Purpose: Endothelial cell activation (ECA) is an initiating event in atherosclerosis. Biochemical measures of ECA were evaluated in patients with erectile dysfunction (ED) associated or not associated with cardiovascular risk factors (VRFs) to assess whether ED is a sentinel of atherosclerosis. Materials and Methods: Circulating soluble P-selectin, intercellular adhesion molecule-1, vascular cell adhesion molecule-1 and endothelin-1 concentrations were assessed in 45 men with ED but no VRFs, 45 men with ED associated with VRFs and 25 healthy men. Ultrasound intima-media thickness of carotid arteries and pharmacologically stimulated peak systolic velocity of cavernous arteries were used to assess vascular damage. Results: Measures of ECA were higher in men with ED but no VRFs than in controls (p 0.01) and all were comparable among groups of men with ED. Levels of endothelin-1 in men with ED and no VRFs versus healthy men of the same age resulted in the best independent predictor for ED after adjusting for the confounding effect of increased body mass index and smoking (OR 5.37, 95% CI 2.12 to 19.70). Intima-media thickness of carotid arteries was comparable in controls and in men with ED but no VRFs, and ruled out the bias of overt damage of large arteries in the latter. Peak systolic velocity of cavernous arteries excluded vasculogenic ED in the majority of patients with no VRFs. Conclusions: Increased biochemical measures of ECA were associated with ED independent of coexisting VRFs and overt vascular damage, suggesting that ED is a sentinel of early atherosclerosis.

Abstract

Purpose: Endothelial cell activation (ECA) is an initiating event in atherosclerosis. Biochemical measures of ECA were evaluated in patients with erectile dysfunction (ED) associated or not associated with cardiovascular risk factors (VRFs) to assess whether ED is a sentinel of atherosclerosis. Materials and Methods: Circulating soluble P-selectin, intercellular adhesion molecule-1, vascular cell adhesion molecule-1 and endothelin-1 concentrations were assessed in 45 men with ED but no VRFs, 45 men with ED associated with VRFs and 25 healthy men. Ultrasound intima-media thickness of carotid arteries and pharmacologically stimulated peak systolic velocity of cavernous arteries were used to assess vascular damage. Results: Measures of ECA were higher in men with ED but no VRFs than in controls (p 0.01) and all were comparable among groups of men with ED. Levels of endothelin-1 in men with ED and no VRFs versus healthy men of the same age resulted in the best independent predictor for ED after adjusting for the confounding effect of increased body mass index and smoking (OR 5.37, 95% CI 2.12 to 19.70). Intima-media thickness of carotid arteries was comparable in controls and in men with ED but no VRFs, and ruled out the bias of overt damage of large arteries in the latter. Peak systolic velocity of cavernous arteries excluded vasculogenic ED in the majority of patients with no VRFs. Conclusions: Increased biochemical measures of ECA were associated with ED independent of coexisting VRFs and overt vascular damage, suggesting that ED is a sentinel of early atherosclerosis.
