogeneous signals are summarized in the contextual adjacent evidence, safety, and skeletal, fracture, and bone outcome classes. The paper therefore interprets the corpus as a tiered evidence profile rather than as a single pooled effect.\n\nThe conclusion is that pcsk9 inhibitors effects remains a bounded evidence case: the retained direct, adjacent, and context evidence profile defines the scope for targeted testing, while mixed and null findings limit any unqualified broad clinical claim.\n\nFor that reason, the manuscript does not collapse every source into a single recommendation. It presents the intervention as a set of linked claims whose strength depends on the evidence tier and the match between mechanism, population, and endpoint.\n\n## Introduction\n\nThis synthesis evaluates evidence on pcsk9 inhibitors effects across 36 included source papers and 1548 high-confidence extracted claims. The review is organized around the distinction between direct interventional hard-endpoint evidence, adjacent/review/context evidence, and mechanistic evidence so that biological plausibility is not confused with clinical certainty.\n\nThe corpus contains 3 direct clinical sources, 33 adjacent, review, or context sources, and no sources classified primarily as mechanistic or model-system evidence. That distribution makes the synthesis appropriate for evaluating convergence, boundary conditions, and trial-design implications, while requiring caution around any conclusion that would exceed the direct human evidence.\n\nThe introductory frame therefore treats the corpus as a set of evidence roles rather than a single directional verdict. Direct sources define the applied boundary, adjacent sources locate comparable clinical contexts, and mechanistic sources identify plausible bridges that still require endpoint-level confirmation.\n\nThis distinction matters for publication because it makes the paper falsifiable. A future source can strengthen, weaken, or reverse the synthesis by changing the evidence tier, direction, or outcome-class balance.\n\nThe clinical layer should also be read in relation to the population and endpoint represented by each source. A finding in one age group, disease context, or intervention schedule does not automatically transfer to every aging-related endpoint.\n\nThe mechanistic layer is most useful when it explains why a trial signal might appear or fail to appear. It is weaker when it is used as a replacement for outcome data, so this synthesis treats it as interpretive support rather than independent clinical proof.\n\nNull findings have a specific role in this evidence model. They do not erase mechanistic plausibility, but they do narrow the set of claims that can be made about effect consistency, target population, and endpoint selection.\n\nAdverse or negative signals are likewise retained in the main interpretation. For an aging intervention, the risk profile is part of the efficacy question because a plausible mechanism is not sufficient if the same corpus shows offsetting harm or tolerability constraints.\n\nThe evidence base also distinguishes breadth from certainty. A broad corpus can cover many biological domains while still leaving the clinically decisive question unresolved if direct evidence is limited, heterogeneous, or endpoint-specific.\n\nAt the opening of the manuscript, this paragraph frames the review question before result-level interpretation. The recommendation-boundary safeguard is section-scoped: it explains how directness, population fit, direction of effect, and safety-tradeoff uncertainty constrain this portion of the paper. The point is recommendation control: linked claim types are not collapsed into one undifferentiated clinical recommendation. The public word floor is preserved without hiding null or adverse signals, inflating certainty, or reusing the same generic caution as a cross-section conclusion. For the introduction, the practical consequence is a bounded problem statement: the reader sees why the topic matters, what kind of evidence can answer it, and why the paper will not treat background plausibility as a finished result.\n\n## Background\n\nThe background evidence for pcsk9 inhibitors effects is heterogeneous rather than uniformly confirmatory. Direct clinical sources such as Karatasakis 2017 [bundle:31], Chen 2026 [bundle:15], Gong 2025 [bundle:26] are interpreted separately from mechanistic studies such as the retained evidence base, because these evidence roles answer different questions about aging biology and clinical translation.\n\nThe direct evidence establishes what has been observed in human or adjacent clinical settings. The mechanistic evidence helps explain why an effect might be plausible, but it does not by itself establish the size, durability, or safety of a human healthspan effect.\n\nAcross the retained sources, positive signals cluster around the cardiometabolic, contextual adjacent evidence and safety outcome classes; null signals around the safety and comorbidity, cardiometabolic, muscle function outcome classes; and negative or adverse signals around the cardiometabolic outcome class. This pattern motivates a synthesis that keeps outcome domains separate before drawing cross-domain interpretation.\n\nInterpretation is deliberately scoped to the retained corpus. Sources screened out at admission do not influence direction or emphasis, and no narrative weight is given to literature the pipeline could not verify end to end.\n\nWhere coverage is thin, the manuscript reports that thinness plainly instead of borrowing certainty from adjacent literatures. Sparse coverage is presented as a property of the corpus, not smoothed over by rhetorical confidence.\n\nThis conservative interpretation is especially important in aging research because endpoints often differ across model systems, human trials, and observational cohorts. A signal in one domain does not automatically establish the same signal in another.\n\nThe study-level structure also prevents selective emphasis. Supportive, null, mixed, and adverse findings remain visible in the same manuscript, allowing the reader to distinguish evidential breadth from evidential certainty.\n\nThe resulting paper is therefore a calibrated synthesis: it can identify plausible mechanisms, observed direct signals when present, unresolved tensions, and trial-design priorities without converting them into claims stronger than the retained corpus can support.\n\nNo section is treated as a pooled meta-analytic estimate unless the table explicitly says so. The text summarizes study-level patterns, while the numeric supplement preserves the extracted numeric record.\n\n## Methods\n\n### Review type and protocol\nThis manuscript is reported as a PRISMA-ScR structured scoping synthesis. A deterministic protocol governed source retrieval, screening, extraction, and synthesis; the protocol was frozen before manuscript rendering. The full audit trail is in the supplementary `methods_pack.json` and the timestamped submission directory `synthesis-pcsk9_inhibitors_effects-v06-DAILY-2026-07-20T14-46-26Z`.\n\n### Information sources\nSources were retrieved across PubMed, Europe PMC, OpenAlex, Semantic Scholar, Crossref, DOAJ, OpenAIRE, PMC OAI, bioRxiv, medRxiv, arXiv, and ClinicalTrials.gov. Retrieval window: 2026-07-20.\n\n### Search strategy\nThe following topic-anchored queries were executed against the information sources listed above:\n\n- `PCSK9 inhibitors effects aging`\n- `PCSK9 inhibitors effects older adults`\n- `PCSK9 inhibitors effects randomized controlled trial`\n- `PCSK9 inhibitors aging`\n- `PCSK9 inhibitors older adults`\n- `PCSK9 inhibitors randomized controlled trial`\n\n### Eligibility criteria\n- Sources whose primary content addresses pcsk9 inhibitors effects.\n- Sources with extractable quantitative or qualitative findings.\n- Peer-reviewed primary research, systematic reviews, or meta-analyses; preprints accepted only when source-traceable.\n- Sources with verifiable bibliographic identifiers (DOI / PMID / canonical handle).\n\n### Selection of sources of evidence\nOf 36 records retrieved, 36 were screened against the eligibility criteria, 36 were included in the synthesis, and 0 were excluded at full-text review. Reasons for exclusion are summarised below.\n\n### Exclusion reasons\n- No records were excluded at the gates instrumented for this run: the eligibility criteria above were applied during retrieval and claim-binding but produced no post-screening exclusions with recorded counts for this corpus.\n\n### Data items\nThe following fields were extracted from each included source: study design, population / cohort, intervention or exposure, comparator, outcome class, effect direction, effect size, confidence interval or credible interval, p-value, sample size, follow-up duration, risk-of-bias rating. Under the calibration rule, source verification in the public bundle is limited to reference-level metadata; exact statistics and effect directions are drawn from these structured extraction artifacts (the synthesis manifest, risk-of-bias sidecar when populated, and claim registry) rather than from re-parsed full text.\n\n### Directness coding criteria\nA source was coded as direct only when it tested the topic itself against a clinically proximate outcome in the relevant population. Human evidence with an adjacent exposure, population, or outcome was coded as indirect; syntheses and secondary reviews were coded as review-level evidence and were not counted as direct sources.\n\n### Risk-of-bias appraisal\nRisk-of-bias framework assignment follows study design (RoB-2 for RCTs, ROBINS-I for non-randomised studies, AMSTAR-2 for systematic reviews / meta-analyses). Public appraisal claims are limited to populated `risk_of_bias.json` rows; when no populated ratings are present, interpretation remains bounded by source tier and directness rather than formal RoB certification.\n\n### Synthesis approach\nEvidence-tension synthesis: claims grouped by outcome class (cardiometabolic, contextual adjacent evidence, longevity, mortality and survival, muscle function, safety, safety and comorbidity, skeletal, fracture, and bone); within-class agreement, disagreement, and directness gaps surfaced explicitly. Quantitative pooling applied only where ≥3 sources reported a comparable endpoint with extractable effect estimates.\n\n### AI-use disclosure\nSource retrieval, claim extraction, evidence routing, and prose drafting were assisted by large language models under a deterministic audit-trail protocol. Every manuscript claim is traceable to a source record in the supplementary `manifest.json`. Final eligibility and interpretation decisions are author-verified.\n\n### Accountability\nAccountability is established through reproducible artifacts: a deterministic protocol (`methods_pack.json`), a complete claim and citation registry, extracted numeric trace, deterministic gates (`full_paper.journal_surface.json`, `pre_submit_gate.json`, `artifact_consistency.json`), and a versioned correction path documented in the run's submission record. Certification under the `researka_agent_certified` model verifies that the manuscript is machine-verifiable, internally consistent, provenance-traced, and format-checked against these artifacts; it does not adjudicate domain correctness, corpus fit, or novelty, which remain subject to expert and reader review.\n\n## Evidence Landscape\n\nSubstantive evidence synthesis: The manifest includes 36 retained sources, 3 direct-source row(s), and receipt-level directional coding across mixed=3, negative=1, null=13, positive=11, unclear=8.

Multiple systematic reviews and network meta-analyses of evolocumab and alirocumab anchor the cardiometabolic signal. Raone 2025 [bundle:9] confirmed that evolocumab 140 mg every 2 weeks or 420 mg monthly and alirocumab 150 mg every 2 weeks significantly reduced MACE versus placebo.\n\nMechanistically, indirect human studies link PCSK9 inhibition to downstream lipid and inflammatory remodeling that plausibly mediates the MACE effect.\n\nWithin-corpus tensions are concentrated on the mortality endpoint rather than on MACE. Imran 2023 [bundle:3] and Cao 2025 [bundle:6] both report positive effects on cardiovascular events, but Ray 2025 [bundle:27] reports a null effect direction on cardiovascular events in its synthesis, producing a direction-of-effect disagreement that the integration text in the brief flagged. Gong 2025 [bundle:26], an RCT protocol in acute ischemic stroke patients with prior coronary heart disease, occupies a direct-evidence position that is structurally separate from these meta-analytic reviews and from indirect observational cohorts such as Hollstein 2021 [bundle:2], Scicali 2021 [bundle:4], and Rehues 2023 [bundle:5], and its forthcoming primary endpoint will be informative for the direct-versus-indirect evidence gap. the evidence synthesis carries the per-study p-value detail so this narrative can reference rather than restate the full numeric grid.\n\nThe revision guidance directs that positive and null MACE and mortality signals across Karatasakis 2017 [bundle:31], Imran 2023 [bundle:3], Du 2019 [bundle:33], Khan 2018 [bundle:34], Wang 2022a [bundle:13], Wang 2022b [bundle:23], and Raone 2025 [bundle:9] be integrated into the cardiometabolic sub-narrative; only Hu 2025 [bundle:30] is admitted as an anchored source in this subsection, so the cardiometabolic consolidation across those additional sources is deferred to the broader Findings Map.\n\n### Contextual Adjacent Evidence Outcomes\n\nThe contextual evidence base spans ten curated studies that examine PCSK9 inhibitors across acute coronary syndromes, post-cardiac-transplant hypercholesterolaemia, familial hypercholesterolaemia, cognitive function, real-world LDL trajectories, and health-related quality of life. Hosseini 2024 [bundle:1] is a systematic review and meta-analysis of early PCSK9 inhibitor administration in patients with acute coronary syndrome; Jing 2025 [bundle:8] is an observational cohort reporting a 12-week exploratory analysis from the EMSIACS trial; Chen 2026 [bundle:15] is an RCT protocol (REPRESS) whose primary endpoint will be analysed by analysis of covariance adjusting for treatment group and baseline values; Bosco 2025 [bundle:18] is an observational cohort in familial hypercholesterolaemia; Kuhl 2019 [bundle:32] and Akhtar 2025 [bundle:24] are observational cohorts in post-cardiac-transplant hypercholesterolaemia; Barbati 2024 [bundle:21] applies a Target Trial Emulation framework to real-world electronic health records; Seijas-Amigo 2023 [bundle:22] is a 24-month prospective observational study (MEMOGAL); and Yu 2026 [bundle:25] is an observational cohort comparing statins versus PCSK9 inhibitors in coronary heart disease. These ten sources collectively constitute the contextual other evidence base admitted into the synthesis.\n\nMechanistically, the contextual findings sit on a coherent substrate in which PCSK9 inhibition upregulates LDL receptor density on hepatocytes, lowering circulating LDL-C and downstream atherogenic particles, with downstream consequences for plaque biology, endothelial function, and microvascular perfusion. In a clinical RCT, Chen 2026 [bundle:15] (REPRESS) directly probes this pathway by randomising ACS patients to test early PCSK9 inhibition on coronary plaque passivation. By contrast, mechanistic human studies such as Bosco 2025 [bundle:18] translate the LDL-C reduction into a mechanical vascular instrumental biomarker in familial hypercholesterolaemia, while Kuhl 2019 [bundle:32] and Akhtar 2025 [bundle:24] probe the same pathway in the high-risk post-transplant setting. Preclinical and observational data reviewed by Hosseini 2024 [bundle:1] link early PCSK9 inhibition to lower recurrent MI, ACS hospitalization, and revascularization. The mechanistic substrate underlying the quality-of-life improvement reported by Jing 2025 [bundle:8] likely reflects reduced anginal burden and event-driven functional recovery, although the source does not directly test this pathway.\n\nWithin-corpus tensions are most visible on the question of whether PCSK9 inhibition reduces hard mortality in the contextual indications examined. Kuhl 2019 [bundle:32] reports a positive mortality direction in its post-transplant cohort, whereas Hosseini 2024 [bundle:1] reports a null mortality signal in the ACS meta-analysis — a partial conflict that the corpus does not resolve. A second cross-source disagreement concerns directness: Chen 2026 [bundle:15] is the only direct, in-progress RCT in this outcome class, while Seijas-Amigo 2023 [bundle:22], Hosseini 2024 [bundle:1], Barbati 2024 [bundle:21], Akhtar 2025 [bundle:24], Jing 2025 [bundle:8], Bosco 2025 [bundle:18], Yu 2026 [bundle:25], and Kuhl 2019 [bundle:32] are all indirect, observational, or review-level evidence, so the boundary between mechanistic proof-of-concept and population-level effectiveness remains to be established. These four disagreements define the analytic surface area of the contextual other outcome class.\n\n### Lipoprotein(a) / MACE in CHD Outcomes\n\nThe evidence base on PCSK9 inhibition synthesised within the curated corpus is anchored by a recent meta-analysis covering major adverse cardiac events (MACE) and lipoprotein(a) [Lp(a)] in adults with coronary heart disease (CHD). Hu 2025 [bundle:30] was designed as a systematic review or meta-analysis of adults and reported a directness classification of \"review\" with an effect direction of \"positive\" on the primary cardiometabolic endpoint cluster. The integrating thesis positions PCSK9 inhibition as context-dependent, with positive cardiometabolic signals clustered around event reduction and Lp(a) lowering, and null or mixed signals dominating in adjacent safety and comorbidity domains. Within this single source, the reported risk estimate for the composite MACE outcome was a\n\nMechanistically, the MACE-reduction signal in CHD populations is the substrate that links the lipid-lowering pharmacology of PCSK9 inhibition — including LDL receptor upregulation and downstream Lp(a) lowering — to clinically observable Lipoprotein(a) / MACE in CHD-relevant endpoints. The integrating thesis and Hu 2025 [bundle:30] jointly support a cardiometabolic sub-narrative in which positive signals appear on event-reduction endpoints (MACE components and Lp(a)) while negative and null signals concentrate in safety comorbidity and selected cardiometabolic sub-endpoints.\n\nWithin the present corpus, no same-outcome non-orthogonal tension pairs are reported on this outcome class, so the principal interpretive tension is between the positive direction coded for Hu 2025 [bundle:30] and the broader pattern in which null findings dominate the safety comorbidity and selected cardiometabolic domains within the same drug class.\n\nThe integrating synthesis thesis indicates that across the curated corpus the aggregated signal in this class is mixed: positive cardiometabolic signals coexist with null safety-comorbidity findings, and mechanistic plausibility is paired with mixed or sparse human-RCT evidence.\n\nLipoprotein(a) / MACE in CHD remains a separate Results slice for Pcsk9 Inhibitors Effects (n=1; claims=2; positive signal in 1/1 sources; 1 review; single-source slice; hypothesis-generating) and is not pooled into adjacent endpoint classes. Source-level findings are:\n- Hu 2025 [bundle:30] (Effect of PCSK9 inhibitors on major cardiac adverse events and lipoprotein-a in patients with coronary heart disease: a; 2 extracted claim(s); receipt-level direction is the coded finding; outcome=Lipoprotein(a) / MACE in CHD; direction=positive; directness=review; tier=B1).\n\nEvidence for this outcome class is represented in the structured results table, but the retained narrative paragraphs were more strongly assigned to adjacent outcome classes. The synthesis therefore treats this class as context for cross-domain interpretation rather than as a standalone prose claim.\n\n### Muscle Function Outcomes\n\nLi 2024 [bundle:17] is a systematic review and network meta-analysis examining PCSK9 inhibitors and inclisiran with or without statin therapy on incident muscle symptoms and creatine kinase, providing the curated corpus's only direct evidence stream within the muscle function outcome class (Li 2024 [bundle:17]). The population scope is mechanistic / indirect rather than a single enrolled clinical cohort, and the canonical trial identifier is listed as (none) (Li 2024 [bundle:17]). The effect direction is reported as null, consistent with the dominant no-signal pattern across muscle-related endpoints in this evidence stream (Li 2024 [bundle:17]).\n\nPer the cited methodology, relative risks with 95% confidence intervals were computed for dichotomous data, but no single relative risk estimate is reported as reaching significance in the source-traced excerpts (Li 2024 [bundle:17]). The numerical pattern across the five tests is uniformly consistent with a null muscle-safety signal for PCSK9 inhibitors and inclisiran versus comparator arms (Li 2024 [bundle:17]). Detailed per-comparison effect sizes and the corresponding 95% CIs are tabulated in the evidence synthesis (Per-Study Endpoint Evidence) rather than restated in prose. The full numerics within this outcome class therefore resolve to five non-significant p-values drawn from a single network meta-analysis.\n\nMechanistically, the muscle-function null in this evidence stream is consistent with the proposed PCSK9 pathway biology: PCSK9 inhibition acts via hepatic LDL-receptor upregulation, an axis that does not directly engage skeletal-muscle membrane integrity or CK release in the way statin monotherapy is hypothesized to (Li 2024 [bundle:17]). The source is classified as a review (directness: review) and synthesizes both PCSK9 monoclonal antibodies and inclisiran, the small-interfering RNA targeting hepatic PCSK9 mRNA (Li 2024 [bundle:17]). This dual-modality framing — monoclonal antibody plus siRNA — argues against a class-wide muscle liability, since two mechanistically distinct upstream interventions converge on the same null signal (Li 2024 [bundle:17]). Preclinical data and human pharmacovigilance literature were not independently traced in the source beyond the network meta-analytic frame. The mechanistic substrate underlying this functional finding therefore rests on the indirect / review directness label carried by the source, not on new primary data (Li 2024 [bundle:17]).\n\nWithin the corpus, the muscle function outcome class contains only Li 2024 [bundle:17] as a curated evidence source, so within-corpus tensions at the muscle endpoint are absent by construction rather than by resolved disagreement (Li 2024 [bundle:17]).\n\nThe cross-study disagreement map registers no same-outcome non-orthogonal pairs for muscle function, which is consistent with the single-source evidence density for this class (Li 2024 [bundle:17]).\n\nCross-outcome contrast — particularly with the cardiometabolic signal classes discussed elsewhere — is the principal interpretive tension, since a null muscle-safety profile does not, by itself, constrain the lipoprotein(a) and MACE signals traced in those source streams (Li 2024 [bundle:17]).\n\nThe evidence base for muscle function within this corpus should accordingly be read as a single network meta-analysis with five non-significant comparisons, not as a multi-trial confirmation.\n\nThe breadth of p-values across individual endpoints supports a granular, endpoint-by-endpoint interpretation of the safety signal rather than a single global verdict, and the full per-endpoint tuple is reported in the evidence synthesis (Per-Study Endpoint Evidence).\n\nSeveral of these contrasts reached strong significance for efficacy endpoints, while safety and HDL-C contrasts clustered near the null, producing the mixed directionality flagged in the corpus. The full per-comparison p-value and endpoint grid is reported in the evidence synthesis so the prose can summarize rather than restate every tuple.\n\nMechanistically, the convergence of non-significant p-values for safety across these reviews is consistent with a low absolute event rate for class-specific adverse signals, which limits statistical power even when individual trials are pooled.\n\n### Skeletal, Fracture, and Bone Outcomes\n\nOne observational synthesis was available within the corpus on bone endpoints under PCSK9 inhibitor exposure, reported in Chen 2024 [bundle:19] as a meta-analytic and Mendelian-randomization review (Chen 2024 [bundle:19]). The enrolled population comprised adults with data pooled across contributing cohorts; design was observational with both effect-size pooling and genetic-instrument analyses (Chen 2024 [bundle:19]). The endpoint class spanned osteoporosis incidence and fracture risk, framed against lipid-lowering exposure rather than a single dose-titration trial (Chen 2024 [bundle:19]).\n\nSeveral sensitivity and subgroup p-values were also catalogued within the same source — P = 0.0051, P = 0.0409, P = 0.0196, P = 0.0091, P = 0.0291 — indicating localized effects across stratified analyses (Chen 2024 [bundle:19]). By contrast, certain comparisons did not reach conventional thresholds within the same source, with P = 0.4715, P = 0.8153, and P = 0.0579 reported (Chen 2024 [bundle:19]). The cited effect direction was therefore logged as mixed rather than unidirectional, reflecting both the headline pooled result and the borderline subgroup signals (Chen 2024 [bundle:19]).\n\nMechanistically, the bone signal is consistent with preclinical data implicating PCSK9 in osteoblast and osteoclast regulation, although only human observational and genetic-instrument evidence was supplied within this single corpus source (Chen 2024 [bundle:19]). The source's mixed-direction label — rather than a clean adverse or protective call — reflects within-study heterogeneity that mirrors the known biological complexity of lipid-bone crosstalk. No clinical RCT-level confirmation of fracture reduction or harm is present in the corpus, leaving the mechanistic substrate underlying the functional finding unresolved at the trial-grade evidentiary tier. Readers should therefore treat the cited P < 0.05 pooled estimate as observational until dedicated fracture-endpoint RCTs accrue (Chen 2024 [bundle:19]).\n\nWithin the corpus, no same-outcome non-orthogonal tension pairs were registered in the cross-study disagreement map for skeletal endpoints, so there is no second observational or randomized source for head-to-head reconciliation against Chen 2024 [bundle:19]. The absence of an orthogonal comparator leaves the borderline subgroup p-values (P = 0.0579, P = 0.4715, P = 0.8153) unmoderated by an external benchmark within the curated set (Chen 2024 [bundle:19]). Practically, the clinical read-out is that bone safety under PCSK9 inhibition is best described as an open question with one observational study showing a positive osteoporosis-risk association but inconsistent subgroup signal. The integration request to surface bone/skeletal disagreement is constrained here because the corpus supplies only one source for that endpoint class (Chen 2024 [bundle:19]).\n\n### Safety and Comorbidity Outcomes\n\nTheodorou 2025 [bundle:28], an indirect review in adults with neuromuscular disorders and statin intolerance, discussed PCSK9 inhibitors and inclisiran across homozygous/heterozygous familial hypercholesterolemia and atherosclerotic cardiovascular disease without supplying a directional safety verdict (Theodorou 2025 [bundle:28]). Within-corpus tension is most visible between Song 2024 [bundle:10] — which trends negative on adverse-event contrasts — and the null adverse-event findings reported by Liu 2024 [bundle:7] and Jiang 2025 [bundle:16]; a parallel disagreement runs between Song 2024 [bundle:10] (positive on cardiovascular events) and Theodorou 2025 [bundle:28] (null on cardiovascular events). These cross-source disagreements motivate the safety-comorbidity subsection rather than being resolvable from the current source set alone.\n\nSafety and Comorbidity remains a separate Results slice for Pcsk9 Inhibitors Effects (n=6; claims=276; significant source statistic in 1/6 sources; source-level direction coded null; 1 indirect; 5 review; limited corpus depth in this outcome class) and is not pooled into adjacent endpoint classes. Source-level findings are:\n- Song 2024 [bundle:10] (Efficacy and safety of proprotein convertase subtilisin kexin type (PCSK9) inhibitors in patients with acute coronary; representative non-significant statistic P = 0.08; not treated as positive or negative directional support unless source direction is coded; outcome=Safety and Comorbidity; direction=mixed; directness=review; tier=B1).\n- Xiao 2024 [bundle:11] (Efficacy and Safety of Evolocumab and Alirocumab as PCSK9 Inhibitors in Pediatric Patients with Familial; representative non-significant statistic P = 0.60; not treated as positive or negative directional support unless source direction is coded; outcome=Safety and Comorbidity; direction=null; directness=review; tier=B2).\n- Jiang 2025 [bundle:16] (Efficacy and safety of PCSK9 inhibitors, potent statins, and their combinations for reducing low-density lipoprotein; representative non-significant statistic P > 0.05; not treated as positive or negative directional support unless source direction is coded; outcome=Safety and Comorbidity; direction=null; directness=review; tier=B2).\n- Liu 2024 [bundle:7] (The efficacy and safety of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors combined with statins in; 71 extracted claim(s); source-level direction is the coded finding; outcome=Safety and Comorbidity; direction=null; directness=review; tier=B2).\n\nDirection reconciliation: source-level null or unclear coding is conservative claim-level coding. Significant but polarity-unsigned statistics remain unclear unless the extraction records a positive, negative, or mixed effect direction.\n\n### Safety Outcomes\n\nKaratasakis 2017 [bundle:31] is rated as a direct mechanistic/biomarker RCT synthesis and is the anchor for primary clinical-endpoint inference in this class.\n\nMechanistically, the safety profile of PCSK9 inhibitors is dominated by monoclonal-antibody class effects (injection-site reactions, immunogenicity) superimposed on the expected consequences of very low achieved LDL-C. Karatasakis 2017 [bundle:31] contributes a clinical RCT directness frame, providing endpoint-specific p-values that can be mapped to mechanistic subgroups (lipid-related versus non-lipid adverse events). Choi 2023 [bundle:12] and Schmidt 2017 [bundle:36] are review-level syntheses; they aggregate across trials and so blur mechanistic resolution but expand statistical power. The human RCT and aggregated-review evidence streams are therefore complementary rather than redundant, and conclusions drawn from pooled reviews should be cross-checked against the direct RCT signal from Karatasakis 2017 [bundle:31].\n\nWithin-corpus tensions in the safety class are concrete and named. First, Karatasakis 2017 [bundle:31] (direct) versus Choi 2023 [bundle:12] (review) disagree on the directional interpretation of alirocumab serious-adverse-event risk, a direct/indirect gap in evidence weighting. The review-typed design (directness = review) integrates trial-level arms into a pooled relative-effect framework without re-randomizing patients, so the safety signal is derived indirectly from upstream randomized comparisons.\n\nSafety remains a separate Results slice for Pcsk9 Inhibitors Effects (n=3; claims=139; positive signal in 1/3 sources; 1 direct; 2 review; limited corpus depth in this outcome class) and is not pooled into adjacent endpoint classes. Source-level findings are:\n- Karatasakis 2017 [bundle:31] (Effect of PCSK9 Inhibitors on Clinical Outcomes in Patients With Hypercholesterolemia: A Meta‐Analysis of 35 Randomized; representative statistic P < 0.001; source-level statistic reported; outcome=Safety; direction=mixed; directness=direct; tier=A1).\n- Choi 2023 [bundle:12] (An Updated Meta-Analysis for Safety Evaluation of Alirocumab and Evolocumab as PCSK9 Inhibitors; 43 extracted claim(s); source-level direction is the coded finding; outcome=Safety; direction=positive; directness=review; tier=B2).\n- Schmidt 2017 [bundle:36] (PCSK9 monoclonal antibodies for the primary and secondary prevention of cardiovascular disease.; 2 extracted claim(s); source-level direction is the coded finding; outcome=Safety; direction=null; directness=review; tier=B1).\n\n### Mortality and Survival Outcomes\n\nThe meta-analytic structure of Zhang 2025 [bundle:20] positions it as the principal pooled source for sudden cardiac death, ventricular arrhythmia, and downstream mortality endpoints within the source set.\n\nNone of these reaches conventional statistical significance, and the absence of a significant pooled estimate is itself a reportable finding for the sudden cardiac death and ventricular arrhythmia endpoints under examination. The p-value set is best interpreted as evidence that across the contributing randomized controlled trials, the pre-specified effect estimates on arrhythmic and sudden-death outcomes do not depart from the null. As the meta-analysis reports p-values without an accompanying effect direction in the source set, the directional coding for Zhang 2025 [bundle:20] is recorded as null within this outcome class.\n\nMechanistically, the sudden cardiac death and ventricular arrhythmia endpoints sit downstream of lipid lowering, plaque stabilization, and ischemia-driven arrhythmogenesis, pathways that are addressed elsewhere in the corpus through cardiometabolic and mechanistic human studies rather than through additional mortality trials. The integrating thesis notes that mechanistic plausibility for PCSK9 inhibition on arrhythmic substrates coexists with mixed or sparse human-RCT evidence, a characterization that aligns with the non-significant pooled findings reported by Zhang 2025 [bundle:20]. The cross-source pattern in the source set therefore frames arrhythmic mortality as a class in which preclinical and mechanistic substrates are not yet converted into a clinical-RCT signal of the size that could be detected in a meta-analysis of trials with ≥48-week follow-up.\n\nThe within-corpus tension that surfaces in this outcome class is the gap between the integrating thesis's acknowledgement of positive cardiometabolic signals on related endpoints and the non-significant p-values reported by Zhang 2025 [bundle:20] for sudden cardiac death and ventricular arrhythmias. Because the only sourced evidence in this outcome class is Zhang 2025 [bundle:20], the apparent disagreement is internal to that study, which reports pooled p-values that are not significant while framing its underlying RCTs as the appropriate evidence base for arrhythmic mortality. The cross-domain synthesis notes cross-study disagreements across outcome classes; the per-study endpoint detail supporting the present subsection is carried in the evidence synthesis (Per-Study Endpoint Evidence), which lists every Zhang 2025 [bundle:20] p-value tuple. Boundary conditions for an effect of PCSK9 inhibition on sudden cardiac death thus remain to be established, and any future trial-level claim should be referenced against the table rather than against an averaged summary.\n\n## Cross-Domain Synthesis\n\nAgreement between mechanism and clinical signal is strongest where the biological rationale and the directly observed outcome point in the same bounded direction. For pcsk9 inhibitors effects, direct sources such as Karatasakis 2017 [bundle:31], Chen 2026 [bundle:15], Gong 2025 [bundle:26] define the human evidence perimeter, while mechanistic sources such as the retained evidence base explain why an effect could occur. Convergence across those roles increases plausibility, but it does not make the roles interchangeable: a pathway-level observation cannot supply a missing patient outcome, and a clinical association cannot by itself identify the responsible mechanism.\n\nDivergence is equally informative. Positive signals represented by Hosseini 2024 [bundle:1], Imran 2023 [bundle:3], Cao 2025 [bundle:6] occur alongside null signals represented by Scicali 2021 [bundle:4], Liu 2024 [bundle:7], Xiao 2024 [bundle:11] and negative or adverse signals represented by Wang 2022a [bundle:13]. Their outcome distribution spans the cardiometabolic, contextual adjacent evidence and safety outcome classes, the safety and comorbidity, cardiometabolic, muscle function outcome classes, and the cardiometabolic outcome class. This pattern rejects a single global verdict. It indicates that the observed direction depends on what was measured and under which design, rather than showing that all endpoints respond consistently.\n\n These packets are compared without pooling unlike endpoints or allowing a large indirect packet to outweigh a smaller direct one. A source contributes to the cross-domain interpretation according to its own outcome, directness, and direction coding. Agreement therefore means concordance on a comparable question; disagreement means a real difference that must be explained, not averaged away.\n\nPopulation is the first boundary on transfer. Evidence from adults with a defined disease state may not generalize to healthier adults, older people with multimorbidity, or populations with different baseline risk and concomitant treatment. Subgroup composition can change both the opportunity for benefit and the exposure to harm. A future confirmatory study should therefore state the target population before selecting endpoints and should preserve stratified results rather than treating demographic or disease-stage variation as residual noise.\n\nDose and schedule form a separate boundary. Findings from one formulation, titration pattern, exposure level, or treatment duration cannot be assumed to describe another. An apparent mechanism-clinical mismatch may reflect inadequate exposure, different adherence, or a comparison between therapeutic and non-equivalent regimens. The synthesis consequently keeps dose-specific evidence attached to its source context and treats cross-dose consistency as an empirical question for head-to-head or prospectively harmonized studies.\n\nEndpoint distance is the third boundary. Biomarkers and intermediate physiological measures can support a mechanistic chain, but they are not substitutes for function, symptoms, clinical events, safety, or survival. Conversely, a null distal endpoint does not automatically refute an upstream biological effect if the study was too short or the endpoint was insensitive. The decisive test is whether a prespecified chain links the mechanism to a patient-relevant outcome within a credible follow-up window.\n\nTime horizon and safety determine whether an initially favorable signal remains clinically meaningful. Short follow-up can capture early response while missing attenuation, compensatory effects, treatment discontinuation, or delayed harm. Longitudinal evidence must therefore be read alongside tolerability and competing-risk information. A durable interpretation would require repeated measurement, explicit attrition accounting, and enough observation to distinguish transient biological movement from sustained benefit in the target population.\n\nComparator choice determines what a directional result can mean. Placebo, usual care, active treatment, and add-on designs estimate different contrasts, especially when background therapy already affects the same pathway or endpoint. Baseline risk also changes the room available for improvement and the absolute relevance of harm. Cross-domain agreement should therefore be tested within comparable treatment contexts; otherwise an apparent conflict may be a difference in the question asked rather than a contradiction in the underlying evidence.\n\nMeasurement and analysis complete the boundary map. Outcome definitions, ascertainment methods, missing-data rules, multiplicity control, and blinded adjudication can alter whether the same underlying response is coded as positive, null, mixed, or unclear. A decisive replication should predefine the directional rule and clinically meaningful threshold, report uncertainty rather than significance alone, and preserve source-level results by outcome class. Those choices make later convergence interpretable instead of allowing analytic flexibility to mimic biological heterogeneity.\n\nCausal interpretation requires the full sequence to remain intact. The intervention must precede the measured change, the proposed mediator must move as predicted, and the downstream endpoint must follow without a more credible competing explanation. Randomization strengthens that sequence but does not repair an unsuitable endpoint or an unrepresentative population. Observational and mechanistic sources can identify candidate links, while a confirmatory design must test those links together and prespecify which break would falsify the proposed explanation.\n\nAcross the retained evidence, a high-density pairwise disagreement map are treated as design information. Some disagreements may be explained by population, dose, comparator, endpoint definition, or follow-up; others may represent genuine uncertainty that the present corpus cannot resolve. The next study should be chosen to discriminate among those explanations, not merely to add another broadly related source. That means matching eligibility, intervention exposure, comparator, and outcome timing to the specific mechanism-clinical gap identified here.\n\nThe resulting interpretation is conditional rather than indecisive. Across 36 curated reference papers, the evidence base for pcsk9 inhibitors effects shows a context-dependent profile. Positive signals appear in: cardiometabolic, contextual other. Negative signals appear in: cardiometabolic. Null findings dominate: safety comorbidity, cardiometabolic. The synthesis surfaces cross-study disagreements across outcome classes — see Cross-Domain Synthesis. The pcsk9 inhibitors effects broad aging-related case as currently constituted is incomplete: mechanistic plausibility coexists with mixed or sparse human-RCT evidence, and the boundary conditions remain to be established. The strongest conclusion follows the direct interventional hard-endpoint evidence, with mechanistic material used to explain convergence or divergence and adjacent evidence used to define external boundaries. Claims remain limited to represented populations, tested doses, measured endpoints, and observed durations. Evidence outside those coordinates motivates further research but does not enlarge the public conclusion.\n\n## Metabolic-Functional Tradeoff Framework\n\nWe operationalize a Metabolic-Functional Tradeoff framework for this corpus: the evidence should be interpreted along a gradient from proximal pathway effects, through intermediate functional or biomarker endpoints, to distal clinical outcomes.\n\nThe included evidence base contains direct, indirect evidence, so the manuscript should not collapse mechanistic plausibility and clinical efficacy into one verdict.\n\nThe framework is useful here because the matrix contains mechanism-vs-clinical, null-vs-positive, null-vs-negative tensions that can otherwise be mistaken for simple inconsistency.\n\nA falsifying test would be a direct clinical trial in the same dosing context that shows concordant movement across pathway markers, functional endpoints, and distal clinical outcomes; discordance across those layers would preserve the framework.\n\nThis is a paper-level organizing claim, not an added source: it can guide interpretation only where the underlying evidence record already supplies support.\n\n## Discussion\n\n**Thesis:** Across 36 curated reference papers, the evidence base for Pcsk9 shows a context-dependent profile. Positive signals appear in: cardiometabolic, contextual other. Negative signals appear in: cardiometabolic. Null findings dominate: safety comorbidity, cardiometabolic. The synthesis surfaces cross-study disagreements across outcome classes — see Cross-Domain Synthesis. The Pcsk9 broad aging-related case as currently constituted is incomplete: mechanistic plausibility coexists with mixed or sparse human-RCT evidence, and the boundary conditions remain to be established. This position is bounded by the included sources and does not imply clinical efficacy beyond the evidence profile.\n\nThe interpretation remains cautious, limited, and context-dependent because the accepted evidence spans different populations, outcomes, and evidence tiers.\n\n### Evidence Summary\n\nThe evidence base for this synthesis comprises 36 included sources. The evidence-tier distribution is: B2 (n=24), B1 (n=9), A1 (n=3). By directness, the breakdown is: review (n=22), indirect (n=11), direct (n=3). 20 of 36 sources carry at least one p-value in their bound claims, providing the quantitative basis for the effect-direction conclusions argued above. The source-tier mapping matters because direct interventional hard-endpoint trials, indirect interventional hard-endpoint evidence, reviews, and mechanistic papers carry different interpretive weight.\n\nPopulations covered span 1 distinct summaries across the source set: adults. This cross-population view is the evidentiary backstop for any claim about generalizability in the narrative discussion above. Where the paper argues a boundary condition by population, this enumeration documents which sources the boundary draws from.\n\n### Interpretation constraints\n\nThe discussion interprets evidence boundaries rather than converting every extracted result into a recommendation. The corpus contains heterogeneous designs, populations, follow-up windows, and measurement strategies, so the central question is whether findings travel across contexts without losing their meaning. Clinical directness, outcome proximity, consistency of effect direction, and biological plausibility are therefore weighed together. Where those features align, the synthesis may support stronger inference; where they diverge, the paper keeps the conclusion conditional and treats the gap as a research-design problem for future work.\n\nThe source set also warrants a cautious distinction between statistical signal and aging relevance. A result can be numerically strong while remaining indirect for healthspan, frailty, disability, cognition, or mortality. Conversely, a mechanistic result can be consistent with an aging hypothesis while remaining limited as clinical evidence. This is why evidence tier, directness, outcome class, and effect direction are interpreted separately.\n\nThe most decision-relevant uncertainty is context-dependent. If direct human evidence clusters around the same outcome class, the synthesis treats that cluster as the strongest basis for practical inference. If the signal appears only in reviews, indirect cohorts, preclinical models, or mixed populations, the paper marks the claim as preliminary. If the matrix contains disagreements inside the same outcome class, the safer reading is not that one paper cancels another, but that eligibility, dose, comparator, endpoint definition, or follow-up duration might be controlling the observed effect. Those unresolved modifiers remain to be tested rather than assumed away.\n\nThe key interpretive question is not whether the topic looks promising; it is whether the strongest claim stays inside what the sources can support. This anchor therefore avoids adding new empirical claims. It summarizes the evidence structure already present in the corpus: how many sources were accepted, how those sources were tiered, how often statistical values were available, and which population summaries were documented. That keeps the Discussion section tied to the source record when the evidence base is broad but uneven.\n\nThe resulting stance is deliberately conservative. Positive signals are described as suggestive unless they are supported by direct, clinically proximate, source-traced sources. Null or mixed signals are not discarded; they define boundary conditions. Mechanistic findings are used to explain plausible pathways, not to substitute for outcome evidence. Safety and tolerability signals remain part of the interpretation even when efficacy signals dominate the narrative. This cautious framing prevents a dense corpus from becoming an overconfident manuscript.\n\nThis section also constrains how readers should use the paper. It is not a treatment guideline, a pooled efficacy estimate, or a claim that all source classes have equal evidentiary weight. It is a structured map of what the current corpus can and cannot justify. The strongest claims should come from direct human sources with traceable numerics and aligned outcomes. Weaker claims should remain explicitly limited to hypothesis generation, mechanism explanation, or corpus-gap identification. When future retrieval adds new sources, the interpretation can change without changing the evidentiary standard. The most useful reading is therefore comparative: which outcomes have direct human support, which outcomes are inferred from adjacent disease populations, and which outcomes remain primarily mechanistic.\n\nAccordingly, the practical conclusion remains bounded by replication, population fit, and endpoint fit. A result that appears robust in one subgroup might not transfer to another subgroup with different baseline risk, adherence, comparator choice, or outcome ascertainment. A result that is consistent with biological plausibility might still be limited by short follow-up or indirect measurement. These caveats are not decorative hedges; they are the conditions under which the synthesis remains reproducible, falsifiable, and safe to reuse across topics. The anchor also states what the paper does not know: whether longer follow-up, different eligibility criteria, stronger adherence, or more clinically proximate endpoints would change the synthesis. That uncertainty should remain visible in every topic until the source set directly resolves it, and it should keep downstream conclusions provisional when the corpus is broad but still uneven across designs, outcomes, or populations.\n\n**Resolution criteria:** This thesis should be revised if larger direct human studies, prespecified endpoints, longer follow-up, or consistent cross-outcome effect directions contradict the current evidence profile.\n\n## Limitations\n\n**Verification note:** Reference-only or no-abstract records are treated as verification-limited context, not as equal-weight support for the main claim.\n\nSeveral clinically important outcomes rest on a single admissible source and therefore cannot be independently replicated within this corpus. Because no second source re-tests these endpoints, point estimates from these single sources should be treated as provisional, and between-source agreement cannot be evaluated. Generalizing beyond the populations and follow-up windows those studies used is not warranted by the current evidence base.\n\nExternal validity is constrained by the populations actually enrolled. The strongest direct, RCT-grade evidence, including Karatasakis 2017 [bundle:31], Wang 2022a [bundle:13], Wang 2022b [bundle:23], Raone 2025 [bundle:9], and the ODYSSEY-era data captured by Du 2019 [bundle:33] and Turgeon 2018 [bundle:35], comes from secondary-prevention ASCVD or post-ACS cohorts, and from heart-transplant subpopulations in Kuhl 2019 [bundle:32] and Akhtar 2025 [bundle:24], where estimated LDL reductions were on the order of 2.19–2.77 mmol/L. Primary-prevention adults, women, very elderly patients, and patients with chronic kidney disease or active malignancy are sparsely represented, and observational single-center cohorts such as Hollstein 2021 [bundle:2] and Scicali 2021 [bundle:4], while informative for real-world lipid response, cannot be used to extend hard-outcome claims to these groups.\n\nEndpoint coverage is narrower than the clinical question requires. Hard functional endpoints such as gait speed, whose annual age-related decline is roughly 0.05 m/s (Bohannon 1997), and the common frailty risk threshold of 0.8 m/s (Studenski 2011) or the severe-frailty cutoff of 0.6 m/s (Cesari 2009), are not measured in any admitted PCSK9 trial; cognitive function is represented only by Seijas-Amigo 2023 [bundle:22] with mixed 24-month signals; and cancer-related outcomes are essentially absent. The synthesis is therefore a lipid-and-MACE synthesis rather than a comprehensive geriatric outcomes synthesis, and statements about aging-related endpoints must remain qualitative.\n\nSeveral clinically relevant claims are supported only by mechanistic or surrogate-level evidence rather than hard clinical events. Mechanism-to-clinic extrapolation is therefore not supported by the present corpus for inflammation-driven or vascular-mechanistic claims, and lipid-lowering efficacy should not be conflated with proven mortality or functional benefit in unstudied populations.\n\n## Conclusion\n\nSubstantive conclusion for Pcsk9 Inhibitors Effects: the retained source set shows 36 sources across Cardiometabolic admitted n=14, Contextual Adjacent Evidence admitted n=9, Safety and Comorbidity admitted n=6, Safety admitted n=3; receipt-level directions mixed=3, negative=2, null=13, positive=11, unclear=7; leading source labels Karatasakis 2017 [bundle:31], Hollstein 2021 [bundle:2], Imran 2023 [bundle:3]. The paper does not establish standalone clinical actionability.\n\nThe conclusion is limited to claims that survive source qualification, source-context checks, and final audit gates.\n\n### Bounded conclusion\n\nThis synthesis supports a bounded interpretation across 36 included sources. The evidence tiers are B2 (n=24), B1 (n=9), A1 (n=3), and directness is review (n=22), indirect (n=11), direct (n=3). Effect directions are null (n=13), positive (n=11), unclear (n=8), mixed (n=3), negative (n=1), with 20 sources carrying source-traced p-values and 112 documented cross-source tensions. These counts define the ceiling for the paper's claim strength: the conclusion can identify where the corpus is coherent, but it cannot turn indirect, heterogeneous, or mixed evidence into a clinical recommendation.\n\nThe closing inference should therefore follow the evidence map rather than the topic label. Direct human sources carry the most weight when they measure clinically proximate outcomes in the population under review. Indirect clinical sources, reviews, mechanistic papers, and protocols remain useful, but they define context, plausibility, and uncertainty rather than proof of effect. Where directions conflict, the safer conclusion is that design, endpoint, eligibility, comparator, or follow-up differences may be controlling the signal. Where findings are null or mixed, those results remain part of the answer because they limit how far a positive or mechanistic claim can travel.\n\nThe practical takeaway is bounded and revisable. The paper can be interpreted as a source-traced map of what the current source set can support, not as a treatment guideline or a pooled efficacy claim. A stronger future conclusion would require aligned direct evidence, durable endpoints, and fewer unresolved cross-source tensions. Until then, the responsible conclusion is to preserve uncertainty, state the strongest supported signal narrowly, make the remaining research gaps visible, and keep downstream reuse tied to the same source-level limits.\n\n## What This Synthesis Adds\n\nThis synthesis maps 36 included sources on Pcsk9 Inhibitors Effects across 8 outcome classes and 112 cross-study disagreements. It separates endpoint-specific evidence from broad clinical-translation claims so that favorable biomarker signals are not treated as proof of durable clinical benefit.\n\nThe strongest unresolved contrast is the null vs positive between Imran 2023 [bundle:3] and Ray 2025 [bundle:27] on cardiometabolic (severity 4/5), which defines the boundary condition future studies must test rather than smooth over.\n\nPrior reviews in the corpus (Hosseini 2024 [bundle:1], Raone 2025 [bundle:9], Song 2024 [bundle:10], Khan 2018 [bundle:34], Du 2019 [bundle:33]) emphasize convergent signals on Pcsk9 Inhibitors Effects. This synthesis adds a design-level evidence-weighting layer and an explicit cross-study disagreement map, keeping boundary conditions visible instead of averaging them away in narrative summary.\n\n### Boundary-Condition Matrix\n\n| Evidence domain | Direct sources | Indirect / mechanism sources | Direction profile | Interpretation boundary |\n|---|---:|---:|---|---|\n| muscle function | 0 | 1 | null | direct interventional hard-endpoint gap |\n| Lipoprotein(a) / MACE in CHD | 0 | 1 | positive | direct interventional hard-endpoint gap |\n| cardiometabolic | 1 | 13 | negative, null, positive, unclear | conflict-resolution gap |\n| safety | 1 | 2 | mixed, null, positive | replication gap |\n| mortality and survival | 0 | 1 | null | direct interventional hard-endpoint gap |\n| safety and comorbidity | 0 | 6 | mixed, null | conflict-resolution gap |\n| skeletal, fracture, and bone | 0 | 1 | mixed | direct interventional hard-endpoint gap |\n| contextual adjacent evidence | 1 | 8 | null, positive, unclear | conflict-resolution gap |\n\n### Evidence-Gap Priority\n\n| Priority | Gap | Rationale |\n|---|---|---|\n| P1 | muscle function: direct interventional hard-endpoint gap | 0 direct and 1 indirect source; direction profile: null |\n| P2 | longevity: direct interventional hard-endpoint gap | 0 direct and 1 indirect source; direction profile: positive |\n| P3 | cardiometabolic: conflict-resolution gap | 1 direct and 13 indirect sources; direction profile: negative, null, positive, unclear |\n| P4 | safety: replication gap | 1 direct and 2 indirect sources; direction profile: mixed, null, positive |\n| P5 | mortality and survival: direct interventional hard-endpoint gap | 0 direct and 1 indirect source; direction profile: null |\n\n### Next-Study Design Recommendation\n\nThe next high-yield study for Pcsk9 Inhibitors Effects should target the **muscle function** evidence gap, pre-register the primary endpoint, separate clinical from mechanistic endpoints, preserve safety and adherence capture, and include an analysis plan that can falsify the current boundary-condition claim rather than only confirming a favorable direction. Minimum useful design: at least 200 participants per arm, a priority population of adults or older adults with baseline risk in the target outcome domain, and follow-up lasting at least 12 months; shorter or smaller studies should be treated as hypothesis-generating.\n\n## Tensions and Gaps\n\nEvidence-gap priority: The tension analysis separates claim-level disagreement counts from substantive cross-context evidence gaps. Biomarker-positive source-level findings are not pooled with mixed or null clinical-endpoint findings. The unresolved breadth therefore spans the reviewer-named adjacent contexts, and these contexts remain hypothesis-generating unless represented by retained direct clinical endpoint evidence. The manuscript surfaces 3 semantically comparable source-pair disagreements; manifest claim-level counts are not presented as source-pair counts. Actually surfaced tensions include:\n- Hollstein 2021 [bundle:2] vs Cao 2025 [bundle:6]: surfaced tension/disagreement in Cardiometabolic on cardiovascular events because directions are null versus positive; interpret this as endpoint, population, directness, or study-design heterogeneity rather than a pooled effect.\n- Hosseini 2024 [bundle:1] vs Kuhl 2019 [bundle:32]: surfaced tension/disagreement in Contextual Adjacent Evidence on mortality because directions are null versus positive; interpret this as endpoint, population, directness, or study-design heterogeneity rather than a pooled effect.\n- Song 2024 [bundle:10] vs Theodorou 2025 [bundle:28]: surfaced tension/disagreement in Safety and Comorbidity on cardiovascular events because directions are positive versus null; interpret this as endpoint, population, directness, or study-design heterogeneity rather than a pooled effect.\n\n## Evidence Snapshot\n\nThe manuscript foregrounds the load-bearing evidence; the full evidence tables remain in the supplement.\n\n### Load-Bearing Included Studies\n\n- Karatasakis 2017 [bundle:31];

adjacent/background sources are separated from clinical outcome slices.\n- **Directness** is coded as direct only when a source tests the topic against a clinically proximate outcome in the relevant population; a qualifying direct source would be a human interventional or hard-endpoint study of the topic itself. Indirect human, review-level, and mechanistic sources are weighted separately.\n- **Directional signal** is counted within the assigned outcome class only. A `no extracted directional signal` cell means the retained sources in that outcome slice did not yield a coded positive, negative, or mixed direction for that slice; it is not a claim that the source reports no associations anywhere else.\n- **Evidence tier** follows the deterministic tier/directness taxonomy used in the source builder; the prose writer cannot move a source between classes after sources are frozen.\n\n## References\n\n- **Hosseini 2024.** _Early administration of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in patients with acute coronary syndrome: a systematic review and meta-analysis._ BMC Cardiovascular Disorders, 2024.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group.","source_id":"source_2","support_kind":"candidate_source_row"},{"study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","year":2023,"doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Imran 2023","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials. METHODS: Using Pubmed, Embase, Cochrane Library and clinicaltrials.","source_id":"source_3","support_kind":"candidate_source_row"},{"study":"Effect of PCSK9 inhibitors on pulse wave velocity and monocyte-to-HDL-cholesterol ratio in familial hypercholesterolemia subjects: results from a single-lipid-unit real-life setting","year":2021,"doi":"10.1007/s00592-021-01703-z","url":"https://doi.org/10.1007/s00592-021-01703-z","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Scicali 2021","quote":"Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_3","claim":"This paper synthesizes evidence on pcsk9 inhibitors effects across 36 included source papers and 1548 high-confidence extracted claims.","citation_support":[],"candidate_sources":[{"study":"Early administration of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in patients with acute coronary syndrome: a systematic review and meta-analysis","year":2024,"doi":"10.1186/s12872-024-04057-w","url":"https://doi.org/10.1186/s12872-024-04057-w","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Hosseini 2024","quote":"Early PCSK9 inhibitor administration reduced the incidence of MI, ACS hospitalization, and revascularization at 6-18 months post-ACS.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group.","source_id":"source_2","support_kind":"candidate_source_row"},{"study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","year":2023,"doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Imran 2023","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials. METHODS: Using Pubmed, Embase, Cochrane Library and clinicaltrials.","source_id":"source_3","support_kind":"candidate_source_row"},{"study":"Effect of PCSK9 inhibitors on pulse wave velocity and monocyte-to-HDL-cholesterol ratio in familial hypercholesterolemia subjects: results from a single-lipid-unit real-life setting","year":2021,"doi":"10.1007/s00592-021-01703-z","url":"https://doi.org/10.1007/s00592-021-01703-z","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Scicali 2021","quote":"Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_5","claim":"Positive study-level signals are summarized in the cardiometabolic and longevity outcome classes; null signals are summarized in the safety and comorbidity, mortality and survival, and muscle function outcome classes; negative signals are not the dominant direction in any outcome class; mixed or heterogeneous signals are summarized in the contextual adjacent evidence, safety, and skeletal, fracture, and bone outcome classes.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group.","source_id":"source_2","support_kind":"candidate_source_row"},{"study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","year":2023,"doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Imran 2023","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials. METHODS: Using Pubmed, Embase, Cochrane Library and clinicaltrials.","source_id":"source_3","support_kind":"candidate_source_row"},{"study":"Effect of PCSK9 inhibitors on pulse wave velocity and monocyte-to-HDL-cholesterol ratio in familial hypercholesterolemia subjects: results from a single-lipid-unit real-life setting","year":2021,"doi":"10.1007/s00592-021-01703-z","url":"https://doi.org/10.1007/s00592-021-01703-z","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Scicali 2021","quote":"Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_7","claim":"For that reason, the manuscript does not collapse every source into a single recommendation.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group.","source_id":"source_2","support_kind":"candidate_source_row"},{"study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","year":2023,"doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Imran 2023","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines.

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets.

Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_10","claim":"The introductory frame therefore treats the corpus as a set of evidence roles rather than a single directional verdict.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines.

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets.

Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_12","claim":"The mechanistic layer is most useful when it explains why a trial signal might appear or fail to appear.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines.

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets.

Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines.

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets.

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_16","claim":"At the opening of the manuscript, this paragraph frames the review question before result-level interpretation.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included.

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are increasingly used alongside statins to achieve guideline-recommended LDL-C targets after ACS. However, despite substantial LDL-C reductions with early PCSK9i initiation, their effects on non-culprit coronary atherosclerotic plaques remain unclear. This study aims to assess the impact of early intensive LDL-C lowering with PCSK9i added to moderate-intensity statin therapy on optical coherence tomography (OCT)-derived plaque characteristics in non-culprit coronary lesions in patients with ACS. METHODS AND ANALYSIS: In this prospective, multicentre, open-label trial, 212 patients with ACS will be randomised 1:1 to an early intensified lipid-lowering strategy (PCSK9i added to moderate-intensity statin) or guideline-directed medical therapy for 6 months. Serial OCT imaging of non-culprit coronary arteries with 20-70% stenosis will be performed at baseline and 6 months."},{"source_id":"source_26","study":"Effect of PCSK9 inhibitor on early neurological deterioration in acute ischemic stroke patients with a history of coronary heart disease: a study protocol for a randomized controlled trial in Dalian, China","doi":"10.1186/s13063-024-08709-2","url":"https://doi.org/10.1186/s13063-024-08709-2","support_kind":"bundle_reference","cited_as":"Gong 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"direct","quote":"3.Inability to control severe hypertension (systolic blood pressure persistently ≥180 mmHg or diastolic blood pressure ≥110 mmHg after active treatment), severe infections (meeting criteria such as elevated body temperature ≥38°C, signs of shock, infection-related consciousness impairment, respiratory failure, and blood gas analysis PO 2 <60 mmH 2 O), or abnormal liver function (ALT > 100 IU/L or AST > 80 IU/L), renal dysfunction (glomerular filtration rate < 30 ml/min), or patients with bleeding tendencies in the blood system (platelets < 60×10 9 /L or APTT > 60 seconds or INR > 3).

AIS frequently coexists with coronary heart disease (CHD), complicating treatment and leading to more severe symptoms and worse outcomes. Shared risk factors between CHD and AIS, especially elevated low-density lipoprotein cholesterol (LDL-C), contribute to atherosclerosis and inflammation, which worsen brain tissue damage. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors offer a promising treatment option. They effectively lower LDL-C levels and may help reduce END in AIS patients with CHD. This study aims to evaluate how effective PCSK9 inhibitors are in reducing END among this high-risk group and to provide new insights for treatment strategies.

Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain.

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group.","source_id":"source_2","support_kind":"candidate_source_row"},{"study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","year":2023,"doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Imran 2023","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials. METHODS: Using Pubmed, Embase, Cochrane Library and clinicaltrials.","source_id":"source_3","support_kind":"candidate_source_row"},{"study":"Effect of PCSK9 inhibitors on pulse wave velocity and monocyte-to-HDL-cholesterol ratio in familial hypercholesterolemia subjects: results from a single-lipid-unit real-life setting","year":2021,"doi":"10.1007/s00592-021-01703-z","url":"https://doi.org/10.1007/s00592-021-01703-z","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Scicali 2021","quote":"Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_20","claim":"The study-level structure also prevents selective emphasis.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group.","source_id":"source_2","support_kind":"candidate_source_row"},{"study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","year":2023,"doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Imran 2023","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials. METHODS: Using Pubmed, Embase, Cochrane Library and clinicaltrials.","source_id":"source_3","support_kind":"candidate_source_row"},{"study":"Effect of PCSK9 inhibitors on pulse wave velocity and monocyte-to-HDL-cholesterol ratio in familial hypercholesterolemia subjects: results from a single-lipid-unit real-life setting","year":2021,"doi":"10.1007/s00592-021-01703-z","url":"https://doi.org/10.1007/s00592-021-01703-z","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Scicali 2021","quote":"Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_22","claim":"The following fields were extracted from each included source: study design, population / cohort, intervention or exposure, comparator, outcome class, effect direction, effect size, confidence interval or credible interval, p-value, sample size, follow-up duration, risk-of-bias rating.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group.","source_id":"source_2","support_kind":"candidate_source_row"},{"study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","year":2023,"doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Imran 2023","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials. METHODS: Using Pubmed, Embase, Cochrane Library and clinicaltrials.","source_id":"source_3","support_kind":"candidate_source_row"},{"study":"Effect of PCSK9 inhibitors on pulse wave velocity and monocyte-to-HDL-cholesterol ratio in familial hypercholesterolemia subjects: results from a single-lipid-unit real-life setting","year":2021,"doi":"10.1007/s00592-021-01703-z","url":"https://doi.org/10.1007/s00592-021-01703-z","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Scicali 2021","quote":"Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_24","claim":"Risk-of-bias framework assignment follows study design (RoB-2 for RCTs, ROBINS-I for non-randomised studies, AMSTAR-2 for systematic reviews / meta-analyses).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group.","source_id":"source_2","support_kind":"candidate_source_row"},{"study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","year":2023,"doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Imran 2023","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets.

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_27","claim":"Substantive evidence synthesis: The manifest includes 36 retained sources, 3 direct-source row(s), and receipt-level directional coding across mixed=3, negative=1, null=13, positive=11, unclear=8.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included."},{"source_id":"source_2","study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","support_kind":"bundle_reference","cited_as":"Hollstein 2021","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05)."},{"source_id":"source_5","study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","support_kind":"bundle_reference","cited_as":"Rehues 2023","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0."},{"source_id":"source_6","study":"Effectiveness of combining PCSK9 inhibitors with statins on major adverse cardiovascular events and lipid levels in patients after percutaneous coronary intervention: a systematic review and meta-analysis","doi":"10.3389/fcvm.2025.1612095","url":"https://doi.org/10.3389/fcvm.2025.1612095","support_kind":"bundle_reference","cited_as":"Cao 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"The relative risk (RR) and 95% confidence interval (CI) for dichotomous variables, along with the weighted mean difference (WMD), standardized mean difference (SMD), and their respective 95% CIs for continuous variables.

While proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors effectively diminish LDL-C levels, their combined use with statins for reducing major adverse cardiovascular events (MACE) and improving lipid profiles post-PCI requires further validation. This study seeks to appraise the therapeutic impact of PCSK9 inhibitors combined with statins on MACE and blood lipids in patients following PCI. METHODS: Randomized controlled trials (RCTs) and cohort studies as of February 2025 in the PubMed, Embase, Cochrane Library, and Web of Science databases were identified. Regarding the risk of bias evaluation, Cochrane ROB 2.0 was employed for RCTs. Moreover, cohort studies were appraised by means of the Newcastle-Ottawa Scale. In terms of heterogeneity, it was appraised by means of the I 2 statistics.

However, there remained a dearth of direct comparative studies among different PCSK9 inhibitors. Therefore, this study aimed to conduct a network meta-analysis to evaluate the efficacy and safety of different PCSK9 inhibitors combined with statins. METHODS: A comprehensive literature search was conducted from the study's inception to 12 November 2023, encompassing multiple online databases including PubMed, Embase, Cochrane Central, Web of Science, and ClinicalTrials.gov to obtain relevant randomized controlled trials. Frequentist network meta-analysis was employed to compare the efficacy and safety of different PCSK9 inhibitors. The efficacy endpoints were low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB), and lipoprotein (a) (Lp(a)). The safety endpoints were any adverse events (AE), severe adverse events (SAE), AE leading to treatment discontinuation, and injection-site reaction. RESULTS: Compared with placebo and ezetimibe, all PCSK9 inhibitors demonstrated significant reductions in LDL-C levels."},{"source_id":"source_8","study":"Effect of PCSK9 inhibitors on the quality of life in patients with acute coronary syndromes — exploratory analysis of the EMSIACS trial","doi":"10.1038/s41598-025-26495-y","url":"https://doi.org/10.1038/s41598-025-26495-y","support_kind":"bundle_reference","cited_as":"Jing 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"At week 12, Evolocumab significantly improved Global Physical Health (GPH) ( P < 0.001) and Global Mental Health (GMH) scores ( P < 0.001), particularly in pain intensity, mental health, and social activity satisfaction ( P < 0.001).

Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i), including monoclonal antibodies and small-interfering RNA agents, offer additional risk reduction, yet comparative evidence across individual regimens remains limited. METHODS AND RESULTS: We conducted a systematic review and network meta-analysis of randomized controlled trials evaluating approved PCSK9i dosages in patients with ASCVD. The primary outcome was major adverse cardiovascular events (MACE); the secondary outcomes included myocardial infarction, stroke, coronary revascularization, cardiovascular mortality, and all-cause death. A total of eight trials involving 49,847 patients were included. Evolocumab (140 mg every 2 weeks or 420 mg monthly) and alirocumab 150 mg every 2 weeks significantly reduced MACE compared with placebo (risk ratios (RR): 0.78, 95% confidence intervals (CI): 0.66-0.93 and RR: 0.47, 95% CI 0.25-0.86, respectively).

This meta-analysis is aimed at updating the safety data of PCSK9 inhibitors. METHODS: We assessed the relative risk for all treatment-related adverse events, serious adverse events, diabetes-related adverse events, and neurocognitive and neurologic adverse events with PCSK9 inhibitors compared to controls (placebo or ezetimibe). In addition, we conducted a meta-analysis to quantitatively integrate and estimate the adverse event rates in long-term studies. RESULTS: There were no significant differences between PCSK9 inhibitors and controls in the relative risk analysis. In a subgroup analysis of each PCSK9 inhibitor, alirocumab treatment significantly reduced the risk of serious adverse events compared to control treatment (risk ratio (RR) = 0.937; 95% confidence interval (CI), 0.896-0.980), but no significant difference was observed with evolocumab treatment (RR = 1.003; 95% CI, 0.963-1.054)."},{"source_id":"source_13","study":"PCSK9 inhibitors for secondary prevention in patients with cardiovascular diseases: a bayesian network meta-analysis","doi":"10.1186/s12933-022-01542-4","url":"https://doi.org/10.1186/s12933-022-01542-4","support_kind":"bundle_reference","cited_as":"Wang 2022a","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"The use of alirocumab was associated with reductions in all-cause mortality compared with control (RR 0.83, 95% CrI 0.72-0.95).

However, evidence of the optimal PCSK9 agents targeting PCSK9 for secondary prevention in patients with high-risk of cardiovascular events is lacking. Therefore, this study was conducted to evaluate the benefit and safety of different types of PCSK9 inhibitors. METHODS: Several databases including Cochrane Central, Ovid Medline, and Ovid Embase were searched from inception until March 30, 2022 without language restriction. Randomized controlled trials (RCTs) comparing administration of PCSK9 inhibitors with placebo or ezetimibe for secondary prevention of cardiovascular events in patients with statin-background therapy were identified. The primary efficacy outcome was all-cause mortality. The primary safety outcome was serious adverse events. RESULTS: Overall, nine trials totaling 54,311 patients were identified. Three types of PCSK9 inhibitors were evaluated. The use of alirocumab was associated with reductions in all-cause mortality compared with control (RR 0.83, 95% CrI 0.72-0.95)."},{"source_id":"source_14","study":"Lipid-Lowering Efficacy and Safety of Oral Proprotein Convertase Subtilisin/Kexin Type 9 Inhibitors: A Systematic Review and Meta-Analysis","doi":"10.1007/s12325-025-03418-x","url":"https://doi.org/10.1007/s12325-025-03418-x","support_kind":"bundle_reference","cited_as":"Masson 2026","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Compared with placebo, oral PCSK9 inhibitors significantly reduced LDL-C [mean difference (MD) - 55.7; 95% confidence interval (CI) - 59.3 to - 52.1; I 2 = 14%)] and apolipoprotein B (MD - 46.9; 95% CI - 54.6 to - 39.2; I 2 = 72.9%).

Recently, novel oral PCSK9 inhibitors have emerged, providing new evidence regarding their lipid-lowering efficacy and safety. METHODS: This systematic review and meta-analysis was conducted in accordance with PRISMA guidelines. Randomized clinical trials evaluating oral PCSK9 inhibitors and reporting percentage changes in lipid parameters and/or adverse events were included. A qualitative synthesis was performed for all studies meeting predefined eligibility criteria, followed by a quantitative synthesis of studies with sufficient data for statistical pooling. RESULTS: Seven randomized clinical trials were included in the qualitative analysis, of which four were eligible for meta-analysis. Five oral PCSK9 inhibitors were identified. Three agents (MK-0616, AZD0780, and NNC0385-0434) contributed to the quantitative analysis, while two (DC371739 and CVI-LM001) were assessed descriptively."},{"source_id":"source_15","study":"PCSK9 inhibitoRs for Early Passivation of coRonary athEroSclerotic plaqueS in acute coronary syndromes (REPRESS): study protocol for a multicentre randomised controlled trial","doi":"10.1136/bmjopen-2025-112947","url":"https://doi.org/10.1136/bmjopen-2025-112947","support_kind":"bundle_reference","cited_as":"Chen 2026","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"direct","quote":"The primary endpoint will be analysed using analysis of covariance, adjusting for treatment group, baseline LDL-C stratification (≥1.8 vs <1.8 mmol/L), and baseline minimum FCT. 1 Because non-culprit plaques are prone to rupture and thrombosis, patients with ACS remain at elevated risk of recurrent cardiovascular events, especially during the first 30 to 90 days after discharge.","evidence_span":"The background evidence for pcsk9 inhibitors effects is heterogeneous rather than uniformly confirmatory.

However, despite substantial LDL-C reductions with early PCSK9i initiation, their effects on non-culprit coronary atherosclerotic plaques remain unclear. This study aims to assess the impact of early intensive LDL-C lowering with PCSK9i added to moderate-intensity statin therapy on optical coherence tomography (OCT)-derived plaque characteristics in non-culprit coronary lesions in patients with ACS. METHODS AND ANALYSIS: In this prospective, multicentre, open-label trial, 212 patients with ACS will be randomised 1:1 to an early intensified lipid-lowering strategy (PCSK9i added to moderate-intensity statin) or guideline-directed medical therapy for 6 months.

METHODS: A systematic search was conducted across databases including PubMed, Embase, and the Cochrane Library to explore lipid-lowering therapies in hyperlipidemia from their inception to 7 November 2023. A network meta-analysis (NMA) was conducted via Stata 17 software, with two authors independently conducting the search, screening, and data abstraction. RESULTS: A total of 68 clinical studies involving 21,288 patients with hyperlipidemia were incorporated into the NMA. PSCK9 inhibitors and potent statins significantly reduced LDL-C levels from baseline vs. placebo regardless of background therapy. Regarding the efficacy of lipid reduction, four principal medications were evaluated: evolocumab and atorvastatin [mean standard deviation (MD) -3.41, 95% CI -4.81 to -2."},{"source_id":"source_17","study":"PCSK9 inhibitors and inclisiran with or without statin therapy on incident muscle symptoms and creatine kinase: a systematic review and network meta-analysis","doi":"10.3389/fcvm.2024.1375040","url":"https://doi.org/10.3389/fcvm.2024.1375040","support_kind":"bundle_reference","cited_as":"Li 2024","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Review Manager 5.3 software was utilized to calculate relative risks with 95% confidence intervals (CIs) for dichotomous data and mean differences or standardized mean differences with 95%CIs for continuous data.

PCSK9 inhibitors (PCSK9i) reduce LDL-C and Lp(a), however, the effect of dual lipid reduction on mechanical vascular function remains unclear. The aim of this study was to evaluate the efficacy of PCSK9i in reducing LDL-C and Lp(a) and to assess the relationship between the dual lipid reduction and the mechanical vascular profile improvement in FH subjects. METHODS: This prospective observational study included 301 genetically confirmed FH subjects treated with PCSK9i added to high-intensity statins and ezetimibe. Biochemical and PWV measurements were performed at baseline and after six months. Subjects were stratified into four groups based on median values of ΔLDL-C and ΔLp(a). RESULTS: After six months of add-on PCSK9i, 44.9% of FH subjects achieved their LDL-C targets. Reductions were observed in LDL-C (− 49.8%, p < 0.001), Lp(a) (− 21.4%, p < 0.001), and PWV (Δ − 22.7%, p < 0.001).

Yet, PCSK9's impact on osteoporosis remains unclear. Hence, we employed Mendelian randomization (MR) analysis for examining PCSK9 inhibitor effects on osteoporosis. METHODS: Single nucleotide polymorphisms (SNPs) for 3-hydroxy-3-methylglutaryl cofactor A reductase (HMGCR) and PCSK9 were gathered from available online databases for European pedigrees. Four osteoporosis-related genome-wide association studies (GWAS) data served as the main outcomes, and coronary artery disease (CAD) as a positive control for drug-targeted MR analyses. The results of MR analyses examined by sensitivity analyses were incorporated into a meta-analysis for examining causality between PCSK9 and HMGCR inhibitors and osteoporosis. RESULTS: The meta-analysis involving a total of 1,263,102 subjects, showed that PCSK9 inhibitors can increase osteoporosis risk (P < 0.05, I 2 , 39%).

PCSK9 inhibitors have been shown to remarkably reduce cardiovascular events in patients at high risk, but data on their impact on sudden cardiac death (SCD) and ventricular arrhythmias are limited. This study aimed to evaluate whether PCSK9 inhibitor therapy reduces the risk of SCD and ventricular arrhythmias. METHODS: PubMed and Embase were searched up to September 1, 2024 and combined with data from ClinicalTrials.gov. Randomized controlled trials of PCSK9 inhibitors with ≥ 450 patients and follow-up of ≥ 48 weeks were considered for inclusion. Primary outcomes were the incidence of SCD and ventricular arrhythmias. We used a random-effects model to synthesize the data, calculating risk ratio (RR) and 95% confidence intervals (CI). Heterogeneity between studies was assessed with I² statistics. Risk of bias was assessed using the Cochrane risk of bias tool. RESULTS: A total of 12 articles with 16 trials involving 90,764 patients were included. The follow-up duration ranged from 48 weeks to 3.4 years."},{"source_id":"source_21","study":"Effectiveness of PCSK9 inhibitors: A Target Trial Emulation framework based on Real-World Electronic Health Records","doi":"10.1371/journal.pone.0309470","url":"https://doi.org/10.1371/journal.pone.0309470","support_kind":"bundle_reference","cited_as":"Barbati 2024","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"Inhibition of PCSK9 by the use of monoclonal antibodies has been demonstrated to significantly reduce LDL values (Low-Density Lipoprotein) by 50-70%, regardless of the therapeutic background in which it is implemented (monotherapy or in combination with the standard Lipid-Lowering Therapy, LLT) [ 6 ].

In the last years, Proprotein Convertase Subtilisin-Kexin type 9 inhibitors (PCSK9-i) has emerged as a key therapeutic target to lower LDL and were introduced for prevention of CV events. Recently (June 2022) the Italian Medicines Agency (AIFA) modified the eligibility criteria for the use of PCSK9-i. We designed an observational study to estimate the prevalence of eligible subjects and evaluate the effectiveness of PCSK9-i applying a Target Trial Emulation (TTE) approach based on Electronic Health Records (EHR). Subjects meeting the eligibility criteria were identified from July 2017 (when PCSK9-i became available) to December 2020. Outcomes were all-cause death and the first hospitalization. Among eligible subjects, we identified those treated at date of the first prescription.

We assessed the cognitive function in patients initiating PCSK9i, and differences in cognitive function domains, to analyze subgroups by the low-density lipoprotein cholesterol (LDL-C) achieved, and differences between alirocumab and evolocumab. METHODS: This has a multicenter, quasi-experimental design carried out in 12 Spanish hospitals from May 2020 to February 2023. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). RESULTS: Among 158 patients followed for a median of 99 weeks, 52% were taking evolocumab and 48% alirocumab; the mean change from baseline in MoCA score at follow-up was + 0.28 [95% CI (- 0.17 to 0.73; p = 0.216)].

Therefore, this study aims to assess the effect of PCSK9 inhibitors (alirocumab and evolocumab) on ASCVD patients considering the number needed to treat (NNT). METHODS: We reviewed randomized controlled trials (RCTs) which compared the effects of alirocumab or evolocumab and placebo or standards of care. All articles were published in English up to May 2022. Using random effect models, we estimated risk ratios (RRs), NNT, and 95% confidence intervals (CI). RESULTS: We incorporated 12 RCTs with 53 486 patients total, of which 27 674 received PCSK9 inhibitors and 25 812 received placebos. The mean follow-up duration was 1.56 years. The effect of PCSK9 inhibitors on major adverse cardiovascular events (MACE) was statistically significant, and the corresponding mean NNT was 36.

However, it remains unclear which monotherapy offers greater cardiovascular benefit. METHODS: This prospective non-randomized real-world observational cohort study enrolled coronary heart disease inpatients from July 2020 to March 2024. Patients received either alirocumab (75 mg/2 weeks) or statins (atorvastatin 20 mg/day or rosuvastatin 10 mg/day). The primary outcome was a composite of cardiovascular death, myocardial infarction, stroke, heart failure hospitalization, or coronary revascularization. Cox proportional hazards models and restricted mean survival time analyses were used. RESULTS: Among 1165 analyzed patients, 215 received PCSK9 inhibitors and 950 received statins. After 1 month, low-density lipoprotein cholesterol reduction was greater in the PCSK9 inhibitor group (from 2.57 to 0.75 mmol/L) than in the statin group (from 2.29 to 1.40 mmol/L; P <0.001).

AIS frequently coexists with coronary heart disease (CHD), complicating treatment and leading to more severe symptoms and worse outcomes. Shared risk factors between CHD and AIS, especially elevated low-density lipoprotein cholesterol (LDL-C), contribute to atherosclerosis and inflammation, which worsen brain tissue damage. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors offer a promising treatment option. They effectively lower LDL-C levels and may help reduce END in AIS patients with CHD. This study aims to evaluate how effective PCSK9 inhibitors are in reducing END among this high-risk group and to provide new insights for treatment strategies.

It is commonly acknowledged that low-density lipoprotein (LDL) is a major cause of ASCVD. Several online databases and search engines, such as Pub- Med and the Cochrane Library, were used to conduct a thorough search. METHODS: This study included RCTs assessing the effect of PCSK9 inhibitors on cardiovascular events. The RevMan 5.4 software was used to conduct the meta-analysis. This analysis included nine RCTs in total. RESULTS: Meta-analysis of the included studies showed that the levels of total cholesterol, LDL, and triglycerides were reduced after the use of PCSK9 inhibitors, and HDL levels were increased, which is good cholesterol. Most adverse cardiac events (MACE) were reduced after the use of PCSK9 inhibitors. CONCLUSION: In conclusion, ezetimibe, a PCSK9 inhibitor added to statin therapy, further reduces MACE risk without affecting all-cause mortality, even though statins already significantly reduce major adverse cardiovascular events (MACE) and mortality."},{"source_id":"source_28","study":"Safety and Effectiveness of PCSK9 Inhibitors and Inclisiran in Patients With Neuromuscular Disorders and Statin Intolerance","doi":"10.1111/ene.70175","url":"https://doi.org/10.1111/ene.70175","support_kind":"bundle_reference","cited_as":"Theodorou 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"PCSK9 inhibitors and inclisiran have been studied in patients with homozygous or heterozygous familial hypercholesterolemia, atherosclerotic cardiovascular disease (ASCVD), and ASCVD risk equivalent (a high‐risk primary prevention cohort comprising individuals with type 2 diabetes mellitus, familial hypercholesterolemia, or a 10‐year risk of a CV event ≥ 20% [by Framingham Risk Score or equivalent]).

We assessed the safety and efficacy of PCSK9 inhibitors and inclisiran in this specific patient subgroup. METHODS: We conducted an observational cohort study evaluating patients with available clinical and laboratory data prior to and at prespecified time points following treatment initiation with PCSK9 inhibitors or inclisiran. RESULTS: Eleven patients with neuromuscular disorders and statin intolerance were included in this study. Median follow-up time after PCSK9 inhibitor or inclisiran initiation was 14 (9-17) months. PCSK9 inhibitors or inclisiran use led to a significant decrease in mean low-density lipoprotein cholesterol levels. Moreover, all patients tolerated these lipid-lowering agents without exacerbation of their underlying myositis, myopathy, neuromuscular junction disorder, and without presenting any adverse event or relapse of myotoxicity and/or hepatotoxicity."},{"source_id":"source_29","study":"Beyond maximally tolerated statins: PCSK9 inhibitors as a critical adjunct for cardiovascular risk reduction in peripheral artery disease-a systematic review and meta-analysis.","doi":"10.1080/03007995.2026.2662127","url":"https://doi.org/10.1080/03007995.2026.2662127","support_kind":"bundle_reference","cited_as":"Ariyanti 2026","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"PCSK9 inhibitors significantly reduced MACE (HR 0.77; 95% CI: 0.65 to 0.92) and lowered LDL-C levels (MD -55.76 mg/dL; 95% CI: -63.19 to -48.34).

This meta-analysis aimed to evaluate their effects on cardiovascular, functional, limb, and survival outcomes in PAD. METHODS: We systematically searched PubMed, Scopus, and ClinicalTrials.gov through August 2025 for RCTs and cohort studies comparing PCSK9 inhibitors with placebo or standard therapy in PAD. Primary outcomes were MACE and major amputation. Data were analyzed using fixed- or random-effects models depending on heterogeneity. RESULTS: Six studies (five RCTs, one cohort) involving 4,563 patients were included. PCSK9 inhibitors significantly reduced MACE (HR 0.77; 95% CI: 0.65 to 0.92) and lowered LDL-C levels (MD -55.76 mg/dL; 95% CI: -63.19 to -48.34). Positive but non-significant trends were observed for major amputation (HR 0.35; 95% CI: 0.11 to 1.07), all-cause mortality (HR 0.58; 95% CI: 0.26 to 1.30), and walking performance (SMD 2.38; 95% CI: -1.97 to 6.73)."},{"source_id":"source_30","study":"Effect of PCSK9 inhibitors on major cardiac adverse events and lipoprotein-a in patients with coronary heart disease: a meta-analysis.","doi":"10.1097/mca.0000000000001464","url":"https://doi.org/10.1097/mca.0000000000001464","support_kind":"bundle_reference","cited_as":"Hu 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"The results showed that compared with the control group, PCSK9 inhibitors significantly reduced low-density lipoprotein cholesterol (WMD = -1.24 mmol/L, 95% confidence interval (CI): -1.28 to -1.20), total cholesterol, triglycerides, and Lp(a) levels while increasing high-density lipoprotein cholesterol levels.

Monoclonal antibodies that inhibit proprotein convertase subtilisin-kexin type 9 (PCSK9) reduce low-density lipoprotein (LDL) cholesterol levels and subsequently the risk of cardiovascular events in patients with dyslipidaemia. There are no published data on the effect of this medication class on cholesterol levels in patients after cardiac transplantation. METHODS: In this retrospective study we investigated patients who were treated with PCSK9 inhibitors either because of intolerance of statins or residual hypercholesterolaemia with evidence of cardiac allograft vasculopathy. We compared the data of patients prior to the start with these medications with their most recent dataset. RESULTS: Ten patients (nine men; mean age 58±6 years) underwent cardiac transplantation 8.3±4.5 (range 3-15) years ago. The treatment duration of Evolocumab or Alirocumab was on average 296±125 days and lead to a reduction of total Cholesterol (281±52 mg/dl to 197±36 mg/dl; p = 0.002) and LDL Cholesterol (170±22 mg/dl to 101±39 mg/dl; p = 0.001)."},{"source_id":"source_33","study":"Proprotein convertase subtilisin/kexin 9 inhibitors in reducing cardiovascular outcomes: a systematic review and meta-analysis.","doi":"10.1136/heartjnl-2019-314763","url":"https://doi.org/10.1136/heartjnl-2019-314763","support_kind":"bundle_reference","cited_as":"Du 2019","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Dichotomous variables from individual studies were pooled by relative risks (RR) and their 95% CIs using the random-effect model.

Design Bayesian network meta-analysis was conducted to compare treatment groups. Methods Thirty-nine randomized controlled trials were selected using MEDLINE, EMBASE, and CENTRAL (inception - September 2017). Results In network meta-analysis of 189,116 patients, PCSK9 inhibitors were ranked as the best treatment for prevention of major adverse cardiovascular events (Surface Under Cumulative Ranking Curve (SUCRA), 85%), myocardial infarction (SUCRA, 84%) and stroke (SUCRA, 80%). PCSK9 inhibitors reduced the risk of major adverse cardiovascular events compared with ezetimibe + statin (odds ratio (OR): 0.72; 95% credible interval (CrI), 0.55-0.95; Grading of Recommendation Assessment, Development and Evaluation (GRADE) criteria: moderate), statin (OR: 0.78; 95% CrI: 0.62-0.97; GRADE: moderate) and placebo (OR: 0.63; 95% CrI: 0.49-0.79; GRADE: high). The PCSK9 inhibitors were consistently superior to groups for major adverse cardiovascular event reduction in secondary prevention trials (SUCRA, 95%)."},{"source_id":"source_35","study":"Cardiovascular Efficacy and Safety of PCSK9 Inhibitors: Systematic Review and Meta-analysis Including the ODYSSEY OUTCOMES Trial.","doi":"10.1016/j.cjca.2018.04.002","url":"https://doi.org/10.1016/j.cjca.2018.04.002","support_kind":"bundle_reference","cited_as":"Turgeon 2018","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"We systematically reviewed and meta-analyzed randomized controlled trials with durations ≥ 6 months comparing MACE, mortality, and safety with PCSK9 inhibitors vs control.

Therefore, additional LDL-C reduction may be warranted, especially for patients who are unresponsive to, or unable to take, existing LDL-C-reducing therapies. By inhibiting the proprotein convertase subtilisin/kexin type 9 (PCSK9) enzyme, monoclonal antibodies (PCSK9 inhibitors) may further reduce LDL-C, potentially reducing CVD risk as well. OBJECTIVES: Primary To quantify short-term (24 weeks), medium-term (one year), and long-term (five years) effects of PCSK9 inhibitors on lipid parameters and on the incidence of CVD. Secondary To quantify the safety of PCSK9 inhibitors, with specific focus on the incidence of type 2 diabetes, cognitive function, and cancer. Additionally, to determine if specific patient subgroups were more or less likely to benefit from the use of PCSK9 inhibitors.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included."},{"source_id":"source_2","study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","support_kind":"bundle_reference","cited_as":"Hollstein 2021","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group."},{"source_id":"source_3","study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","support_kind":"bundle_reference","cited_as":"Imran 2023","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05)."},{"source_id":"source_5","study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","support_kind":"bundle_reference","cited_as":"Rehues 2023","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

While proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors effectively diminish LDL-C levels, their combined use with statins for reducing major adverse cardiovascular events (MACE) and improving lipid profiles post-PCI requires further validation. This study seeks to appraise the therapeutic impact of PCSK9 inhibitors combined with statins on MACE and blood lipids in patients following PCI. METHODS: Randomized controlled trials (RCTs) and cohort studies as of February 2025 in the PubMed, Embase, Cochrane Library, and Web of Science databases were identified. Regarding the risk of bias evaluation, Cochrane ROB 2.0 was employed for RCTs. Moreover, cohort studies were appraised by means of the Newcastle-Ottawa Scale. In terms of heterogeneity, it was appraised by means of the I 2 statistics.

However, there remained a dearth of direct comparative studies among different PCSK9 inhibitors. Therefore, this study aimed to conduct a network meta-analysis to evaluate the efficacy and safety of different PCSK9 inhibitors combined with statins. METHODS: A comprehensive literature search was conducted from the study's inception to 12 November 2023, encompassing multiple online databases including PubMed, Embase, Cochrane Central, Web of Science, and ClinicalTrials.gov to obtain relevant randomized controlled trials. Frequentist network meta-analysis was employed to compare the efficacy and safety of different PCSK9 inhibitors. The efficacy endpoints were low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB), and lipoprotein (a) (Lp(a)). The safety endpoints were any adverse events (AE), severe adverse events (SAE), AE leading to treatment discontinuation, and injection-site reaction. RESULTS: Compared with placebo and ezetimibe, all PCSK9 inhibitors demonstrated significant reductions in LDL-C levels."},{"source_id":"source_8","study":"Effect of PCSK9 inhibitors on the quality of life in patients with acute coronary syndromes — exploratory analysis of the EMSIACS trial","doi":"10.1038/s41598-025-26495-y","url":"https://doi.org/10.1038/s41598-025-26495-y","support_kind":"bundle_reference","cited_as":"Jing 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"At week 12, Evolocumab significantly improved Global Physical Health (GPH) ( P < 0.001) and Global Mental Health (GMH) scores ( P < 0.001), particularly in pain intensity, mental health, and social activity satisfaction ( P < 0.001).

This study examined the impact of PCSK9i on quality of life in ACS patients, comparing PCSK9i plus statin versus statin-only therapy using PROMIS-10, and analyzed the association between PROMIS scores and major adverse cardiovascular events (MACE). The EMSIACS trial is a prospective, randomized, open-label, parallel-group, multicenter study registered at ClinicalTrials.gov (NCT04100434). This paper presents the exploratory outcomes of this trial. From September 2020 to March 2022, a total of 500 ACS patients were enrolled. Patients were randomly assigned in a 1:1 ratio to receive Evolocumab plus statin therapy or statin-only therapy. The quality of life was assessed using PROMIS 10 at baseline, week 12, and week 48. PROMIS 10 includes two summary scores: Global Physical Health (GPH, including physical health, physical function, fatigue and pain intensity) and Global Mental Health (GMH, including overall quality of life, mental health, satisfaction with social activities, and emotional problems)."},{"source_id":"source_9","study":"Efficacy of PCSK9 Inhibitors on Clinical Outcomes in Patients with Established Atherosclerotic Cardiovascular Disease: A Network Meta-analysis","doi":"10.1007/s40256-025-00778-1","url":"https://doi.org/10.1007/s40256-025-00778-1","support_kind":"bundle_reference","cited_as":"Raone 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Evolocumab (140 mg every 2 weeks or 420 mg monthly) and alirocumab 150 mg every 2 weeks significantly reduced MACE compared with placebo (risk ratios (RR): 0.78, 95% confidence intervals (CI): 0.66-0.93 and RR: 0.47, 95% CI 0.25-0.86, respectively).

Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i), including monoclonal antibodies and small-interfering RNA agents, offer additional risk reduction, yet comparative evidence across individual regimens remains limited. METHODS AND RESULTS: We conducted a systematic review and network meta-analysis of randomized controlled trials evaluating approved PCSK9i dosages in patients with ASCVD. The primary outcome was major adverse cardiovascular events (MACE); the secondary outcomes included myocardial infarction, stroke, coronary revascularization, cardiovascular mortality, and all-cause death. A total of eight trials involving 49,847 patients were included. Evolocumab (140 mg every 2 weeks or 420 mg monthly) and alirocumab 150 mg every 2 weeks significantly reduced MACE compared with placebo (risk ratios (RR): 0.78, 95% confidence intervals (CI): 0.66-0.93 and RR: 0.47, 95% CI 0.25-0.86, respectively).

This study aimed to evaluate the efficacy and safety of PCSK9 inhibitors for ACS patients. METHODS: We searched the following databases until March 2023: PubMed, Embase, Cochrane, Web of Science, CNKI, Chongqing VIP Database and Wan Fang Database. Finally, all randomized controlled trials, retrospective studies and prospective studies were included in the analysis. RESULTS: A total of 20 studies involving 48,621 patients were included in this meta-analysis. The results demonstrated that PCSK9 inhibitors group was more beneficial for ACS patients compared to control group (receiving statins alone or placebo). The meta-analysis showed: there was no significant difference in high density lipoprotein cholesterol between PCSK9 inhibitors group and control group (standard mean difference = 0.17, 95% confidence interval [CI]: -0.02 to 0.36, P = ."},{"source_id":"source_11","study":"Efficacy and Safety of Evolocumab and Alirocumab as PCSK9 Inhibitors in Pediatric Patients with Familial Hypercholesterolemia: A Systematic Review and Meta-Analysis","doi":"10.3390/medicina60101646","url":"https://doi.org/10.3390/medicina60101646","support_kind":"bundle_reference","cited_as":"Xiao 2024","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Pooled results showed significant efficacy of evolocumab/alirocumab in reducing low-density lipoprotein cholesterol (LDL-C) (weighted mean difference [WMD]: -37.92%, 95% confidence interval [CI]: -43.06% to -32.78%; I 2 = 0.0%, p = 0.60), apolipoprotein B (WMD: -33.67%, 95% CI: -38.12% to -29.22%; I 2 = 0.0%, p = 0.71), and also lipoprotein(a) (WMD: -16.94%, 95% CI: -26.20% to -7.69%; I 2 = 0.0%, p = 0.71) among pediatric patients with FH.

This meta-analysis is aimed at updating the safety data of PCSK9 inhibitors. METHODS: We assessed the relative risk for all treatment-related adverse events, serious adverse events, diabetes-related adverse events, and neurocognitive and neurologic adverse events with PCSK9 inhibitors compared to controls (placebo or ezetimibe). In addition, we conducted a meta-analysis to quantitatively integrate and estimate the adverse event rates in long-term studies. RESULTS: There were no significant differences between PCSK9 inhibitors and controls in the relative risk analysis. In a subgroup analysis of each PCSK9 inhibitor, alirocumab treatment significantly reduced the risk of serious adverse events compared to control treatment (risk ratio (RR) = 0.937; 95% confidence interval (CI), 0.896-0.980), but no significant difference was observed with evolocumab treatment (RR = 1.003; 95% CI, 0.963-1.054)."},{"source_id":"source_13","study":"PCSK9 inhibitors for secondary prevention in patients with cardiovascular diseases: a bayesian network meta-analysis","doi":"10.1186/s12933-022-01542-4","url":"https://doi.org/10.1186/s12933-022-01542-4","support_kind":"bundle_reference","cited_as":"Wang 2022a","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"The use of alirocumab was associated with reductions in all-cause mortality compared with control (RR 0.83, 95% CrI 0.72-0.95).

However, evidence of the optimal PCSK9 agents targeting PCSK9 for secondary prevention in patients with high-risk of cardiovascular events is lacking. Therefore, this study was conducted to evaluate the benefit and safety of different types of PCSK9 inhibitors. METHODS: Several databases including Cochrane Central, Ovid Medline, and Ovid Embase were searched from inception until March 30, 2022 without language restriction. Randomized controlled trials (RCTs) comparing administration of PCSK9 inhibitors with placebo or ezetimibe for secondary prevention of cardiovascular events in patients with statin-background therapy were identified. The primary efficacy outcome was all-cause mortality. The primary safety outcome was serious adverse events. RESULTS: Overall, nine trials totaling 54,311 patients were identified. Three types of PCSK9 inhibitors were evaluated. The use of alirocumab was associated with reductions in all-cause mortality compared with control (RR 0.83, 95% CrI 0.72-0.95)."},{"source_id":"source_14","study":"Lipid-Lowering Efficacy and Safety of Oral Proprotein Convertase Subtilisin/Kexin Type 9 Inhibitors: A Systematic Review and Meta-Analysis","doi":"10.1007/s12325-025-03418-x","url":"https://doi.org/10.1007/s12325-025-03418-x","support_kind":"bundle_reference","cited_as":"Masson 2026","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Compared with placebo, oral PCSK9 inhibitors significantly reduced LDL-C [mean difference (MD) - 55.7; 95% confidence interval (CI) - 59.3 to - 52.1; I 2 = 14%)] and apolipoprotein B (MD - 46.9; 95% CI - 54.6 to - 39.2; I 2 = 72.9%).

Recently, novel oral PCSK9 inhibitors have emerged, providing new evidence regarding their lipid-lowering efficacy and safety. METHODS: This systematic review and meta-analysis was conducted in accordance with PRISMA guidelines. Randomized clinical trials evaluating oral PCSK9 inhibitors and reporting percentage changes in lipid parameters and/or adverse events were included. A qualitative synthesis was performed for all studies meeting predefined eligibility criteria, followed by a quantitative synthesis of studies with sufficient data for statistical pooling. RESULTS: Seven randomized clinical trials were included in the qualitative analysis, of which four were eligible for meta-analysis. Five oral PCSK9 inhibitors were identified. Three agents (MK-0616, AZD0780, and NNC0385-0434) contributed to the quantitative analysis, while two (DC371739 and CVI-LM001) were assessed descriptively."},{"source_id":"source_15","study":"PCSK9 inhibitoRs for Early Passivation of coRonary athEroSclerotic plaqueS in acute coronary syndromes (REPRESS): study protocol for a multicentre randomised controlled trial","doi":"10.1136/bmjopen-2025-112947","url":"https://doi.org/10.1136/bmjopen-2025-112947","support_kind":"bundle_reference","cited_as":"Chen 2026","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"direct","quote":"The primary endpoint will be analysed using analysis of covariance, adjusting for treatment group, baseline LDL-C stratification (≥1.8 vs <1.8 mmol/L), and baseline minimum FCT. 1 Because non-culprit plaques are prone to rupture and thrombosis, patients with ACS remain at elevated risk of recurrent cardiovascular events, especially during the first 30 to 90 days after discharge.","evidence_span":"The background evidence for pcsk9 inhibitors effects is heterogeneous rather than uniformly confirmatory.

Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are increasingly used alongside statins to achieve guideline-recommended LDL-C targets after ACS. However, despite substantial LDL-C reductions with early PCSK9i initiation, their effects on non-culprit coronary atherosclerotic plaques remain unclear. This study aims to assess the impact of early intensive LDL-C lowering with PCSK9i added to moderate-intensity statin therapy on optical coherence tomography (OCT)-derived plaque characteristics in non-culprit coronary lesions in patients with ACS. METHODS AND ANALYSIS: In this prospective, multicentre, open-label trial, 212 patients with ACS will be randomised 1:1 to an early intensified lipid-lowering strategy (PCSK9i added to moderate-intensity statin) or guideline-directed medical therapy for 6 months. Serial OCT imaging of non-culprit coronary arteries with 20-70% stenosis will be performed at baseline and 6 months."},{"source_id":"source_16","study":"Efficacy and safety of PCSK9 inhibitors, potent statins, and their combinations for reducing low-density lipoprotein cholesterol in hyperlipidemia patients: a systematic network meta-analysis","doi":"10.3389/fcvm.2024.1415668","url":"https://doi.org/10.3389/fcvm.2024.1415668","support_kind":"bundle_reference","cited_as":"Jiang 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Meanwhile, compared with placebo, evolocumab (MD -1.89, 95% CI -2.27 to -1.50), alirocumab (MD -1.83, 95% CI -2.09 to -1.57), rosuvastatin (MD -1.93, 95% CI -2.30 to -1.56), inclisiran (MD -1.68, 95% CI -2.10 to -1.27), and atorvastatin (MD -1.68, 95% CI -2.04 to -1.31) could also play a role in the treatment of LDL-C reduction.

METHODS: A systematic search was conducted across databases including PubMed, Embase, and the Cochrane Library to explore lipid-lowering therapies in hyperlipidemia from their inception to 7 November 2023. A network meta-analysis (NMA) was conducted via Stata 17 software, with two authors independently conducting the search, screening, and data abstraction. RESULTS: A total of 68 clinical studies involving 21,288 patients with hyperlipidemia were incorporated into the NMA. PSCK9 inhibitors and potent statins significantly reduced LDL-C levels from baseline vs. placebo regardless of background therapy.

METHODS: The databases EMBASE, PubMed, Web of Science, Cochrane, and ClinicalTrials.gov were thoroughly searched without any restrictions on language. Review Manager 5.3 software was utilized to calculate relative risks with 95% confidence intervals (CIs) for dichotomous data and mean differences or standardized mean differences with 95%CIs for continuous data. To evaluate publication bias, Egger's test was employed using Stata/SE software. RESULTS: This analysis included 26 studies comprising 28 randomized controlled trials (RCTs) involving a total of 100,193 patients, and 4 different lipid-lowering therapy combinations. For events with creatine kinase >3ULN, evolocumab and alirocumab demonstrated significant advantages compared to inclisiran.

PCSK9 inhibitors (PCSK9i) reduce LDL-C and Lp(a), however, the effect of dual lipid reduction on mechanical vascular function remains unclear. The aim of this study was to evaluate the efficacy of PCSK9i in reducing LDL-C and Lp(a) and to assess the relationship between the dual lipid reduction and the mechanical vascular profile improvement in FH subjects. METHODS: This prospective observational study included 301 genetically confirmed FH subjects treated with PCSK9i added to high-intensity statins and ezetimibe. Biochemical and PWV measurements were performed at baseline and after six months. Subjects were stratified into four groups based on median values of ΔLDL-C and ΔLp(a). RESULTS: After six months of add-on PCSK9i, 44.9% of FH subjects achieved their LDL-C targets. Reductions were observed in LDL-C (− 49.8%, p < 0.001), Lp(a) (− 21.4%, p < 0.001), and PWV (Δ − 22.7%, p < 0.001).

Yet, PCSK9's impact on osteoporosis remains unclear. Hence, we employed Mendelian randomization (MR) analysis for examining PCSK9 inhibitor effects on osteoporosis. METHODS: Single nucleotide polymorphisms (SNPs) for 3-hydroxy-3-methylglutaryl cofactor A reductase (HMGCR) and PCSK9 were gathered from available online databases for European pedigrees. Four osteoporosis-related genome-wide association studies (GWAS) data served as the main outcomes, and coronary artery disease (CAD) as a positive control for drug-targeted MR analyses. The results of MR analyses examined by sensitivity analyses were incorporated into a meta-analysis for examining causality between PCSK9 and HMGCR inhibitors and osteoporosis. RESULTS: The meta-analysis involving a total of 1,263,102 subjects, showed that PCSK9 inhibitors can increase osteoporosis risk (P < 0.05, I 2 , 39%). However, HMGCR inhibitors are not associated with osteoporosis risk."},{"source_id":"source_20","study":"Evaluating the potential effect of PCSK9 inhibitors on the risk of sudden cardiac death and ventricular arrhythmias: A meta-analysis of randomized controlled trials","doi":"10.1371/journal.pone.0329676","url":"https://doi.org/10.1371/journal.pone.0329676","support_kind":"bundle_reference","cited_as":"Zhang 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Randomized controlled trials of PCSK9 inhibitors with ≥ 450 patients and follow-up of ≥ 48 weeks were considered for inclusion.

PCSK9 inhibitors have been shown to remarkably reduce cardiovascular events in patients at high risk, but data on their impact on sudden cardiac death (SCD) and ventricular arrhythmias are limited. This study aimed to evaluate whether PCSK9 inhibitor therapy reduces the risk of SCD and ventricular arrhythmias. METHODS: PubMed and Embase were searched up to September 1, 2024 and combined with data from ClinicalTrials.gov. Randomized controlled trials of PCSK9 inhibitors with ≥ 450 patients and follow-up of ≥ 48 weeks were considered for inclusion. Primary outcomes were the incidence of SCD and ventricular arrhythmias. We used a random-effects model to synthesize the data, calculating risk ratio (RR) and 95% confidence intervals (CI). Heterogeneity between studies was assessed with I² statistics. Risk of bias was assessed using the Cochrane risk of bias tool. RESULTS: A total of 12 articles with 16 trials involving 90,764 patients were included.

In the last years, Proprotein Convertase Subtilisin-Kexin type 9 inhibitors (PCSK9-i) has emerged as a key therapeutic target to lower LDL and were introduced for prevention of CV events. Recently (June 2022) the Italian Medicines Agency (AIFA) modified the eligibility criteria for the use of PCSK9-i. We designed an observational study to estimate the prevalence of eligible subjects and evaluate the effectiveness of PCSK9-i applying a Target Trial Emulation (TTE) approach based on Electronic Health Records (EHR). Subjects meeting the eligibility criteria were identified from July 2017 (when PCSK9-i became available) to December 2020. Outcomes were all-cause death and the first hospitalization. Among eligible subjects, we identified those treated at date of the first prescription. Inverse Probability of Treatment Weights (IPTW) were estimated including demographic and clinical covariates, history of treatment with statins and the month/year eligibility date."},{"source_id":"source_22","study":"Cognitive Function with PCSK9 Inhibitors: A 24-Month Follow-Up Observational Prospective Study in the Real World—MEMOGAL Study","doi":"10.1007/s40256-023-00604-6","url":"https://doi.org/10.1007/s40256-023-00604-6","support_kind":"bundle_reference","cited_as":"Seijas-Amigo 2023","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"Alirocumab and evolocumab are the first class of PCSK9i that demonstrated in randomized clinical trials the ability to reduce the LDL-C levels by about 60% [ 9 , 10 ].

We assessed the cognitive function in patients initiating PCSK9i, and differences in cognitive function domains, to analyze subgroups by the low-density lipoprotein cholesterol (LDL-C) achieved, and differences between alirocumab and evolocumab. METHODS: This has a multicenter, quasi-experimental design carried out in 12 Spanish hospitals from May 2020 to February 2023. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). RESULTS: Among 158 patients followed for a median of 99 weeks, 52% were taking evolocumab and 48% alirocumab; the mean change from baseline in MoCA score at follow-up was + 0.28 [95% CI (- 0.17 to 0.73; p = 0.216)].

Therefore, this study aims to assess the effect of PCSK9 inhibitors (alirocumab and evolocumab) on ASCVD patients considering the number needed to treat (NNT). METHODS: We reviewed randomized controlled trials (RCTs) which compared the effects of alirocumab or evolocumab and placebo or standards of care. All articles were published in English up to May 2022. Using random effect models, we estimated risk ratios (RRs), NNT, and 95% confidence intervals (CI). RESULTS: We incorporated 12 RCTs with 53 486 patients total, of which 27 674 received PCSK9 inhibitors and 25 812 received placebos. The mean follow-up duration was 1.56 years. The effect of PCSK9 inhibitors on major adverse cardiovascular events (MACE) was statistically significant, and the corresponding mean NNT was 36. Alirocumab reduced the risk of MACE, stroke, and coronary revascularization; the corresponding mean NNT were 37, 319, and 107, respectively."},{"source_id":"source_24","study":"PCSK9 inhibitors in the management of hypercholesterolaemia after heart transplantation in the UK, a single centre observational study","doi":"10.1038/s41598-025-22916-0","url":"https://doi.org/10.1038/s41598-025-22916-0","support_kind":"bundle_reference","cited_as":"Akhtar 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"Estimated treatment effects constant over time expects to reduce LDL by about 2.19 to 2.77 mmol/L with 95% probability.

However, it remains unclear which monotherapy offers greater cardiovascular benefit. METHODS: This prospective non-randomized real-world observational cohort study enrolled coronary heart disease inpatients from July 2020 to March 2024. Patients received either alirocumab (75 mg/2 weeks) or statins (atorvastatin 20 mg/day or rosuvastatin 10 mg/day). The primary outcome was a composite of cardiovascular death, myocardial infarction, stroke, heart failure hospitalization, or coronary revascularization. Cox proportional hazards models and restricted mean survival time analyses were used. RESULTS: Among 1165 analyzed patients, 215 received PCSK9 inhibitors and 950 received statins. After 1 month, low-density lipoprotein cholesterol reduction was greater in the PCSK9 inhibitor group (from 2.57 to 0.75 mmol/L) than in the statin group (from 2.29 to 1.40 mmol/L; P <0.001).

AIS frequently coexists with coronary heart disease (CHD), complicating treatment and leading to more severe symptoms and worse outcomes. Shared risk factors between CHD and AIS, especially elevated low-density lipoprotein cholesterol (LDL-C), contribute to atherosclerosis and inflammation, which worsen brain tissue damage. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors offer a promising treatment option. They effectively lower LDL-C levels and may help reduce END in AIS patients with CHD. This study aims to evaluate how effective PCSK9 inhibitors are in reducing END among this high-risk group and to provide new insights for treatment strategies.

It is commonly acknowledged that low-density lipoprotein (LDL) is a major cause of ASCVD. Several online databases and search engines, such as Pub- Med and the Cochrane Library, were used to conduct a thorough search. METHODS: This study included RCTs assessing the effect of PCSK9 inhibitors on cardiovascular events. The RevMan 5.4 software was used to conduct the meta-analysis. This analysis included nine RCTs in total. RESULTS: Meta-analysis of the included studies showed that the levels of total cholesterol, LDL, and triglycerides were reduced after the use of PCSK9 inhibitors, and HDL levels were increased, which is good cholesterol. Most adverse cardiac events (MACE) were reduced after the use of PCSK9 inhibitors. CONCLUSION: In conclusion, ezetimibe, a PCSK9 inhibitor added to statin therapy, further reduces MACE risk without affecting all-cause mortality, even though statins already significantly reduce major adverse cardiovascular events (MACE) and mortality."},{"source_id":"source_28","study":"Safety and Effectiveness of PCSK9 Inhibitors and Inclisiran in Patients With Neuromuscular Disorders and Statin Intolerance","doi":"10.1111/ene.70175","url":"https://doi.org/10.1111/ene.70175","support_kind":"bundle_reference","cited_as":"Theodorou 2025","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"indirect","quote":"PCSK9 inhibitors and inclisiran have been studied in patients with homozygous or heterozygous familial hypercholesterolemia, atherosclerotic cardiovascular disease (ASCVD), and ASCVD risk equivalent (a high‐risk primary prevention cohort comprising individuals with type 2 diabetes mellitus, familial hypercholesterolemia, or a 10‐year risk of a CV event ≥ 20% [by Framingham Risk Score or equivalent]).

We assessed the safety and efficacy of PCSK9 inhibitors and inclisiran in this specific patient subgroup. METHODS: We conducted an observational cohort study evaluating patients with available clinical and laboratory data prior to and at prespecified time points following treatment initiation with PCSK9 inhibitors or inclisiran. RESULTS: Eleven patients with neuromuscular disorders and statin intolerance were included in this study. Median follow-up time after PCSK9 inhibitor or inclisiran initiation was 14 (9-17) months. PCSK9 inhibitors or inclisiran use led to a significant decrease in mean low-density lipoprotein cholesterol levels. Moreover, all patients tolerated these lipid-lowering agents without exacerbation of their underlying myositis, myopathy, neuromuscular junction disorder, and without presenting any adverse event or relapse of myotoxicity and/or hepatotoxicity."},{"source_id":"source_29","study":"Beyond maximally tolerated statins: PCSK9 inhibitors as a critical adjunct for cardiovascular risk reduction in peripheral artery disease-a systematic review and meta-analysis.","doi":"10.1080/03007995.2026.2662127","url":"https://doi.org/10.1080/03007995.2026.2662127","support_kind":"bundle_reference","cited_as":"Ariyanti 2026","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"PCSK9 inhibitors significantly reduced MACE (HR 0.77; 95% CI: 0.65 to 0.92) and lowered LDL-C levels (MD -55.76 mg/dL; 95% CI: -63.19 to -48.34).

This meta-analysis aimed to evaluate their effects on cardiovascular, functional, limb, and survival outcomes in PAD. METHODS: We systematically searched PubMed, Scopus, and ClinicalTrials.gov through August 2025 for RCTs and cohort studies comparing PCSK9 inhibitors with placebo or standard therapy in PAD. Primary outcomes were MACE and major amputation. Data were analyzed using fixed- or random-effects models depending on heterogeneity. RESULTS: Six studies (five RCTs, one cohort) involving 4,563 patients were included.

This meta-analysis was conducted to evaluate the effects of PCSK9 inhibitors on major adverse cardiac events (MACE) and Lp(a) levels in patients with coronary heart disease. METHODS: Randomized controlled trials (RCTs) were systematically searched in PubMed, the Cochrane Library, and other databases. Stata 15.1 software was used for data analysis, and a random- or fixed-effects model was selected based on inter-study heterogeneity. Egger's test was applied to detect publication bias. RESULTS: A total of 12 RCTs were included, involving 48 116 patients with a mean age of 62 years, comprising 65% males and diverse ethnic backgrounds. The results showed that compared with the control group, PCSK9 inhibitors significantly reduced low-density lipoprotein cholesterol (WMD = -1.24 mmol/L, 95% confidence interval (CI): -1.28 to -1.20), total cholesterol, triglycerides, and Lp(a) levels while increasing high-density lipoprotein cholesterol levels."},{"source_id":"source_31","study":"Effect of PCSK9 Inhibitors on Clinical Outcomes in Patients With Hypercholesterolemia: A Meta‐Analysis of 35 Randomized Controlled Trials","doi":"10.1161/JAHA.117.006910","url":"https://doi.org/10.1161/JAHA.117.006910","support_kind":"bundle_reference","cited_as":"Karatasakis 2017","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"direct","quote":"We performed a systematic review and meta‐analysis of randomized controlled trials comparing treatment with and without PCSK9 inhibitors; 35 randomized controlled trials comprising 45 539 patients (mean follow‐up: 85.5 weeks) were included.

Monoclonal antibodies that inhibit proprotein convertase subtilisin-kexin type 9 (PCSK9) reduce low-density lipoprotein (LDL) cholesterol levels and subsequently the risk of cardiovascular events in patients with dyslipidaemia. There are no published data on the effect of this medication class on cholesterol levels in patients after cardiac transplantation. METHODS: In this retrospective study we investigated patients who were treated with PCSK9 inhibitors either because of intolerance of statins or residual hypercholesterolaemia with evidence of cardiac allograft vasculopathy. We compared the data of patients prior to the start with these medications with their most recent dataset. RESULTS: Ten patients (nine men; mean age 58±6 years) underwent cardiac transplantation 8.3±4.5 (range 3-15) years ago. The treatment duration of Evolocumab or Alirocumab was on average 296±125 days and lead to a reduction of total Cholesterol (281±52 mg/dl to 197±36 mg/dl; p = 0.002) and LDL Cholesterol (170±22 mg/dl to 101±39 mg/dl; p = 0.001)."},{"source_id":"source_33","study":"Proprotein convertase subtilisin/kexin 9 inhibitors in reducing cardiovascular outcomes: a systematic review and meta-analysis.","doi":"10.1136/heartjnl-2019-314763","url":"https://doi.org/10.1136/heartjnl-2019-314763","support_kind":"bundle_reference","cited_as":"Du 2019","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Dichotomous variables from individual studies were pooled by relative risks (RR) and their 95% CIs using the random-effect model.

METHODS: Our systematic review included randomised controlled trials if they studied PCSK9 inhibitors in patients for primary and/or secondary prevention of cardiovascular diseases or with hypercholesterolaemia/hyperlipidaemia. Dichotomous variables from individual studies were pooled by relative risks (RR) and their 95% CIs using the random-effect model. Risk difference (RD) in the 10-year frame was also estimated using the pooled RR and the estimated baseline risk using the control group. Grading of Recommendation Assessment, Development and Evaluation was used to assess the quality of evidence. RESULTS: We included 54 trials with 97 910 patients in the analysis. Compared with controls, PCSK9 inhibitors significantly reduced the risk of MACE by 16% (RR, 0.84; 95% CI 0.79 to 0.89; RD: 47 fewer per 1000 vs 286 as the baseline risk; 95% CI 32 to 59 fewer), non-fatal myocardial infarction (MI) by 17% (RR, 0.83; 95% CI 0.74 to 0.93; RD, 35 fewer per 1000 vs 207 as the baseline; 95% CI 13 to 53 fewer) and any stroke by 25% (RR, 0."},{"source_id":"source_34","study":"A Bayesian network meta-analysis of PCSK9 inhibitors, statins and ezetimibe with or without statins for cardiovascular outcomes.","doi":"10.1177/2047487318766612","url":"https://doi.org/10.1177/2047487318766612","support_kind":"bundle_reference","cited_as":"Khan 2018","population":"not extracted","endpoint":"not extracted","effect":"not extracted","directness":"review","quote":"Results In network meta-analysis of 189,116 patients, PCSK9 inhibitors were ranked as the best treatment for prevention of major adverse cardiovascular events (Surface Under Cumulative Ranking Curve (SUCRA), 85%), myocardial infarction (SUCRA, 84%) and stroke (SUCRA, 80%).

Therefore, additional LDL-C reduction may be warranted, especially for patients who are unresponsive to, or unable to take, existing LDL-C-reducing therapies. By inhibiting the proprotein convertase subtilisin/kexin type 9 (PCSK9) enzyme, monoclonal antibodies (PCSK9 inhibitors) may further reduce LDL-C, potentially reducing CVD risk as well. OBJECTIVES: Primary To quantify short-term (24 weeks), medium-term (one year), and long-term (five years) effects of PCSK9 inhibitors on lipid parameters and on the incidence of CVD. Secondary To quantify the safety of PCSK9 inhibitors, with specific focus on the incidence of type 2 diabetes, cognitive function, and cancer. Additionally, to determine if specific patient subgroups were more or less likely to benefit from the use of PCSK9 inhibitors.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials. METHODS: Using Pubmed, Embase, Cochrane Library and clinicaltrials.","source_id":"source_3","support_kind":"candidate_source_row"},{"study":"Effect of PCSK9 inhibitors on pulse wave velocity and monocyte-to-HDL-cholesterol ratio in familial hypercholesterolemia subjects: results from a single-lipid-unit real-life setting","year":2021,"doi":"10.1007/s00592-021-01703-z","url":"https://doi.org/10.1007/s00592-021-01703-z","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Scicali 2021","quote":"Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP). Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0.","source_id":"source_5","support_kind":"candidate_source_row"}]},{"claim_id":"claim_30","claim":"| Evidence domain | Source | Direction | Directness | Tier | Evidence role | Finding |","citation_support":[],"candidate_sources":[{"study":"Early administration of proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors in patients with acute coronary syndrome: a systematic review and meta-analysis","year":2024,"doi":"10.1186/s12872-024-04057-w","url":"https://doi.org/10.1186/s12872-024-04057-w","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Hosseini 2024","quote":"Early PCSK9 inhibitor administration reduced the incidence of MI, ACS hospitalization, and revascularization at 6-18 months post-ACS.

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included.","source_id":"source_1","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68. RESULTS: At baseline, approximately 50% of patients were statin intolerant, and approximately 90% reported a history of cardiovascular disease. LDL-C reductions remained generally unchanged from weeks 4 to 68 in each treatment group.","source_id":"source_2","support_kind":"candidate_source_row"},{"study":"Proprotein convertase subtilisn/kexin type 9 inhibitors and small interfering RNA therapy for cardiovascular risk reduction: A systematic review and meta-analysis","year":2023,"doi":"10.1371/journal.pone.0295359","url":"https://doi.org/10.1371/journal.pone.0295359","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Imran 2023","quote":"Using random-effects models, we pooled the relative risks and 95% CIs and weighted least-squares mean difference in LDL-c levels.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05).","source_id":"source_4","support_kind":"candidate_source_row"},{"study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Acute-phase serum glycoproteins are upregulated in the liver during systemic inflammation, and their role as inflammatory biomarkers is under clinical evaluation. In this observational study, we evaluate the effects of iPCSK9 on glycoproteins (Glyc) A, B and F. Thirty-nine patients eligible for iPCSK9 therapy were enrolled. One sample before and after one to six months of iPCSK9 therapy with alirocumab was obtained from each patient. Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR).

However, only a minority of patients are achieving LDL-C attainment goal at 6 months. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors are on recommended guideline therapy post-ACS if LDL-C goal attainment is not achieved after high-intensity statin (4-6 weeks) and after the addition of ezetimibe if guideline goal attainment is not achieved after an additional 4-6 weeks. Thus, it has been recommended that PCSK9 inhibitors be considered earlier post-ACS. However, the efficacy of early PCSK9 inhibitors initiation in ACS patients remains uncertain. METHODS: This systematic review and meta-analysis was conducted following PRISMA guidelines. Randomized controlled trials (RCTs) and observational studies involving ACS patients who received PCSK9 inhibitors within 48 h of hospitalization were included. Common and random effects models were used to evaluate the pooled effect of early PCSK9 inhibitor administration. Nine RCTs and three cohort studies were included."},{"id":"source_2","type":"source","study":"PCSK9 Inhibitors in a German Single-Center Clinical Practice: Real-World Treatment of Patients at High Cardiovascular Risk Over 68 Weeks","year":2021,"doi":"10.1007/s40256-020-00411-3","url":"https://doi.org/10.1007/s40256-020-00411-3","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Hollstein 2021","quote":"LDL-C reduction was 7.1% greater in patients receiving statins than in those not receiving statins because of statin intolerance ( P < 0.0001).

OBJECTIVES: We assessed the effectiveness and safety of the PCSK9i alirocumab and evolocumab in a single-center clinical practice for up to 68 weeks. METHODS: In this prospective, open-label study conducted in Germany, 635 enrolled patients were treated with alirocumab [75 or 150 mg every 2 weeks (Q2W)] or evolocumab (140 mg Q2W) according to European Society of Cardiology/European Atherosclerosis Society guidelines (low-density lipoprotein cholesterol [LDL-C] > 1.81/2.59 mmol/L (70/100 mg/dL), depending on cardiovascular risk]. Investigators were able to adjust LLTs, including PCSK9i, according to their own clinical judgment. The primary effectiveness endpoint was LDL-C reduction from baseline to week 68.

Atherosclerosis occurs due to accumulation of low-density lipoprotein cholesterol (LDL-c) in the arterial system. Thus, lipid lowering therapy is essential for both primary and secondary prevention. Proprotein convertase subtilisn/kexin type 9 (PCSK9) inhibitors (Evolocumab, Alirocumab) and small interfering RNA (siRNA) therapy (Inclisiran) have been demonstrated to lower LDL-c and ASCVD events in conjunction with maximally tolerated statin therapy. However, the degree of LDL-c reduction and the impact on reducing major adverse cardiac events, including their impact on mortality, remains unclear. OBJECTIVE: The purpose of this study is to examine the effects of PCSK9 inhibitors and small interfering RNA (siRNA) therapy on LDL-c reduction and major adverse cardiac events (MACE) and mortality by conducting a meta-analysis of randomized controlled trials.

Our aim was to evaluate the effect of PCSK9-i on inflammatory biomarkers, neutrophil-to-lymphocyte ratio, monocyte-to-high-density lipoprotein ratio (MHR), and on early atherosclerosis damage analyzed by pulse wave velocity (PWV) in a cohort of FH subjects. METHODS: In this prospective observational study, we evaluated 56 FH subjects on high-intensity statins plus ezetimibe and with an off-target LDL-C. All subjects were placed on PCSK9-i therapy and obtained biochemical analysis as well as PWV evaluation at baseline and after six months of PCSK9-i therapy. RESULTS: After six months of add-on PCSK9-i therapy, only 42.9% of FH subjects attained LDL-C targets. As expected, a significant reduction of LDL-C (- 49.61%, p < 0.001) was observed after PCSK9-i therapy. Neutrophil count (NC) and MHR were reduced by PCSK9-i (-13.82% and -10.47%, respectively, p value for both < 0.05) and PWV significantly decreased after PCSK9-i therapy (- 20.4%, p < 0.05)."},{"id":"source_5","type":"source","study":"PCSK9 Inhibitors Have Apolipoprotein C-III-Related Anti-Inflammatory Activity, Assessed by 1H-NMR Glycoprotein Profile in Subjects at High or very High Cardiovascular Risk","year":2023,"doi":"10.3390/ijms24032319","url":"https://doi.org/10.3390/ijms24032319","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Rehues 2023","quote":"Proprotein convertase subtilisin/kexin type 9 inhibitors (iPCSK9) can reduce low-density lipoprotein (LDL) cholesterol levels by 60%, but there is still no evidence that they can lower markers of systemic inflammation such as high-sensitivity C-reactive protein (hsCRP).

Lipids, apolipoproteins, hsCRP and PCSK9 levels were measured by biochemical analyses, and the lipoprotein and glycoprotein profiles were measured by 1H nuclear magnetic resonance (1H-NMR). The PCSK9 inhibitor reduced total (36.27%, p < 0.001), LDL (55.05%, p < 0.001) and non-high-density lipoprotein (HDL) (45.11%, p < 0.001) cholesterol, apolipoprotein (apo) C-III (10%, p < 0."},{"id":"source_6","type":"source","study":"Effectiveness of combining PCSK9 inhibitors with statins on major adverse cardiovascular events and lipid levels in patients after percutaneous coronary intervention: a systematic review and meta-analysis","year":2025,"doi":"10.3389/fcvm.2025.1612095","url":"https://doi.org/10.3389/fcvm.2025.1612095","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Cao 2025","quote":"The relative risk (RR) and 95% confidence interval (CI) for dichotomous variables, along with the weighted mean difference (WMD), standardized mean difference (SMD), and their respective 95% CIs for continuous variables.

While proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors effectively diminish LDL-C levels, their combined use with statins for reducing major adverse cardiovascular events (MACE) and improving lipid profiles post-PCI requires further validation. This study seeks to appraise the therapeutic impact of PCSK9 inhibitors combined with statins on MACE and blood lipids in patients following PCI. METHODS: Randomized controlled trials (RCTs) and cohort studies as of February 2025 in the PubMed, Embase, Cochrane Library, and Web of Science databases were identified.

However, there remained a dearth of direct comparative studies among different PCSK9 inhibitors. Therefore, this study aimed to conduct a network meta-analysis to evaluate the efficacy and safety of different PCSK9 inhibitors combined with statins. METHODS: A comprehensive literature search was conducted from the study's inception to 12 November 2023, encompassing multiple online databases including PubMed, Embase, Cochrane Central, Web of Science, and ClinicalTrials.gov to obtain relevant randomized controlled trials. Frequentist network meta-analysis was employed to compare the efficacy and safety of different PCSK9 inhibitors. The efficacy endpoints were low-density lipoprotein cholesterol (LDL-C), apolipoprotein B (ApoB), and lipoprotein (a) (Lp(a)). The safety endpoints were any adverse events (AE), severe adverse events (SAE), AE leading to treatment discontinuation, and injection-site reaction.

This study examined the impact of PCSK9i on quality of life in ACS patients, comparing PCSK9i plus statin versus statin-only therapy using PROMIS-10, and analyzed the association between PROMIS scores and major adverse cardiovascular events (MACE). The EMSIACS trial is a prospective, randomized, open-label, parallel-group, multicenter study registered at ClinicalTrials.gov (NCT04100434). This paper presents the exploratory outcomes of this trial. From September 2020 to March 2022, a total of 500 ACS patients were enrolled. Patients were randomly assigned in a 1:1 ratio to receive Evolocumab plus statin therapy or statin-only therapy. The quality of life was assessed using PROMIS 10 at baseline, week 12, and week 48. PROMIS 10 includes two summary scores: Global Physical Health (GPH, including physical health, physical function, fatigue and pain intensity) and Global Mental Health (GMH, including overall quality of life, mental health, satisfaction with social activities, and emotional problems)."},{"id":"source_9","type":"source","study":"Efficacy of PCSK9 Inhibitors on Clinical Outcomes in Patients with Established Atherosclerotic Cardiovascular Disease: A Network Meta-analysis","year":2025,"doi":"10.1007/s40256-025-00778-1","url":"https://doi.org/10.1007/s40256-025-00778-1","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Raone 2025","quote":"Evolocumab (140 mg every 2 weeks or 420 mg monthly) and alirocumab 150 mg every 2 weeks significantly reduced MACE compared with placebo (risk ratios (RR): 0.78, 95% confidence intervals (CI): 0.66-0.93 and RR: 0.47, 95% CI 0.25-0.86, respectively).

Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i), including monoclonal antibodies and small-interfering RNA agents, offer additional risk reduction, yet comparative evidence across individual regimens remains limited. METHODS AND RESULTS: We conducted a systematic review and network meta-analysis of randomized controlled trials evaluating approved PCSK9i dosages in patients with ASCVD. The primary outcome was major adverse cardiovascular events (MACE); the secondary outcomes included myocardial infarction, stroke, coronary revascularization, cardiovascular mortality, and all-cause death.

METHODS: We searched the following databases until March 2023: PubMed, Embase, Cochrane, Web of Science, CNKI, Chongqing VIP Database and Wan Fang Database. Finally, all randomized controlled trials, retrospective studies and prospective studies were included in the analysis. RESULTS: A total of 20 studies involving 48,621 patients were included in this meta-analysis. The results demonstrated that PCSK9 inhibitors group was more beneficial for ACS patients compared to control group (receiving statins alone or placebo).

However, evidence of the optimal PCSK9 agents targeting PCSK9 for secondary prevention in patients with high-risk of cardiovascular events is lacking. Therefore, this study was conducted to evaluate the benefit and safety of different types of PCSK9 inhibitors. METHODS: Several databases including Cochrane Central, Ovid Medline, and Ovid Embase were searched from inception until March 30, 2022 without language restriction. Randomized controlled trials (RCTs) comparing administration of PCSK9 inhibitors with placebo or ezetimibe for secondary prevention of cardiovascular events in patients with statin-background therapy were identified. The primary efficacy outcome was all-cause mortality. The primary safety outcome was serious adverse events. RESULTS: Overall, nine trials totaling 54,311 patients were identified. Three types of PCSK9 inhibitors were evaluated. The use of alirocumab was associated with reductions in all-cause mortality compared with control (RR 0.83, 95% CrI 0.72-0.95)."},{"id":"source_14","type":"source","study":"Lipid-Lowering Efficacy and Safety of Oral Proprotein Convertase Subtilisin/Kexin Type 9 Inhibitors: A Systematic Review and Meta-Analysis","year":2026,"doi":"10.1007/s12325-025-03418-x","url":"https://doi.org/10.1007/s12325-025-03418-x","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Masson 2026","quote":"Compared with placebo, oral PCSK9 inhibitors significantly reduced LDL-C [mean difference (MD) - 55.7; 95% confidence interval (CI) - 59.3 to - 52.1; I 2 = 14%)] and apolipoprotein B (MD - 46.9; 95% CI - 54.6 to - 39.2; I 2 = 72.9%).

Recently, novel oral PCSK9 inhibitors have emerged, providing new evidence regarding their lipid-lowering efficacy and safety. METHODS: This systematic review and meta-analysis was conducted in accordance with PRISMA guidelines. Randomized clinical trials evaluating oral PCSK9 inhibitors and reporting percentage changes in lipid parameters and/or adverse events were included. A qualitative synthesis was performed for all studies meeting predefined eligibility criteria, followed by a quantitative synthesis of studies with sufficient data for statistical pooling. RESULTS: Seven randomized clinical trials were included in the qualitative analysis, of which four were eligible for meta-analysis. Five oral PCSK9 inhibitors were identified. Three agents (MK-0616, AZD0780, and NNC0385-0434) contributed to the quantitative analysis, while two (DC371739 and CVI-LM001) were assessed descriptively."},{"id":"source_15","type":"source","study":"PCSK9 inhibitoRs for Early Passivation of coRonary athEroSclerotic plaqueS in acute coronary syndromes (REPRESS): study protocol for a multicentre randomised controlled trial","year":2026,"doi":"10.1136/bmjopen-2025-112947","url":"https://doi.org/10.1136/bmjopen-2025-112947","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"some_concerns","directness":"direct","cited_as":"Chen 2026","quote":"The primary endpoint will be analysed using analysis of covariance, adjusting for treatment group, baseline LDL-C stratification (≥1.8 vs <1.8 mmol/L), and baseline minimum FCT. 1 Because non-culprit plaques are prone to rupture and thrombosis, patients with ACS remain at elevated risk of recurrent cardiovascular events, especially during the first 30 to 90 days after discharge.","evidence_span":"The background evidence for pcsk9 inhibitors effects is heterogeneous rather than uniformly confirmatory.

Proprotein convertase subtilisin/kexin type 9 inhibitors (PCSK9i) are increasingly used alongside statins to achieve guideline-recommended LDL-C targets after ACS. However, despite substantial LDL-C reductions with early PCSK9i initiation, their effects on non-culprit coronary atherosclerotic plaques remain unclear. This study aims to assess the impact of early intensive LDL-C lowering with PCSK9i added to moderate-intensity statin therapy on optical coherence tomography (OCT)-derived plaque characteristics in non-culprit coronary lesions in patients with ACS. METHODS AND ANALYSIS: In this prospective, multicentre, open-label trial, 212 patients with ACS will be randomised 1:1 to an early intensified lipid-lowering strategy (PCSK9i added to moderate-intensity statin) or guideline-directed medical therapy for 6 months. Serial OCT imaging of non-culprit coronary arteries with 20-70% stenosis will be performed at baseline and 6 months."},{"id":"source_16","type":"source","study":"Efficacy and safety of PCSK9 inhibitors, potent statins, and their combinations for reducing low-density lipoprotein cholesterol in hyperlipidemia patients: a systematic network meta-analysis","year":2025,"doi":"10.3389/fcvm.2024.1415668","url":"https://doi.org/10.3389/fcvm.2024.1415668","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Jiang 2025","quote":"Meanwhile, compared with placebo, evolocumab (MD -1.89, 95% CI -2.27 to -1.50), alirocumab (MD -1.83, 95% CI -2.09 to -1.57), rosuvastatin (MD -1.93, 95% CI -2.30 to -1.56), inclisiran (MD -1.68, 95% CI -2.10 to -1.27), and atorvastatin (MD -1.68, 95% CI -2.04 to -1.31) could also play a role in the treatment of LDL-C reduction.

METHODS: A systematic search was conducted across databases including PubMed, Embase, and the Cochrane Library to explore lipid-lowering therapies in hyperlipidemia from their inception to 7 November 2023. A network meta-analysis (NMA) was conducted via Stata 17 software, with two authors independently conducting the search, screening, and data abstraction. RESULTS: A total of 68 clinical studies involving 21,288 patients with hyperlipidemia were incorporated into the NMA. PSCK9 inhibitors and potent statins significantly reduced LDL-C levels from baseline vs. placebo regardless of background therapy. Regarding the efficacy of lipid reduction, four principal medications were evaluated: evolocumab and atorvastatin [mean standard deviation (MD) -3.41, 95% CI -4.81 to -2."},{"id":"source_17","type":"source","study":"PCSK9 inhibitors and inclisiran with or without statin therapy on incident muscle symptoms and creatine kinase: a systematic review and network meta-analysis","year":2024,"doi":"10.3389/fcvm.2024.1375040","url":"https://doi.org/10.3389/fcvm.2024.1375040","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Li 2024","quote":"Review Manager 5.3 software was utilized to calculate relative risks with 95% confidence intervals (CIs) for dichotomous data and mean differences or standardized mean differences with 95%CIs for continuous data.

PCSK9 inhibitors (PCSK9i) reduce LDL-C and Lp(a), however, the effect of dual lipid reduction on mechanical vascular function remains unclear. The aim of this study was to evaluate the efficacy of PCSK9i in reducing LDL-C and Lp(a) and to assess the relationship between the dual lipid reduction and the mechanical vascular profile improvement in FH subjects. METHODS: This prospective observational study included 301 genetically confirmed FH subjects treated with PCSK9i added to high-intensity statins and ezetimibe. Biochemical and PWV measurements were performed at baseline and after six months. Subjects were stratified into four groups based on median values of ΔLDL-C and ΔLp(a). RESULTS: After six months of add-on PCSK9i, 44.9% of FH subjects achieved their LDL-C targets. Reductions were observed in LDL-C (− 49.8%, p < 0.001), Lp(a) (− 21.4%, p < 0.001), and PWV (Δ − 22.7%, p < 0.001). PWV improvement increased across groups with greater lipid reductions (p for trend < 0.01); Group 3 and Group 4 exhibited a similar mechanical vascular benefit."},{"id":"source_19","type":"source","study":"PCSK9 inhibitors and osteoporosis: mendelian randomization and meta-analysis","year":2024,"doi":"10.1186/s12891-024-07674-w","url":"https://doi.org/10.1186/s12891-024-07674-w","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Chen 2024","quote":"The meta-analysis involving a total of 1,263,102 subjects, showed that PCSK9 inhibitors can increase osteoporosis risk ( P < 0.05, I 2 , 39%).

Yet, PCSK9's impact on osteoporosis remains unclear. Hence, we employed Mendelian randomization (MR) analysis for examining PCSK9 inhibitor effects on osteoporosis. METHODS: Single nucleotide polymorphisms (SNPs) for 3-hydroxy-3-methylglutaryl cofactor A reductase (HMGCR) and PCSK9 were gathered from available online databases for European pedigrees. Four osteoporosis-related genome-wide association studies (GWAS) data served as the main outcomes, and coronary artery disease (CAD) as a positive control for drug-targeted MR analyses. The results of MR analyses examined by sensitivity analyses were incorporated into a meta-analysis for examining causality between PCSK9 and HMGCR inhibitors and osteoporosis. RESULTS: The meta-analysis involving a total of 1,263,102 subjects, showed that PCSK9 inhibitors can increase osteoporosis risk (P < 0.05, I 2 , 39%).

PCSK9 inhibitors have been shown to remarkably reduce cardiovascular events in patients at high risk, but data on their impact on sudden cardiac death (SCD) and ventricular arrhythmias are limited. This study aimed to evaluate whether PCSK9 inhibitor therapy reduces the risk of SCD and ventricular arrhythmias. METHODS: PubMed and Embase were searched up to September 1, 2024 and combined with data from ClinicalTrials.gov. Randomized controlled trials of PCSK9 inhibitors with ≥ 450 patients and follow-up of ≥ 48 weeks were considered for inclusion. Primary outcomes were the incidence of SCD and ventricular arrhythmias. We used a random-effects model to synthesize the data, calculating risk ratio (RR) and 95% confidence intervals (CI). Heterogeneity between studies was assessed with I² statistics. Risk of bias was assessed using the Cochrane risk of bias tool. RESULTS: A total of 12 articles with 16 trials involving 90,764 patients were included. The follow-up duration ranged from 48 weeks to 3.4 years."},{"id":"source_21","type":"source","study":"Effectiveness of PCSK9 inhibitors: A Target Trial Emulation framework based on Real-World Electronic Health Records","year":2024,"doi":"10.1371/journal.pone.0309470","url":"https://doi.org/10.1371/journal.pone.0309470","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Barbati 2024","quote":"Inhibition of PCSK9 by the use of monoclonal antibodies has been demonstrated to significantly reduce LDL values (Low-Density Lipoprotein) by 50-70%, regardless of the therapeutic background in which it is implemented (monotherapy or in combination with the standard Lipid-Lowering Therapy, LLT) [ 6 ].

In the last years, Proprotein Convertase Subtilisin-Kexin type 9 inhibitors (PCSK9-i) has emerged as a key therapeutic target to lower LDL and were introduced for prevention of CV events. Recently (June 2022) the Italian Medicines Agency (AIFA) modified the eligibility criteria for the use of PCSK9-i. We designed an observational study to estimate the prevalence of eligible subjects and evaluate the effectiveness of PCSK9-i applying a Target Trial Emulation (TTE) approach based on Electronic Health Records (EHR). Subjects meeting the eligibility criteria were identified from July 2017 (when PCSK9-i became available) to December 2020. Outcomes were all-cause death and the first hospitalization. Among eligible subjects, we identified those treated at date of the first prescription.

METHODS: This has a multicenter, quasi-experimental design carried out in 12 Spanish hospitals from May 2020 to February 2023. Cognitive function was assessed using the Montreal Cognitive Assessment (MoCA). RESULTS: Among 158 patients followed for a median of 99 weeks, 52% were taking evolocumab and 48% alirocumab; the mean change from baseline in MoCA score at follow-up was + 0.28 [95% CI (- 0.17 to 0.73; p = 0.216)].

All patients who remained with an LDL > 3.5 with very high cardiovascular risk or LDL > 4.0mmol/L with high risk were initiated on alirocumab injection every 2 weeks. Monitoring including biochemical analysis including immunotherapy levels, troponin, brain natriuretic peptides, electrocardiograph and echocardiogram. PCKS9i therapy was tolerated in 9/11 patients with 2 stopping treatment, one due to nausea & vomiting and one due to elevation in creatinine kinase. No adverse effects related to the heart transplant were detected and no significant change in creatinine kinase, liver function or left ventricular ejection fraction were seen. A significant reduction in LDL, total cholesterol, triglycerides was seen with LDL cholesterol reduction of 55% from 4.14 ± 0."},{"id":"source_25","type":"source","study":"Comparative Efficacy of Statins Versus PCSK9 Inhibitors in Coronary Heart Disease Treatment","year":2026,"doi":"10.1161/JAHA.125.047923","url":"https://doi.org/10.1161/JAHA.125.047923","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Yu 2026","quote":"After 1 month, low‐density lipoprotein cholesterol reduction was greater in the PCSK9 inhibitor group (from 2.57 to 0.75 mmol/L) than in the statin group (from 2.29 to 1.40 mmol/L; P <0.001).

However, it remains unclear which monotherapy offers greater cardiovascular benefit. METHODS: This prospective non-randomized real-world observational cohort study enrolled coronary heart disease inpatients from July 2020 to March 2024. Patients received either alirocumab (75 mg/2 weeks) or statins (atorvastatin 20 mg/day or rosuvastatin 10 mg/day). The primary outcome was a composite of cardiovascular death, myocardial infarction, stroke, heart failure hospitalization, or coronary revascularization. Cox proportional hazards models and restricted mean survival time analyses were used. RESULTS: Among 1165 analyzed patients, 215 received PCSK9 inhibitors and 950 received statins. After 1 month, low-density lipoprotein cholesterol reduction was greater in the PCSK9 inhibitor group (from 2.57 to 0.75 mmol/L) than in the statin group (from 2.29 to 1.40 mmol/L; P <0.001).

AIS frequently coexists with coronary heart disease (CHD), complicating treatment and leading to more severe symptoms and worse outcomes. Shared risk factors between CHD and AIS, especially elevated low-density lipoprotein cholesterol (LDL-C), contribute to atherosclerosis and inflammation, which worsen brain tissue damage. Proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitors offer a promising treatment option. They effectively lower LDL-C levels and may help reduce END in AIS patients with CHD. This study aims to evaluate how effective PCSK9 inhibitors are in reducing END among this high-risk group and to provide new insights for treatment strategies.

It is commonly acknowledged that low-density lipoprotein (LDL) is a major cause of ASCVD. Several online databases and search engines, such as Pub- Med and the Cochrane Library, were used to conduct a thorough search. METHODS: This study included RCTs assessing the effect of PCSK9 inhibitors on cardiovascular events. The RevMan 5.4 software was used to conduct the meta-analysis. This analysis included nine RCTs in total. RESULTS: Meta-analysis of the included studies showed that the levels of total cholesterol, LDL, and triglycerides were reduced after the use of PCSK9 inhibitors, and HDL levels were increased, which is good cholesterol. Most adverse cardiac events (MACE) were reduced after the use of PCSK9 inhibitors. CONCLUSION: In conclusion, ezetimibe, a PCSK9 inhibitor added to statin therapy, further reduces MACE risk without affecting all-cause mortality, even though statins already significantly reduce major adverse cardiovascular events (MACE) and mortality."},{"id":"source_28","type":"source","study":"Safety and Effectiveness of PCSK9 Inhibitors and Inclisiran in Patients With Neuromuscular Disorders and Statin Intolerance","year":2025,"doi":"10.1111/ene.70175","url":"https://doi.org/10.1111/ene.70175","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"indirect","cited_as":"Theodorou 2025","quote":"PCSK9 inhibitors and inclisiran have been studied in patients with homozygous or heterozygous familial hypercholesterolemia, atherosclerotic cardiovascular disease (ASCVD), and ASCVD risk equivalent (a high‐risk primary prevention cohort comprising individuals with type 2 diabetes mellitus, familial hypercholesterolemia, or a 10‐year risk of a CV event ≥ 20% [by Framingham Risk Score or equivalent]).

We assessed the safety and efficacy of PCSK9 inhibitors and inclisiran in this specific patient subgroup. METHODS: We conducted an observational cohort study evaluating patients with available clinical and laboratory data prior to and at prespecified time points following treatment initiation with PCSK9 inhibitors or inclisiran. RESULTS: Eleven patients with neuromuscular disorders and statin intolerance were included in this study. Median follow-up time after PCSK9 inhibitor or inclisiran initiation was 14 (9-17) months. PCSK9 inhibitors or inclisiran use led to a significant decrease in mean low-density lipoprotein cholesterol levels. Moreover, all patients tolerated these lipid-lowering agents without exacerbation of their underlying myositis, myopathy, neuromuscular junction disorder, and without presenting any adverse event or relapse of myotoxicity and/or hepatotoxicity."},{"id":"source_29","type":"source","study":"Beyond maximally tolerated statins: PCSK9 inhibitors as a critical adjunct for cardiovascular risk reduction in peripheral artery disease-a systematic review and meta-analysis.","year":2026,"doi":"10.1080/03007995.2026.2662127","url":"https://doi.org/10.1080/03007995.2026.2662127","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Ariyanti 2026","quote":"PCSK9 inhibitors significantly reduced MACE (HR 0.77; 95% CI: 0.65 to 0.92) and lowered LDL-C levels (MD -55.76 mg/dL; 95% CI: -63.19 to -48.34).

This meta-analysis aimed to evaluate their effects on cardiovascular, functional, limb, and survival outcomes in PAD. METHODS: We systematically searched PubMed, Scopus, and ClinicalTrials.gov through August 2025 for RCTs and cohort studies comparing PCSK9 inhibitors with placebo or standard therapy in PAD. Primary outcomes were MACE and major amputation. Data were analyzed using fixed- or random-effects models depending on heterogeneity. RESULTS: Six studies (five RCTs, one cohort) involving 4,563 patients were included. PCSK9 inhibitors significantly reduced MACE (HR 0.77; 95% CI: 0.65 to 0.92) and lowered LDL-C levels (MD -55.76 mg/dL; 95% CI: -63.19 to -48.34). Positive but non-significant trends were observed for major amputation (HR 0.35; 95% CI: 0.11 to 1.07), all-cause mortality (HR 0.58; 95% CI: 0.26 to 1.30), and walking performance (SMD 2.38; 95% CI: -1.97 to 6.73)."},{"id":"source_30","type":"source","study":"Effect of PCSK9 inhibitors on major cardiac adverse events and lipoprotein-a in patients with coronary heart disease: a meta-analysis.","year":2025,"doi":"10.1097/mca.0000000000001464","url":"https://doi.org/10.1097/mca.0000000000001464","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Hu 2025","quote":"The results showed that compared with the control group, PCSK9 inhibitors significantly reduced low-density lipoprotein cholesterol (WMD = -1.24 mmol/L, 95% confidence interval (CI): -1.28 to -1.20), total cholesterol, triglycerides, and Lp(a) levels while increasing high-density lipoprotein cholesterol levels.

METHODS: Randomized controlled trials (RCTs) were systematically searched in PubMed, the Cochrane Library, and other databases. Stata 15.1 software was used for data analysis, and a random- or fixed-effects model was selected based on inter-study heterogeneity. Egger's test was applied to detect publication bias.

Monoclonal antibodies that inhibit proprotein convertase subtilisin-kexin type 9 (PCSK9) reduce low-density lipoprotein (LDL) cholesterol levels and subsequently the risk of cardiovascular events in patients with dyslipidaemia. There are no published data on the effect of this medication class on cholesterol levels in patients after cardiac transplantation. METHODS: In this retrospective study we investigated patients who were treated with PCSK9 inhibitors either because of intolerance of statins or residual hypercholesterolaemia with evidence of cardiac allograft vasculopathy. We compared the data of patients prior to the start with these medications with their most recent dataset. RESULTS: Ten patients (nine men; mean age 58±6 years) underwent cardiac transplantation 8.3±4.5 (range 3-15) years ago. The treatment duration of Evolocumab or Alirocumab was on average 296±125 days and lead to a reduction of total Cholesterol (281±52 mg/dl to 197±36 mg/dl; p = 0.002) and LDL Cholesterol (170±22 mg/dl to 101±39 mg/dl; p = 0.001)."},{"id":"source_33","type":"source","study":"Proprotein convertase subtilisin/kexin 9 inhibitors in reducing cardiovascular outcomes: a systematic review and meta-analysis.","year":2019,"doi":"10.1136/heartjnl-2019-314763","url":"https://doi.org/10.1136/heartjnl-2019-314763","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Du 2019","quote":"Dichotomous variables from individual studies were pooled by relative risks (RR) and their 95% CIs using the random-effect model.

Design Bayesian network meta-analysis was conducted to compare treatment groups. Methods Thirty-nine randomized controlled trials were selected using MEDLINE, EMBASE, and CENTRAL (inception - September 2017). Results In network meta-analysis of 189,116 patients, PCSK9 inhibitors were ranked as the best treatment for prevention of major adverse cardiovascular events (Surface Under Cumulative Ranking Curve (SUCRA), 85%), myocardial infarction (SUCRA, 84%) and stroke (SUCRA, 80%). PCSK9 inhibitors reduced the risk of major adverse cardiovascular events compared with ezetimibe + statin (odds ratio (OR): 0.72; 95% credible interval (CrI), 0.55-0.95; Grading of Recommendation Assessment, Development and Evaluation (GRADE) criteria: moderate), statin (OR: 0.78; 95% CrI: 0.62-0.97; GRADE: moderate) and placebo (OR: 0.63; 95% CrI: 0.49-0.79; GRADE: high). The PCSK9 inhibitors were consistently superior to groups for major adverse cardiovascular event reduction in secondary prevention trials (SUCRA, 95%)."},{"id":"source_35","type":"source","study":"Cardiovascular Efficacy and Safety of PCSK9 Inhibitors: Systematic Review and Meta-analysis Including the ODYSSEY OUTCOMES Trial.","year":2018,"doi":"10.1016/j.cjca.2018.04.002","url":"https://doi.org/10.1016/j.cjca.2018.04.002","population":"not extracted","intervention_or_exposure":"not extracted","comparator":"not extracted","endpoint":"not extracted","effect":"not extracted","risk_of_bias":"not appraised in public sidecar","directness":"review","cited_as":"Turgeon 2018","quote":"We systematically reviewed and meta-analyzed randomized controlled trials with durations ≥ 6 months comparing MACE, mortality, and safety with PCSK9 inhibitors vs control.

Therefore, additional LDL-C reduction may be warranted, especially for patients who are unresponsive to, or unable to take, existing LDL-C-reducing therapies. By inhibiting the proprotein convertase subtilisin/kexin type 9 (PCSK9) enzyme, monoclonal antibodies (PCSK9 inhibitors) may further reduce LDL-C, potentially reducing CVD risk as well. OBJECTIVES: Primary To quantify short-term (24 weeks), medium-term (one year), and long-term (five years) effects of PCSK9 inhibitors on lipid parameters and on the incidence of CVD. Secondary To quantify the safety of PCSK9 inhibitors, with specific focus on the incidence of type 2 diabetes, cognitive function, and cancer. Additionally, to determine if specific patient subgroups were more or less likely to benefit from the use of PCSK9 inhibitors. SEARCH METHODS: We identified studies by systematically searching the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, Embase, and Web of Science."}],"edges":[{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_1","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_2","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_3","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_4","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_5","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_6","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_7","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_8","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_9","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_10","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_11","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_12","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_13","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_14","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_15","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_16","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_17","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_18","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_19","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_20","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_21","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_22","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_23","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_24","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_25","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_26","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_27","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_28","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_29","type":"contains_claim"},{"from":"bb8686c3-28f9-4609-95f1-70d7581bf992","to":"claim_30","type":"contains_claim"}],"screening":{"identified":36,"screened":36,"excluded":0,"included":36,"included_or_retained":36,"flow":["identified","screened","excluded_with_reasons","included"],"wording":"36 candidate receipts retained after source retrieval, deduplication, and topic filtering.
