Background: This study aims to investigate the value of the CHA2DS2-VASc score in predicting long-term major cardiovascular events following coronary artery bypass grafting. 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 CHA 2 DS 2 -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 CHA 2 DS 2 -VASc score (p
