OBJECTIVES: To investigate the impact of postoperative AF on late mortality and cause of death in CABG patients.DESIGN: All CABG patients without preoperative AF surgically treated between January 1, 1997 and June 30, 2000 were included (N = 1419). Altogether, 419 patients (29.5%) developed postoperative AF. After a median follow-up of 8.0 years, survival data were obtained, causes of death were compared and Cox proportional hazard analysis was used to determine predictors of late mortality.RESULTS: The total mortality was 140 deaths/419 patients (33.4%) in postoperative AF patients and 191 deaths/1 000 patients (19.1%) in patients without AF. Death due to cerebral ischemia (2.6% vs. 0.5%), myocardial infarction (7.4% vs. 3.0%), sudden death (2.6% vs. 0.9%), and heart failure (6.7% vs. 2.7%) was more common among postoperative AF patients. Postoperative AF was an age-independent risk indicator for late mortality with a hazard ratio (HR) of 1.56 (95% confidence interval 1.23-1.98).CONCLUSIONS: Postoperative AF is an age-independent risk factor for late mortality in CABG patients, explained by an increased risk of cardiovascular death.
