Coronary bypass grafting in early stages of acute myocardial infarction

Acute coronary bypass surgery was performed in four patients with early anterior myocardial infarction due to severe proximal stenosis of the left anterior descending artery. Improvemnet of left ventricular anteroapical wall contraction was detected at the completion of the operation, in the early postoperative phase, and six to 18 months after surgery. It is concluded that critically ischaemic myocardium was salvaged by revascularization.
