Sildenafil Improves Erectile Function in Men with Chronic Heart Failure

Patients with Chronic Heart Failure (CHF) have been shown to have enhanced risk of Erectile Dysfunction (ED) due to low cardiac output, endothelial dysfunction, medications, co-morbid conditions, and psychogenic factors.. The present study aimed to evaluate the effects of sildenafil on erectile function of patients with stable CHF using the abridged 5-item version of the International Index of Erectile Function (IIEF-5)..Patients and Using convenience sampling, 222 sexually-active adult males with NYHA class I-III stable CHF were included in this cross-sectional study. All the patients filled out the IIEF-5 questionnaire, in which they were required to score the five domains of male sexual function, including erectile function, orgasm function, sexual desire, intercourse satisfaction, and overall satisfaction. All the analyses were performed using the SPSS statistical software (v. 19) and P < 0.05 was considered as statistically significant.. In our sample, the patients’ mean age was 47.14 ± 11.86 years, their mean left ventricular ejection fraction was 20% (15% - 25%), and the prevalence of ED was 70.3%. In addition, severe, moderate, mild to moderate, and mild ED were seen in 57%, 17%, 7%, and 19% of the patients with ED, respectively. ED was significantly more prevalent in the patients with ischemic heart failure compared to those with idiopathic dilated cardiomyopathy (84.68% vs. 55.85%, P < 0.001). Moreover, the prevalence of ED was significantly lower in the patients taking sildenafil compared to the other group (42.85% vs. 82.89%, P < 0.001).. Sildenafil appears to provide satisfactory results toward improving sexual function in patients with CHF..
