Effect of evolocumab on saphenous vein graft patency after coronary artery bypass surgery (NEWTON-CABG CardioLink-5): an international, randomised, double-blind, placebo-controlled trial.

Background: Saphenous vein graft (SVG) failure remains a substantial challenge after coronary artery bypass graft (CABG). LDL cholesterol (LDL-C) is a causal risk factor for atherosclerosis, but its role in SVG failure is not well established. We evaluated whether early initiation of intensive LDL-C lowering with evolocumab could reduce SVG failure.

Pathogenic Cardiomyopathy-Associated Gene Variants and Prognosis in Atrial Fibrillation: Results in 18,000 Clinical Trial Participants.

Background: Genetic variants in cardiomyopathy genes are associated with risk of atrial fibrillation (AF), although data on clinical outcomes for AF patients with such variants remain sparse.

Objectives: We aimed to study the prognostic implication of rare cardiomyopathy-associated pathogenic variants (CMP-PLP) in AF patients from large, well-phenotyped clinical trials.

Methods: CMP-PLP carriers were identified using exome sequencing in 5 multinational trials from the Thrombolysis in Myocardial Infarction study group (ENGAGE AF, FOURIER, SAVOR, PEGASUS, and DECLARE), with replication in the EAST-AFNET-4 trial.

Clopidogrel versus aspirin for secondary prevention of coronary artery disease: a systematic review and individual patient data meta-analysis.

Background: Aspirin monotherapy is recommended indefinitely for patients with established coronary artery disease (CAD). The aim of this individual patient level meta-analysis was to provide a comprehensive evaluation of the comparative efficacy and safety of clopidogrel versus aspirin monotherapy in patients with established CAD, most of whom had undergone percutaneous coronary intervention or had acute coronary syndrome.

Methods: We conducted a systematic search in PubMed, Scopus, Web of Science, and Embase to identify randomised trials published from database inception to April 12, 2025, comparing clopidogrel monotherapy with aspirin monotherapy in patients with established CAD who had discontinued or never started dual antiplatelet therapy.

Representation of Older Adults and Women in Randomized Trials of Noninvasive Imaging for Chest Pain.

Background: Noninvasive imaging is widely used both for initial diagnosis and to guide management of ischemic heart disease. Older adults and women with ischemic heart disease may have different responses to imaging as well as to treatments and outcomes that follow compared with younger adults and men. We aimed to study the representation of older adults and women in randomized controlled trials of noninvasive imaging among patients with acute and stable chest pain.
