    Objective To learn the predictive risk factors of acute conversion of off-pump coronary artery bypass grafting (off-pump CABG)to on-pump coronary artery bypass grafting (on-pump CABG), referring for making decision in operating. Methods During Jan. 2002 to May 2006, 546 patients underwent planned off-pump CABG were analyzed retrospectively, and cases of acute conversion of off-pump to on-pump CABG (converted group) were compared with unconverted to on-pump(off-pump group) by multivariate logistic regression. Results 24 patients of off-pump CABG were acutely converted to on-pump CABG because of ventricular fibrillation or unstable hemodynamics. The mortality in converted group was 16.7%(4/24), much higher than off-pump group [27% (14/522) , P<0.001]. By multivariable logistic regression, acute myocardial infarction (OR=3.142,P=0004), emergent CABG (OR=1.571,P=0.011) and right main coronary artery(RCA) stenosis less than 90% (OR=1922,P=0.024) were predictors of acute conversion of off-pump to on-pump. Conclusions The mortality in patients undergoing acute conversion of off-pump to on-pump coronary artery surgery is high. When applying off-pump CABG in patients with acute myocardial infarction, emergency CABG and right main RCA stenosis ≤90%, preventive set up of extracorporeal circulation is necessary.
