The Efficacy of the Intima-media Thickness (IMT) to Predict Cardiovascular Disease in Vasculogenic Erectile Dysfunction Patients / 대한비뇨기과학회지

ABSTRACT

PURPOSE: Erectile dysfunction (ED) is associated and might be one of the first signs of cardiovascular disease (CVD). We aimed to assess whether men with vasculogenic ED have an increased risk of CVD by evaluating the relationship between erectile function and the intima-media thickness (IMT) of the common carotid arteries. MATERIALS AND METHODS: A total of 40 men were divided into 4 groups according to their erectile function as evaluated by the International Index of Erectile Function (IIEF)-15 and the presence of vascular risk factors (VRF). The risk free (RF) group (n=10) included men with ED and no evidence of VRF, the low-risk (LR) group (n=10) included the vasculogenic ED subjects who were overweight or dyslipidemic, and high-risk (HR) group (n=10) consisted of ED subjects with hypertension or diabetes. An age-matched healthy group without ED served as the control (n=10). Blood pressure, height, weight, the lipid profile and the IMT of the carotid arteries were evaluated. RESULTS: The control group and the vasculogenic ED groups showed significant differences in the IIEF scores and IMT (p<0.05). Spearman's test of the entire subjects revealed a significant correlation between the severity of ED and IMT (p<0.01), which was not present in the control group (p=0.523). However, a significant correlation of the severity of ED and IMT was found in the groups with ED (p<0.05). In addition, the evaluated parameters of the control group and the RF group revealed no significant difference except for the IIEF scores. CONCLUSIONS: Our results suggest that ED might be a prodrome of cardiovascular diseases. Thus, screening on cardiovascular risk factors and taking preventive measures are considered in ED patients, especially if the ED is severe.
