Is there a relationship between severity of coronary artery disease and severity of erectile dysfunction?

摘要

Introduction The correlation between erectile dysfunction (ED) and coronary artery disease has been emphasized and ED has been recognized as a potential independent risk factor and/or predictor of coronary artery disease (CAD). We evaluated the association between the number of occluded coronary arteries in myocardial infarction (MI) patients with the severity of ED, and investigated the influence of related risk factors in our study group. Materials and Methods 183 male patients who underwent coronary angiography because of acute MI from November 2009 to May 2011 were included. Following the stabilization of patients after the treatment, each patient was evaluated for erectile functionality. Risk factors such as age, diabetes, smoking, waist circumference, hypertension, and hematologic parameters were recorded. Results Among 183 patients with a mean age of 55.2 years who underwent coronary angiography due to acute MI, 100 (54.64%) had ED, while the ED rate was 45.36% (44/97) in cases of single-vessel disease, 64.5% (31/48) in cases of two-vessel disease, and 65.7% (25/38) in cases of three-vessel disease. The mean IIEF score was 24.2 ± 4.3, 20.4 ± 4.9 and 20.5 ± 4.2 for single or two or three-vessel disease, respectively. The presence of hypertension aggravated ED only in patients with three-vessel disease and increased total and LDL cholesterol levels in patients with single-vessel or two-vessel disease were accompanied by significantly decreasing IIEF scores. Conclusion The severity of ED correlated with the number of occluded vessels documented by coronary angiography, in male patients with acute myocardial infarction. In addition, the presence of hypertension had a significant influence over erectile function only in patients with three-vessel occlusion.
