ABSTRACT
Atrial fibrillation [AF] is a frequent complication after coronary artery bypass grafting [CABG] which increase morbidity and hospitalization length. To identify the predictors of atrial fibrillation and its repercussion on hospital and mid-term outcomes in patients undergoing [CABG]. We undertook a retrospective review of the data of 224 patients undergoing CABG. The mean age of the patients was 60.8 years. Atrial fibrillation was diagnosed from serial postoperative electrocardiogram. Twenty two patients developed postoperative atrial fibrillation. Multivariate analysis showed that only: age, left circumflex stenosis, sternal wound infection and low cardiac output were predictors of AF following CABG. Hospital mortality was similar in the two groups [5% Vs 9.6% P=0.7]. In our study, the incidence of post-CABG atrial fibrillation was 9.8%. Multivariate predictors were age, left circumflex lesion, sternal wound infection and low cardiac output. Hospital mortality and mid-term outcome were similar in the two groups
