Methods: Between January 2008 and January 2010, a total of 559 patients (445 males, 114 females; mean age: 62.7 +/- 9.1 years; range, 35 to 84 years) who underwent elective coronary artery bypass grafting were retrospectively analyzed. At a mean of 10.7 +/- 3.1-year follow-up, major cardiovascular events were considered as the primary endpoint.Results: The multivariate Cox hazard analysis identified the CHA2DS2-VASc score as an independent predictor of major cardiovascular events (hazard ratio: 1.615; 95% confidence interval: 1.038-2.511; p=0.034). The receiver operating characteristic curve analyses revealed that 3.5 was the most optimal cut-off value of the score predicting major cardiovascular events and the patients were divided into two groups accordingly. The Kaplan-Meier analysis demonstrated a significantly higher incidence of major cardiovascular events in proportion to a higher CHA2DS2-VASc score (p<0.001).Conclusion: CHA2DS2-VASc score >= 4, which includes many risk factors for cardiovascular events, can be used as an independent predictor of long-term major cardiovascular events after coronary artery bypass grafting.eninfo:eu-repo/semantics/closedAccessCha2ds2-Vasc ScoreCoronary Artery Bypass GraftingCoronary Artery DiseaseMajor Cardiovascular EventArticle31447948838076003WOS:001094176100006N/A10.5606/tgkdc.dergisi.2023.24964
