title: The risk of coronary bypass surgery for patients with postinfarction angina.
abstract: Three hundred consecutive patients who developed unstable postinfarction angina requiring isolated coronary artery bypass from 1982 through 1987 were analyzed. Hospital mortality was 5%; 15 (5.5%) additional late deaths occurred during the 69-month follow-up period (mean follow-up, 23.3 months). Significant independent predictors of perioperative mortality by univariate analysis were ejection fraction (p = 0.004); existence of an anterior, transmural infarction (p = 0.0001); and the requirement for preoperative intra-aortic balloon counterpulsation (p = 0.001). By multivariate analysis, only the occurrence of an anterior, transmural infarction (p = 0.001) and the preoperative use of an intra-aortic balloon pump (p = 0.004) were significant independent predictors of mortality. Actuarial survival in this group ranged from 96 +/- 1% at 1 year to 88 +/- 4% at 5 years.
