[Radionuclide ventriculographic assessment of cardiac function based on the analysis of cardiac reserve during dynamic exercise].

Abstract

To evaluate the contribution of myocardial contractility and preload to increase cardiac output during supine bicycle exercise, quantitative radionuclide ventriculography was performed at rest (R) and during peak exercise (Ex) in 43 patients with coronary artery disease (CAD) and 13 normal subjects. Myocardial contractility was estimated from the ratio of… (More)
