Incidence and Predisposing Factors of Atrial Fibrillation After Coronary Artery Bypass Surgery

Aim: In patients undergoing coronary artery bypass grafting (CABG), development of new-onset postoperative atrial fibrillation (POAF) is related with more postoperative complications. In this study we aim to detect and try to control the most common predictors of POAF among our patients who underwent solely CABG operation. Material and Method: We retrospectively examined retrospectively the data of all the patients (n=149) who had undergone CABG operation at our institution between 2008 and 2012. While evaluating the possible predisposing factors, we specifically investigated age, body mass index, diabetes mellitus, preoperative creatinine value, the number of postoperative erythrocyte suspension replacement, preoperative ejection fraction levels and the number of distal bypasses. Results: POAF occurred in 55 of 149 patients (36.9%). There was a significant correlation between advanced age and occurrence of POAF (
