Can we use surrogate vascular beds for evaluating endothelial function of the coronary vasculature in patients with cardiac allografts?

Abstract

a landmark study in vascular biology almost 30 years ago described the essential role of the endothelium as a mediator of vasodilator response to acetylcholine ([4][1]). Since then many studies have been performed in an effort to understand this complex organ. Endothelial function plays a pivotal
