Reduced Left Ventricular Diastolic Asynchrony after Captopril in Single Vessel Coronary Artery Disease

Impaired left ventricular diastolic function is often found preceding systolic functional abnormality in coronary artery disease. To assess whether captopril improves diastolic function, radionuclide ventriculography was performed before and 1 h after captopril administration in 10 stable effort angina patients with severe isolated stenosis of the left anterior descending coronary artery and in 8 controls. Resting global peak filling rate (PFR) was significantly (p
