Association of Multiple CardiOvascular Risk Factors and Erectile Function Across Europe

Overview

The purpose of the study is to evaluate the influence of cardiovascular risk factors, heart failure and cardiovascular drug therapy on erectile function in cardiovascular high-risk patients.

Association of cardiovascular risk factors and ED is likely due to an impairment of endothelial function resulting in a decreased activity of endothelial NO-synthase, which plays a major role in physiology of erection. Heart failure is also known to further contribute to endothelial dysfunction and hence, this could lead to erectile dysfunction. Study Objectives 1. Evaluation of the influence of cardiovascular risk factors and concomitant medication on erectile function in cardiovascular high-risk patients. 2. Evaluation of the role of heart failure on prevalence and severity of erectile dysfunction in men. 3. Long-term effects of cardiovascular drug therapy and cardiovascular diseases on erectile function. Study Design Male patients across Europe with cardiovascular diseases (CHD, PAD and heart failure) will be evaluated with a standardized questionnaire. Grade of erectile dysfunction will be assessed using an ED-score, generated from two different questionnaires. 1. IIEF-5 - (International Index of Erectile Function) 2. KEED - (Cologne Evaluation of Erectile Dysfunction) Primary Endpoint The primary endpoint is the sum score of the ED rating scale of the KEED (Kölner Erhebungsbogen zur Erektilen Dysfunktion, see Appendix 1). Erectile dysfunction is defined as reaching more than 17 points in the sum score. Secondary Endpoint The first secondary endpoint is the frequency of sexual activity and sexual desire. Another secondary endpoint contains satisfaction with sex life and general well-being. Men are defined as dissatisfied by answering "mixed" or "worse". Follow-Up: after 1 year, after 2 years.
