Abstract:
BACKGROUND: Postoperative atrial fibrillation is the most frequently arrhythmic complication associated with coronary artery bypass graft surgery. This study was designed to investigate the incidence of atrial fibrillation in patients undergoing OPCAB and on-pump CABG and to identify the risk factors associated with its development. MATERIAL AND METHOD: 247 consecutive patients were evaluated among 306 patients who underwent the coronary artery bypass graft surgery between January, 2002 and December, 2005. 178 patients underwent OPCAB (OPCAB group) and 69 patients underwent On-pump CABG (On-pump CABG group). The incidence and the risk factors of atrial fibrillation in two groups were determined. RESULT: There were no significant differences between two groups with respect to the preoperative demographic characteristics of the patients. The incidences of postoperative atrial fibrillation were 25 cases (14%) in OPCAB group and 15 cases (21%) in On-pump CABG group. Age over 65 years, net positive fluid imbalance for postoperative 3 days, and chest tube bleeding for postoperative 3 days were independent predictive factors in OPCAB group. Age over 65 years and net positive fluid imbalance for postoperative 3 days were independent predictive factors in On-pump CABG group. In multivariate analysis, age over 65 years was the only risk factor of postoperative atrial fibrillation in both groups. CONCLUSION: Atrial fibrillation is a common complication after procedures of myocardial revascularization. There wasn't a low incidence of postoperative atrial fibrillation in OPCAB, compared with On-pump CABG. Age over 65 years was associated with postoperative atrial fibrillation irrespective of the use of cardiopulmonary bypass.
