How this score is calculated

It is built from checkable properties of the record itself: whether the article has a DOI, how many independent sources confirmed its data, whether the required fields are filled in, and how recent the latest confirmation is. Disagreement between sources and a missing identifier lower it. A value of 80 or above means the record was published without further checking; 60 to 79 means it is published at reduced confidence, with a manual check advisable. A record verified by an editor by hand is never pushed below 90 by a recalculation. This scores our data about the article, not the article itself.

Abstract

BACKGROUND: High residual platelet reactivity (HRPR) and persistent dyslipidemia remain important unmet needs in cardiovascular risk management, particularly in patients undergoing coronary revascularization. Despite intensive lipid-lowering and antiplatelet therapy, a substantial proportion of patients fail to reach recommended low-density lipoprotein cholesterol (LDL-C) targets or exhibit inadequate platelet inhibition. Inclisiran, a PCSK9-targeting small interfering RNA, represents an emerging approach for long-term LDL-C reduction. METHODS: A narrative review of the literature published between 2009 and 2025 was performed using PubMed, Scopus, Web of Science, and MEDLINE. Studies evaluating the addition of inclisiran to standard lipid-lowering therapy in patients with dyslipidemia and HRPR, assessed using the VerifyNow assay, were included. Illustrative clinical cases from Kazakhstan were analyzed to demonstrate real-world changes in LDL-C levels and platelet reactivity following insufficient response to conventional treatment. The review had a descriptive design. RESULTS: Available evidence indicates that a significant proportion of high- and very-high-risk patients do not achieve LDL-C targets or are unable to tolerate high-intensity statin therapy. Inclisiran consistently induces sustained reductions in LDL-C and circulating PCSK9 levels. Emerging data suggest a potential indirect modulation of platelet reactivity associated with intensive lipid lowering. In patients at extreme cardiovascular risk-including those after coronary artery bypass grafting (CABG) and with long-standing multivessel coronary artery disease-inclisiran therapy was associated with marked LDL-C reduction and a trend toward normalization of platelet reactivity. CONCLUSIONS: Assessment of platelet function using the VerifyNow assay may improve identification of residual thrombotic risk in patients with advanced atherosclerotic disease. Inclisiran appears to be a promising adjunctive therapy for dyslipidemic patients with persistently elevated cardiovascular risk and HRPR despite standard treatment. Further prospective studies are warranted to clarify the relationship between intensive LDL-C lowering, platelet reactivity, and clinical outcomes, and to optimize integrated lipid-lowering and antiplatelet strategies.
