Abstract/OtherAbstract:
AIMS: To determine whether idiopathic erectile dysfunction, in the absence of overt cardiovascular disease or cardiovascular risk factors, is associated with vascular or autonomic dysfunction. METHODS: We studied 49 men with ED (without known cardiovascular risk factors or disease) and 50 age-matched controls, aged 40-70 years. Macrovascular endothelial function was examined by brachial artery ultrasonography and microvascular function by venous occlusion plethysmography. Blood pressure measurement and electrocardiography were performed lying and standing, and the 30:15 RR ratio calculated. RESULTS: Body mass index, testosterone, fasting lipids and glucose did not differ significantly between groups. Standing pulse pressure was higher (50+/-1mm Hg versus 43+/-2mm Hg, p<0.004) and 30:15 RR ratio lower (0.97+/-0.01 versus 1.01+/-0.01, p<0.02) in the ED group. Flow-mediated dilatation of the brachial artery was not significantly different between groups. Flow debt repayment during forearm reactive hyperaemia was lower in the ED group (7.2+/-0.7 ml versus 9.5+/-0.8 ml per 100ml, p<0.02) than in controls. CONCLUSIONS: Men with idiopathic ED have evidence of endothelial dysfunction in forearm resistance vessels, increased pulse pressure and impaired heart rate variability. This supports the concept that erectile dysfunction is a predictor of cardiovascular dysfunction and a precursor of clinical cardiovascular disease.
