However, the association of these strategies with long-term outcomes and the identification of patient subgroups that might benefit from tailored approaches remain unclear.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objective: &lt;/strong&gt;To compare immediate vs delayed or selective coronary angiography treatment strategies for patients with OHCA without ST elevation and the effect on 1-year survival, and identify subgroups that may differ in treatment effect based on patient or clinical features.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Data sources: &lt;/strong&gt;Ovid MEDLINE, Embase, and Clarivate/Web of Science Core Collection were searched for relevant literature from inception to September 8, 2022.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Study selection: &lt;/strong&gt;RCTs investigating immediate vs delayed or selective coronary angiography after OHCA without ST-segment elevations and a minimum follow-up period of 1 year.

With growing knowledge of the genetic basis for PAD and related risk factors, there is potential opportunity to identify individuals at high risk using polygenic risk scores (PRSs).ObjectiveTo develop a novel integrated, multiancestry polygenic score for PAD (PRS-PAD) and evaluate its risk estimation for PAD and major adverse limb events in 3 populations.Design, Setting, and ParticipantsThis longitudinal cohort study was conducted among individuals with genotyping and electronic health record data in the UK Biobank (2006-2021), All of Us (AoU, 2018-2022), and the Mass General Brigham Biobank (MGBB, 2010-2023). Data were analyzed from July 2023 to February 2025.ExposuresPRS-PAD, previously published PAD polygenic scores, and clinical risk factors.Main Outcomes and MeasuresThe primary outcomes were PAD and major adverse limb events, defined as a surrogate of major amputation and acute limb ischemia.ResultsThe study populations included 400 533 individuals from the UK Biobank (median [IQR] age, 58.2 [45.0-71.4] years; 216 215 female participants [53.9%]), 218 500 from AoU (median [IQR] age, 53.6 [37.7-65.0] years; 132 647 female participants [60.7%]), and 32 982 from MGBB (median [IQR] age, 56.0 [32.0-80.0] years; 18 277 female participants [55.4%]). In the UK Biobank validation cohort, PRS-PAD was associated with an odds ratio [OR] per SD increase of 1.63 (95% CI, 1.60-1.68; P < .001). After adjusting for clinical risk factors, the OR for the top 20% of PRS-PAD was 1.68 (95% CI, 1.62-1.74; P < .001) compared to the remainder of the population. Among PAD cases without a history of diabetes, smoking, or chronic kidney disease (n = 3645), 1097 individuals (30.1%) had a high PRS-PAD (top 20%). In incident disease analysis, PRS-PAD improved discrimination (C statistic, 0.761), which was nearly equivalent to the performances of diabetes (C statistic, 0.760) and smoking (C statistic, 0.765). Among individuals with prevalent PAD, high PRS-PAD was associated with an increased risk of incident major adverse limb events in the UK Biobank (hazard ratio [HR], 1.75; 95% CI, 1.18-2.57; P = .005), MGBB (HR, 1.56; 95% CI, 1.06-2.30; P = .02), and AoU (HR, 1.57; 95% CI, 1.06-2.33; P = .03).Conclusions and RelevanceThis cohort study develops a new PRS that stratifies risk of PAD and adverse limb outcomes. Incorporating polygenic risk into PAD care warrants further investigation to guide screening and tailor management to prevent major adverse limb events.","PeriodicalId":14657,"journal":{"name":"JAMA cardiology","volume":"135 1","pages":""},"PeriodicalIF":24.0,"publicationDate":"2025-05-21","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144103739","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
