Coronary vasodilatory capacity is impaired in patients with dilated cardiomyopathy.

Abstract

Increases in wall stress because of left ventricular enlargement and/or alterations in coronary vasomotor tone might affect myocardial blood flow and vasodilatory capacity in patients with dilated cardiomyopathy. To test this hypothesis myocardial blood flow was measured at rest and during intravenous administration of dipyridamole (0.56 mg/kg) using… (More)
