    Abstract:
    PURPOSE: The aim of this study was to investigate the connection between erectile dysfunction (ED) and cardiovascular diseases and to test a novel visual-scale questionnaire (VEF) we propose for the assessment of erectile function. SUBJECTS AND METHODS: Erectile function was assessed in 170 male cardiovascular patients under the age of 70 by the use of several self-administered questionnaires: the International Index of Erectile Function-5 (IIEF-5); the Massachusetts Male Aging Study questionnaires (MMAS Sexual Activity Questionnaire and MMAS Single Question), and finally, VEF. RESULTS: Patients’ mean age was 55.65 ± 9.97 y. The most common indications for hospitalization were coronary artery disease (CAD) (n = 82, 48%), and decompensated chronic heart failure (n = 30, 18%). The prevalence of ED as determined by IIEF-5 was 58% (n = 99). Patients with ED were on average 5.7 years older (P = 0.0001), had a higher frequency of diabetes (by 19%, P < 0.01), and a somewhat higher level of uric acid (by 72 μmol/l, P < 0.01). Results of the VEF correlated significantly with those of other questionnaires. Three different machine learning algorithms demonstrated a greater accuracy of VEF than IIEF-5 and MMAS Sexual Activity Questionnaire in predicting ED severity. CONCLUSION: ED is highly prevalent among cardiovascular patients. The Visual Scale Erectile Function questionnaire (VEF) is a simple and valid tool, suitable for quick screening of this condition.
