Figure 6.

A graphic depiction of the artery size hypothesis in a patient (as in Figure 2) with acute myocardial infarction at a 6 months follow-up time interval when erectile dysfunction developed. Progression of atherosclerosis led to a significant stenosis at the level of penile circulation. The same plaque burden was accommodated in larger arteries (right and left circumflex coronary arteries) without inducing flow-limiting stenosis. CAD: coronary artery disease; CVD: cardiovascular disease; ED: erectile dysfunction.
