METHODS: 322 consecutive patients who had undergone isolated CABG were reviewed. Preoperative, intraoperative and postoperative data were collected. Patients were grouped according to whether AF appeared postoperatively. RESULTS: AF occurred in 75 patients (23.3%). Most cases of AF (85.6%) appeared on or before the third postoperative day. The mean age for patients with AF was 62.5 years compared with 56.7 years for patients without AF (P or = 65 years (OR 2.7; 95% CI 1.5 to 5.1), lesions in the right coronary artery (OR 2.5; 95% CI 1.4 to 4.5), and early postoperative withdrawal of beta blocker (OR 3.9; 95% CI 2.1 to 7.7). CONCLUSIONS: AF remains the most common complication after CABG. Age and lesions in the right coronary artery can influence the incidence of AF, and beta blocker and magnesium may be the most economical and effective prevention for AF early after CABG.展开更多
