Surgical therapy for evolving myocardial infarction: Results in 138 patients.

One hundred thirty-eight selected patients underwent emergency coronary artery revascularization as the treatment for early evolving myocardial infarction. Low early and late (3.6 and 2.9%) mortality and morbidity up to 54 months, with favorable post surgical hemodynamic improvement demonstrates the operability with beneficial results in selected patients with early evolving myocardial infarction.
