We have assessed the long-term prognosis about cardiac death of isolated coronary artery bypass surgery from 1972 to 1988 in 361 consecutive patients. The duration of follow-up were from 0.4 years to 14.6 (mean 5.7) years. Of the 361 study patients, the operative morality was 4.7% (17 patients) and 29 patients (8.0%) died during follow-up, 11 (3.0%) of which were from cardiac causes. Actuarial survival rate was 85.2% at 10 years after surgery. The 10 year-survival rate was similar for patients with single, double, triple vessel disease, and left main trunk disease (94.5%, 83.7%, 75.1% and 89.1%, respectively). For patients with and without old myocardial infarction, the 10 year-survival rate was significantly different (75.4% and 93.3%, respectively) (p less than 0.005). In order to detect which factors of preoperative cardiac function among cardiac index, LV end-diastolic pressure, LV end-diastolic volume index, LV end-systolic volume index, and LV ejection fraction influenced the long-term prognosis, multivariant regression analysis was performed. Only LV end-systolic volume index was a significant factor, and the discriminative point was 50 ml/m2. For patients with LV end-systolic volume index less than 50 ml/m2 and greater than or equal to 50 ml/m2, the 10 year-survival rate was significantly different (88.3% and 32.9%, respectively) (p less than 0.005). In conclusion, the most significant factor influencing longterm prognosis after coronary artery bypass surgery was left ventricular end-systolic volume, indicating the importance of preventing preoperative dilatation of left ventricle.
