Abstract

Coronary endothelial dysfunction has been demonstrated in patients with symptomatic heart failure. Furthermore the endothelium has been implicated in the pathogenesis of cardiomyopathy in patients with normal coronary angiograms and no other known causes of heart failure. Herein we describe an asymptomatic patient with an early cardiomyopathy and abnormal coronary endothelial function. There was no evidence for coronary disease by both angiography and intravascular ultrasound. Epicardial coronary artery vasoconstriction and a decrease in coronary blood flow was noted during the intracoronary infusion of graded concentrations of acetylcholine. This case demonstrates that endothelial dysfunction occurs in the setting of asymptomatic left ventricular dysfunction and highlights the potential importance of the endothelium in the early development of heart failure.
