Abstract

To investigate the prognostic importance of abnormal exercise left ventricular function on radionuclide angiography in the absence of significant angiographic coronary artery disease, 79 consecutive patients with these findings were followed up for a mean of 25 months (range 12 to 55). All patients had 1) an ejection fraction at rest ≥ 0.40, 2) an ejection fraction that decreased with exercise or peak exercise ejection fraction < 0.60, and 3) no significant coronary artery disease. The mean change in ejection fraction was a decrease of 0.07. In 63 patients (80%) the ejection fraction decreased during exercise; in 45 patients, it decreased by ≥ 0.05. Twenty patients (25%) had a peak exercise ejection fraction < 0.50. All patients were alive at follow-up study. One patient had a nonfatal myocardial infarction, and three patients were hospitalized for recurrent chest pain. No patient underwent coronary angioplasty or bypass surgery. The calculated infarction-free survival rate at 4 years by life table analysis was 97%. Patients with abnormal exercise radionuclide angiogram in the absence of significant angiographic coronary artery disease have an excellent short-term prognosis.
