Background: Atrial fibrillation (AF) is a frequent complication after coronary artery bypass grafting (CABG) which increase morbidity and hospitalization length.
Aim: To identify the predictors of atrial fibrillation and its repercussion on hospital and mid-term outcomes in patients undergoing (CABG).
Methods: 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.
Results: 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).
Conclusion: 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.
