Erectile dysfunction (ED) shared risk factors with coronary artery diseases (CVD). Coronary artery bypass grafting (CABG) is the standard for surgical myocardial revascularization. Although there is an association between CAD and ED yet most cardiologists do not ask about ED. The European System for Cardiac Operative Risk Evaluation (EuroSCORE) gives appropriate weight to various risk factors in adult cardiac operations. We herein evaluate using the EuroSCORE in predicting the sexual function in patients undergo 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 and finally by the European System for Cardiac Operative Risk Evaluation (EuroSCORE). Six months after surgery all patients were revaluated according to the same preoperative procedures.

The EuroSCORE results showed that 56/ 100 patients were low risk patients while 44/ 100 were medium risk patients.

Preoperatively the EuroSCORE showed significant negative correlation to the IIEF-5 score (r = -0.229, p<0.05). Moreover low risk patients had significantly higher IIEF-5 scores compared to medium risk patients (p<0.05). Postoperatively EuroSCORE results showed a significant relationship to the change in erectile function after surgery. In low risk patients 26/56 (46.4%) reported IIEF-5 improvement after surgery while only 10/44 medium risk patients (22.7%) reported IIEF-5 improvement after surgery. This difference was significant (p<0.05).

We can conclude that the EuroSCORE is a useful, quick and inexpensive tool for prediction of ED in patients who undergoing CABG.
