Incidence of changes and predictive factors for sexual function after coronary stenting

Abstract

The study was aimed at determining the incidence of changes in sexual function and identifying the possible associated variables of erectile dysfunction (ED) in coronary artery disease (CAD) patients undergoing coronary stenting. Four hundred and sixty-seven patients were retrospectively contacted with a questionnaire regarding sexual function from 6 months pre-stenting to 6 months post-stenting by telephone follow up. Univariate analyses were used to determine prognostic variables. ED changed following stenting in CAD (P < 0.05), in acute coronary syndrome (ACS) (P > 0.05) and in chronic coronary syndrome (CCS) (P < 0.05). Sexual activity was not resumed in 8.1%, was unchanged in 33.8%, increased in 0% and decreased in 58.0%. The average frequency of sexual activity decreased every month in CAD (P < 0.05), in ACS (P < 0.05) and in CCS (P < 0.01) after undergoing coronary stenting respectively. The mean time interval between the onset of ED and CAD was 33 months. Resuming sexual activity after stenting varied from 2 weeks to 30 months. Significant predictors of ED after coronary stenting were mean age, diabetes mellitus, 2,3-vessel disease or current smoking status. It was concluded that coronary stenting had a significant incidence of ED. Mean age, diabetes mellitus, 2,3-vessel disease or current smoking status showed to be the main variables associated with ED. Attempts to improve individual secondary prevention outcomes (controlling serum glucose and smoking cessation) should be designed.
