One hundred twenty-eight patients with myocardial infarction who underwent operation for myocardial revascularization and 147 patients who received medical therapy were followed up for up to 6 years: all patients had received treatment with intravenous streptokinase. In the surgical group, 91.5% of the patients had the region related to the infarction revascularized, and in 82.8% of them the mammary artery was used. Statistically significant differences were not detected between the groups according to infarct size, clinical features, and left ventricular ejection fraction. However, there was a higher risk in the surgical group, as compared with that in the medical group, in terms of anatomic characteristics: 99.2% versus 77.1% of the patients showed more than 70% residual obstruction at the "culprit" coronary artery (p < 0.001, 95% confidence interval 14.1% to 30.1%) and 76.8% versus 40.7% showed multivessel coronary disease (p < 0.001, 95% confidence interval 23.7% to 48.5%). In-hospital survival was 95.3% in the surgical group and 89.1% in the medical group (p = 0.096, 95% confidence interval -0.2% to 12.6%). Significantly higher survivals were obtained for the surgical group both during the first (93% +/- 2.3% versus 80.3% +/- 3.3%, p = 0.005) and the sixth (86.4% +/- 3.4% versus 68.4% +/- 4.3%, p = 0.003) year of follow-up. Statistically significant differences were also obtained when in-hospital deaths were excluded. A Cox regression model with 13 variables showed that only age (p = 0.0422) and medical treatment (p = 0.0194) correlated independently with mortality. It is concluded that in this nonrandomized study, operation led to a significantly higher survival both on a medium- and long-term basis, when compared with that obtained for patients receiving medical therapy.
