All-cause mortality was markedly reduced (9.33% vs. 20.68% HR: 0.388, 95% CI: 0.373-0.404, p < 0.0001).</p><p><strong>Conclusion: </strong>This large-scale study demonstrates that in PAF patients CA is associated with lower ischemic stroke rates and all-cause mortality compared to a PSM group without CA. These findings support urgent evaluation of CA in managing PAF and highlight its role in potentially improving survival and reducing stroke risk. Further trials are needed to support these findings.</p>","PeriodicalId":11869,"journal":{"name":"European Heart Journal - Quality of Care and Clinical Outcomes","volume":" ","pages":""},"PeriodicalIF":4.8,"publicationDate":"2025-04-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143996836","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
