Five-year follow-up of patients undergoing coronary artery bypass.
Two hundred eighty-two patients who underwent coronary artery bypass operation between January, 1971, and July, 1972, were followed until the time of death or for 5 years after operation. The angina-free status progressively decreased during the period of follow-up but at 5 years 57% of the survivors were free from angina. The total (early and late) incidence of nonfatal myocardial infarction was 3.3 per 100 patient years of follow-up. Nine (3.2%) of the patients had a repeat coronary artery bypass operation within the first 5 postoperative years. The overall 5-year survival was 86.9%. The expected 5-year survival of the general population, matched by sex and age, is 90.7%. Five-year survival was 97% for single-vessel disease, 87% for double-vessel disease, and 85% for triple-vessel disease.
