RESUMO
INTRODUCTION: Erectile dysfunction (ED) represents an independent and/or predictive risk factor for coronary heart disease according to many studies. The aim of our study is to determine the prevalence and risk factors associated with erectile dysfunction in coronary patients confirmed by coronary angiography. MATERIAL AND METHOD: We conducted a descriptive and analytical cross-sectional study. A total of 60 patients were included with proven atheromatous coronary lesions after coronary angiography. The study period was from June 1, 2020 to February 29, 2021. After assessment of erectile status based on the short version of the International Index of Erectile Function (IIEF-5). Measures of association were adjusted odds ratios and odd ratios with their confidence intervals. Multivariate analysis was conducted using logistic regression. Only patients with erectile insufficiency underwent penile pharmocodoppler. RESULTS: The mean age was 56 ± 8.4 years with extremes of 28 and 65 years. Erectile status was classified according to the IIEF-5 score as follows: severe ED (32%), moderate (13%), mild (15%) and normal erectile function (40%). The time to onset of ED was> 2 years in 69.4% of cases before the onset of coronary artery disease with a mean time of 2.37 years ± 1.29. In 20% of the cases, the patients were already on treatment before the erectile disorder, 65% undergoing treatment after the erectile disorder and 15% had no undergoing treatment. The main factors associated with ED were: high blood pressure (OR = 7; p = 0.0007), dyslipidemia (OR = 4.86; p = 0.004), diabetes (OR = 3.8; p = 0.02), obesity (OR = 4, 45; p = 0.02) as well as beta blockers (OR = 5.3; p = 0.004), calcium channel blockers (OR = 4.5; p = 0.004) and angiotensin-converting enzyme inhibitors (OR = 4.3; p = 0.008). The vascular cause clearly dominates (95%) of which 61% arterial mechanism, 17% mixed and 17% venous mechanism. The factor associated with a decrease PSVpi was the diabetes (OR = 28; p = 0.01). In multivariate analysis, no factor was statistically associated with ED or decrease in PSVpi. CONCLUSION: Isolated ED appears as an early marker of generalized endothelial dysfunction. Hence the advantage of systematic screening, especially in subjects at risk of cardiovascular disease.
