Massachusetts Male Aging Study’ and the ‘Cologne Male Survey’ revealed an association of cardiovascular risk factors and ED with a prevalence of 30–75%of ED in cardiovascular high-risk patients.

Coronary artery bypass grafting (CABG) is the gold standard for surgical myocardial revascularization. The published studies discussing the predictor factors of the future sexual function following CABG is limited. We herein evaluate the impact of vascular risk factors on the future sexual functions after CABG.

The study included 100 patients who underwent CABG. The patients were evaluated by abridged form of International Index of Erectile Function questionnaire (IIEF-5), Pharmaco-Penile Duplex Ultrasound. The patients were underwent CABG, six months later the erectile function of all patients was revaluated according to the same preoperative procedures.

Preoperatively there was a significant correlation between age, diabetes mellitus, hypertension, hyperlipidemia and IIEF-5 scores (p<0.01). Moreover the frequency of the intercourse in the same groups and the IIEF-5 was significant (p<0.001). IIEF-5 scores of patients with two or more risk factors were significantly lower than patients with no risk factor or with one risk factor (p<0.001). Moreover, the of frequency of intercourse per month of patients with two or more risk factors was significantly lower than patients with no risk factor or with one risk factor (p< 0.01),

Diabetes mellitus showed a positive correlation with the change in IIEF-5 scores after surgery (p< 0.05).

Only DM may predict the future sexual function in patients undergo CABG.
