Erectile dysfunction severity as a predictor of left main and/or three-vessel disease in acute coronary syndrome patients

BACKGROUND: Coronary artery disease (CAD) is a leading cause of morbidity and death. Early diagnosis of patients with left main and/or three-vessel disease (LM/3VD) among acute coronary syndrome (ACS) patients is beneficial. The relation between erectile dysfunction (ED) and cardiovascular diseases was previously noticed. The aim of our work was to find out if the severity of ED could predict the presence of LM/3VD in ACS patients. PATIENTS AND METHODS: Eighty-five male patients with ACS were included in the study. Clinical assessment, estimation of international index of erectile function (IIEF) score, and coronary angiography were performed in all patients. Gensini score was calculated to assess the severity of CAD. Based on IIEF score, the patients were divided into two groups: Group 1: patients with mild or no ED (IIEF score ≥17), Group 2: patients with moderate or severe ED (IIEF score <17). RESULTS: Patients with IIEF score <17 had significantly higher prevalence of LM CAD (4.3% versus 18.4%, p = 0.035), 3VD (17% versus 39.5%, p = 0.021) and LM/3VD (21.3% versus 55.3%, p = 0.0012), as well as higher mean Gensini score (23.5 ± 10.8 versus 34.1 ± 12.7, p = 0.0001). The independent predictors of LM/3VD in order of significance were: age, heart rate, IIEF <17, Killip class >1, and ST-depression or ST-elevation in lead aVR ≥1 mV. There was a significant negative correlation between IIEF score and Gensini score (r = −0.383, p = 0.0003). CONCLUSION: The presence of moderate or severe ED in men with ACS is associated with higher Gensini score and more incidence of LM/3VD. IIEF score <17 was an independent predictor of LM/3VD.
