Objective To analyze the early clinical outcome of high-operative-risk coronary artery bypass grafting （CABG） classified according European System for Cardiac Operative Risk Evaluation （EuroSCORE）. Methods Classified eighty-four patients accepted CABG from Feb. 2004 to Sep. 2004 in our ward to high-operativerisk group （≥6, n=40） and low-medium-operative-risk group （0-5, n=44） according EuroSCORE. Record the operative schemes, complications after operation and evaluate the severe state with acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ ） and sequential organ failure assessment（SOFA） for all patients. Compare the early clinical outcome between the two groups. Results The operative mortality, ratio of long ICU-staying time, incidence of complications and severe degree of high-operative-risk group were higher than those in the low-mediumoperative-risk group. Standard EuroSCORE had significant positive correlation with either of A0, A1, Amax or S1, Smax counted in total patients （P〈0. 01）, and the same as logistic EuroSCORE （P〈 0. 05）. But when compared the relationships in certain risk ranks, only in high-operative-risk group the positive correlation was found between standard EuroSCORE and A1, Amax, S1 and Smax （P〈 0. 05）, between logistic EuroSCORE and Amax （P〈 0. 05）. Conclusion EuroSCORE could evaluate overall operative risk perfectly in our patients, and maybe more sensitively in the high-operative-risk patients. Many factors could improve the prognosis of high-operative-risk patients： accurate evaluation of the operative risk before surgery; perfect myocardial protection, effective myocardial revascularization and thorough correction of malformation in operation, and proper postoperative management in time.
