Acute evolving myocardial infarction. A surgical emergency.

This is a report of 342 cases of acute evolving myocardial infarction treated with prompt coronary artery bypass. Myocardial infarction results from a time-related sequence of ischemic pathophysiological changes. The first hours constitute a rapidly progressive event. Prompt surgical revascularization partially prevents impending myocardial necrosis; occasionally it may even prevent it completely. The results are limited infarct size, decreased mortality and morbidity, and a striking absence of the complications associated with conventional therapy (ventricular aneurysm or perforation and septal and papillary muscle rupture).
