Purpose
To evaluate the impact of severe erectile dysfunction (ED) on future major adverse cardiovascular events (MACE) in men on dialysis.
Materials and Methods
This prospective cohort study included 71 men on dialysis. ED was assessed using the Sexual Health Inventory for Men (SHIM). Men were divided into the mild/moderate ED (SHIM score ≥8) and severe ED (SHIM score ≤7) groups. The primary endpoint was MACE-free survival. MACE was a composite of myocardial infarction, cardiovascular death, and stroke. The secondary endpoints were cardiac event-free survival and overall survival (OS). Moreover, the predictive abilities of severe ED for 5-year MACE, 5-year cardiac events, and 5-year overall mortality were evaluated.
Results
The median age and follow-up period of the included men were 64 years and 58 months, respectively. The median SHIM score was 4.0; all had a degree of ED, and 64.7% had severe ED. In the background-adjusted multivariable analyses, severe ED was not significantly associated with shorter MACE-free survival (hazard ratio [HR], 1.890; 95% confidence interval [CI], 0.533–6.706; p=0.324), cardiac event-free survival (HR, 2.081; 95% CI, 0.687–6.304; p=0.195), and OS (HR, 0.817; 95% CI, 0.358–1.863; p=0.630). Severe ED did not significantly improve the predictive abilities for 5-year MACE, 5-year cardiac events, and 5-year overall mortality (p=0.110, p=0.101, and p=0.740, respectively).
Conclusions
ED severity was not associated with shorter MACE-free survival, cardiac event-free survival, or OS, and ED severity could not improve the predictive abilities for these outcomes in men undergoing dialysis.
