Abstract
• A consecutive series of 4,522 patients who received aortocoronary bypass (ACB) from October 1969 through December 1974 has been analyzed with respect to cumulative (actuarial) survival, cause of late death, and late postoperative complications. Through December 1973, 2,676 patients received ACB alone. Cumulative survival was 85.9% for five years. Late cumulative mortality averaged 2.7% per year. Causes of death were myocardial in origin in only 60.4% of the patients. Late complications of nonfatal myocardial infarction occurred in 4.1% of the patients, and congestive heart failure occurred in 10.2%. However, preoperative congestive heart failure was present in 25% of these subjects. Mortality in 1974 was 3.4% in patients who underwent ACB only, and 4.2% for all patients who received ACB procedures (1,478 patients). Comparison to previous medical data makes it appear that this surgery increased the actuarial survival over long-term follow-up.
