AbstractThe aim of this study was to evaluate short- and long-term outcome in patients undergoing coronary artery bypass grafting (CABG), who received an intra-aortic balloon pump (IABP) prior to surgery. Between January 1990 and June 2004, all patients (n=154) who received an IABP prior to on-pump CABG in our center were included. Patients received the IABP for vital indications (i.e. either unstable angina refractory to medical therapy or cardiogenic shock; group 1: n=99) or for prophylactic reasons (group 2: n=55). A Cox proportional hazards model was used to identify predictors of long-term all-cause mortality. Compared with the EuroSCORE predictive model, observed 30-day mortality in group 1 (15.2%) was slightly higher than predicted (10.3%). A decrease in 30-day mortality occurred in group 2 (median predicted mortality was 7.2% and observed was 0%). Cumulative 1-, 5-, and 6-year survival was 82.8+/-3.8%, 70.1+/-4.9%, and 67.3+/-5.1% for group 1 vs. 98.2+/-1.8%, 84.0+/-5.6% and 84.0+/-5.6% for group 2 (Log-rank: P=0.02). Logistic EuroSCORE (HR 1.03 [1.01-1.05], P=0.007) was an independent predictor of long-term all-cause mortality.
