Abstract：Objective To analyze the risk factors of intraoperative ventricular fibrillation in male patients undergoing off-pump coronary artery bypass grafting (OPCABG).Methods The perioperative data of 1516 male patients undergoing OPCABG were investigated based on the perioperative OPCABG database from Nov.2007 to Feb.2009.The risk factors were identified by multiple logistic regression.Results 24 patients (1.6％) were suffered from intraoperative ventricular fibrillation and no patient died during OPCABG.Multivariate analysis demonstrated that preoperative ejection fraction (LVEF) less than 40％ (P ＜ 0.01,OR =17.182),more than 3 grafts (P ＜ 0.05,OR =3.233) and intraoperative atrial fibrillation (P ＜ 0.01,OR =24.979) were the independent risk factors of intraoperative ventricular fibrillation in male patients undergoing off-pump coronary artery bypass grafting.Conclusion This study shows LVEF less than 40％,more than 3 grafts and intraoperative atrial fibrillation are predominant factors of intraoperative ventricular fibrillation during OPCABG.
