Abstract
Evidence is accumulating in favor of classifying erectile dysfunction (ED) as a vascular disorder. There are three main clinical scenarios in which ED and coronary artery disease (CAD) may coexist: the patient with ED who later develops CAD, the patient with overt CAD who is casually found to have ED, and the patient with acute coronary syndrome who has normal sexual function. This study presents three cases and discusses a “putative” pathophysiological mechanism underlying all these clinical presentations. Further studies, coupling functional and structural changes of coronary circulation with those of penile (i.e., dynamic penile test) circulation in each of these situations are mandatory to support this hypothesis.
