Abstract

From August 1992 to July 1996, 63 consecutive patients underwent coronary artery bypass surgery. The mean age of these patient was 57 years(range form 30 to 71years). There were 44 men and 19 women. Preoperative 12 patients had stable angina pectoris and 23 patients were unstable angina pectoris. 8 patients had previous myocardial infarctation history and emergency or urgent myocardial revascularization were performed in 9 cases. In the risk factors of coronary atherosclerosis, 25 patients(40%) were hypercholesterolemia, 38 patients(60%) have smoking history and 19 patients(30%) have hypertension history. In the patterns of disease, 9 patients were single vessel disease, 18 patients were two vessele disease and 33 patients were three vessel dise 3se. We performed total 284 distal anastomosis(mean 3.5 anastomosis per patient) and performed one case of ascending aorta graft interposition, two cases of mitral valve replacement, one case of aortic valve replacement, one case of ventricular septal defect repair and one case of atrial septal defect repair and the mean aortic cross clamp time was 115.3 minutes. The common complications were arrhythmia(7cases), wound infection(5cases), perioperative myocardial infarction(4cases), reoperation for bleeding control(4cases) and stroke(4cases). There were six hospital deaths due to low cardiac output syndrome, ventricular arrhythmia and respiratory failure. In the evaluation of operative risk factors, preoperative intravenous nitroglycerin requirement and prolonged aortic cross clamp time(>2hours) were found to be predective factor of morbidity and old age(>65years) was
