Abstract:
Objective To review the experience of treatment of atrial fibrillation (AF) after coronary artery bypass grafting (CABG), and to analyze its risk factors. Methods 110 patients were subjected to CABG. AF occurred in 26 of them after surgery. All these patients were treated with drugs or direct current. AF group and non-AF group were studied retrospectively, with an analysis of risk factors of AF. Results The incidence of AF after CABG was 23.6%. 19 patients were treated with Amiodarone, and 17 of them had sinus rhythm restored to normal (84.2%). In 3 of 4 patients, who were treated with Esmolol, sinus rhythm restored to normal (75%). All 3 patients who were treated with direct current had their sinus rhythm restored. The occurrence of AF was related to age, volume of left atrium, pathological change in proximal-median segment of right coronary artery, and the administration of ?-receptor blockade before surgery. It was indicated by logistic regression multiple factors analysis that both advanced age and abstinence of administration of ?-receptor blockade before surgery were individual risk factors for AF. Conclusion Ventricular rhythm should be controlled positively when AF occurred after CABG. Amiodarone, Esmolol and direct current were safe and effective treatment modalities. Patients with advanced age, large left atrium and pathological change in proximal-median segment of right coronary artery, should be treated with ?-receptor blockade to prevent AF.
