Emergency myocardial revascularization.

From 1969 to 1975, 175 patients with acute coronary insufficiency underwent emergency saphenous vein aorto-coronary bypass grafting (SVBG). The patients were divided into two groups: group I, unstable angina (165 patients) and group II, acute evolving myocardial infarction (ten patients). In group I, the hospital mortality was 8-4%, the incidence of post-operative myocardial infarction was 10-3%. Long-term follow-up was obtained for an average of 25 months, functional improvement was definite in the majority of the patients and actuarial survival curves show 87% patients alive at the end of 48 months. In group II, the hospital mortality was 30%; seven of ten patients had good results.
