Fifty-seven consecutive patients presenting with unstable angina pectoris or so-called pre-infarction angina were prospectively evaluated by clinical and angiographic studies. One patient died during angiography and another died of acute myocardial infarction 11/2 hours after cardiac catheterization. Forty-five patients had significant obstruction in two or three coronary arteries. The average left ventricular ejection fraction was 59 percent. Of 15 patients treated medically, 10 were potential candidates for surgery. One of these 10 died during hospitalization and 9 survived. The nine survivors were followed up for an average of 10 months; six reported symptomatic improvement, and one had an uncomplicated myocardial infarction 6 months after study. Aortocoronary saphenous vein bypass was performed in 40 patients, of whom 9 died during hospitalization and 31 survived operation. Of the 31 survivors, 1 had an uncomplicated myocardial infarction 9 months postoperatively; there were no late deaths in this group during a follow-up period averaging 16.7 months. Thirty of the 31 survivors reported marked symptomatic improvement, and 21 of these survivors were pain-free.
