Introduction: European System for Cardiac Operative Risk Evaluation (EuroSCORE) has been used to predict the postoperative mortality rate for patients undergoing open-heart surgery. The contributions of EuroSCORE in off-pump coronary artery bypass grafting (CABG) has not yet clearly elucidated. Methods: Consecutive patients of isolated off-pump CABG performed from 2000 when we start performing 'routine' off-pump procedures were stratified using the additive EuroSCORE. Incidence of postoperative mortality, morbidity, and recovery were assessed, and compared to an historical cohort of on-pump procedures performed between 1991 until 1998 when CABG had been routinely performed under on-pump. Results: There were 1318 patients in the off-pump and 1162 patients in the on-pump group. EuroSCORE of the off-pump group was significantly higher than that of the on-pump group. In both the on-and off-pump groups, mortality, total incidence of major complications, heart failure, and renal failure, and three parameters of recovery time were well correlated with EuroSCORE; however, the discriminatory power of the EuroSCORE model was always better in the on-pump group than in the off-pump group. Stroke was correlated with EuroSCORE only in the on-pump group. Pneumonia, mediastinitis postoperative myocardial infarction, or mediastinitis was not correlated with EuroSCORE in either group. In the off-pump group, postoperative major complication was reduced and postoperative recovery was shortened significantly, compared to those in the on-pump group. Conclusion: In off-pump CABG, EuroSCORE can, but not as good as in on-pump CABG, predict mortality, certain major postoperative complications, and postoperative recovery. This suggests off-pump technique appears to modify the risk stratification of the patients undergoing CABG. (C) 2010 Published by European Association for Cardio-Thoracic Surgery.
