Clinical significance of erectile dysfunction developing after acute coronary event: exception to the rule or confirmation of the artery size hypothesis?

The Prevalence of Erectile Dysfunction and Its Association with Cardiovascular Risk Factors in Patients after Myocardial Infarction

Background and Objectives: This study estimates the prevalence and severity of erectile dysfunction and its association with cardiovascular risk factors in patients after a myocardial infarction. Materials and Methods: This study included men aged 35-80 years, diagnosed with myocardial infarction and examined in the Department of Preventive Cardiology of Vilnius University Hospital Santaros Klinikos between 2016 and 2020. Anthropometric characteristics, blood pressure, lipid profile, blood glucose levels and prevalence of cardiovascular risk factors were evaluated. The International Index of Erectile Function-5 was used to assess patients' erectile function. Results: A total of 171 patients were analysed. The mean age was 57.6 ± 8.8 years. Of the patients, 42.1, 25.1 and 11.7% had three, four and five established cardiovascular risk factors, respectively. Of the patients, 100% were diagnosed with dyslipidaemia, 90.0%-arterial hypertension, 14.6%-diabetes, 23.3%-smoking, 43.7%-positive familial history and 54.5%-insufficient physical activity. The overall prevalence of erectile dysfunction was 62%. It was scored mild in 37.4%, mild-to-moderate-15.2%, moderate-5.3% and severe in 4.1% of the patients. The mean age was significantly different between severity groups (p < 0.001). The study demonstrated a negative correlation between age and total score of the questionnaire (r = -0.308, p < 0.001). Arterial hypertension was more frequent in the patients with erectile dysfunction (p = 0.02). Other cardiovascular risk factors were distributed similarly. Conclusions: Erectile dysfunction is common in patients after a myocardial infarction and its severity is age dependent. The prevalence of cardiovascular risk factors is high, with arterial hypertension significantly more frequent in patients with erectile dysfunction.

Update of the position paper on arterial hypertension and erectile dysfunction

: Sexual health is an integral part of overall health, and an active and healthy sexual life is an essential aspect of a good life quality. Cardiovascular disease and sexual health share common risk factors (arterial hypertension, diabetes mellitus, dyslipidemia, obesity, and smoking) and common mediating mechanisms (endothelial dysfunction, subclinical inflammation, and atherosclerosis). This generated a shift of thinking about the pathophysiology and subsequently the management of sexual dysfunction. The introduction of phosphodiesterase type 5 inhibitors revolutionized the management of sexual dysfunction in men. This article will focus on erectile dysfunction and its association with arterial hypertension. This update of the position paper was created by the Working Group on Sexual Dysfunction and Arterial Hypertension of the European Society of Hypertension. This working group has been very active during the last years in promoting the familiarization of hypertension specialists and related physicians with erectile dysfunction, through numerous lectures in national and international meetings, a position paper, newsletters, guidelines, and a book specifically addressing erectile dysfunction in hypertensive patients. It was noted that erectile dysfunction precedes the development of coronary artery disease. The artery size hypothesis has been proposed as a potential explanation for this observation. This hypothesis seeks to explain the differing manifestation of the same vascular condition, based on the size of the vessels. Clinical presentations of the atherosclerotic and/or endothelium disease in the penile arteries might precede the corresponding manifestations from larger arteries. Treated hypertensive patients are more likely to have sexual dysfunction compared with untreated ones, suggesting a detrimental role of antihypertensive treatment on erectile function. The occurrence of erectile dysfunction seems to be related to undesirable effects of antihypertensive drugs on the penile tissue. Available information points toward divergent effects of antihypertensive drugs on erectile function, with diuretics and beta-blockers possessing the worst profile and angiotensin receptor blockers and nebivolol the best profile.

Do Urologists Really Recognize the Association Between Erectile Dysfunction and Cardiovascular Disease?

INTRODUCTION

Erectile dysfunction (ED) and cardiovascular diseases (CVDs) share many common risk factors. ED could be a strong independent predictive factor of CVDs. Furthermore, the treatment of ED had been shown to be beneficial for cardiovascular diseases. However, the association between ED and CVDs has been reported scarcely in the literature.

AIM

To investigate urologists' perception, diagnosis, and treatment of CVDs in patients with ED.

METHODS

The study was conducted as a prospective study from November 2018 through February 2019, including urologists aged 18-64 years. All participants completed a survey of the knowledge of ED via an online questionnaire platform in 7 WeChat groups of urologists. WeChat is the most popular multipurpose messaging and social media in China.

MAIN OUTCOME MEASURE

The main outcomes were the answers that urologists chose or filled.

RESULTS

449 urologists were included. Most of participants (375, 83.5%) agreed that CVDs are associated with ED. Only 231 participants (51.4%) thought ED was an independent disorder. The awareness of the association between ED and CVDs is significantly higher among male urologists than their female counterparts. Although 378 (83.6%) participants believed that the progression of these 2 diseases was consistent, only 181 (44.9%) would do conjoined assessment of both CVDs and ED. In addition, most urologists only considered conventional treatment, such as psychological intervention (341, 75.4%) and phosphodiesterase type 5 inhibitor (PDE5i) therapy (318, 70.4%) for their patients, whereas 339 urologists (88.3%) claimed that they would treat CVDs in patients with both ED and CVDs. 344 (76.6%) urologists showed some concerns over PDE5is.

CONCLUSION

Urologists' assessment of CVDs in patients with ED was disappointing especially among young and female urologists or those working in underserved areas. Besides, the urologists' treatments of ED were not updated, and their attitudes toward the safety and effectiveness of PDE5is for CVDs were not optimistic. Li D, Li X, Peng A, et al.

Association between coronary heart disease and erectile dysfunction in Chinese Han population

To investigate the association between coronary heart disease (CHD) and erectile dysfunction (ED) in Chinese Han population. Patients who went to the andrological out-patient clinic of our hospital between August 1, 2015 and May 1, 2016 and met all eligible criteria were enrolled in this study. The patients diagnosed as ED using self-administered International Index of Erectile Function-5 (IIEF-5) questionnaire were considered as case group and others were considered as control. The cases were categorized as mild, moderate, and severe ED. Subjects were interviewed for the history of CHD. Uni- and multivariate logistic regression models were used to calculate odds ratios (ORs) and corresponding 95% confidence intervals (CIs) using the SPSS 18.0 software. A total of 240 participants (56 ED patients and 184 controls) were enrolled. CHD prevalence was higher in cases without statistical significance (OR = 1.20, 95%CI = 0.63-2.29; p = 0.58). Results of adjusted analysis also showed a non-significantly increased risk (OR = 1.25, 95%CI = 0.55-2.85; p = 0.59). Stratified analysis by severity of ED revealed similar results. This study suggests no significant association exists between CHD and ED in Chinese Han population.

Association between serum fetuin-A level and erectile function

Recent studies have shown that ED is an early symptom of atherosclerosis. Fetuin-A, a glycoprotein secreted by the liver, kidneys and choroid plexus, has been linked to systemic fibrosis and calcification in human and rat studies. Deficiency of this compound may play a role in atherosclerosis and cardiovascular disease progression. The aim of the study was to examine whether serum fetuin-A level is related to erectile function or severity of ED. Sixty ED patients without cardiovascular disease were assigned to one of the three groups (mild, moderate or severe ED) depending on ED severity. Twenty healthy volunteers were included as the control group. The International Index of Erectile Function-5 questionnaire was used to measure erection quality in all four groups. Mean age, body mass index, total testosterone, low- and high-density lipoprotein cholesterol, and triglyceride levels did not significantly differ between the three erectile dysfunction and control groups (P > 0.05). The group with severe ED had a significantly lower mean fetuin-A level than the mild ED and control groups. For both mild and moderate ED groups, the mean serum fetuin-A level was significantly lower in comparison with the control group (P < 0.001). Serum fetuin-A level may be used as a supplemental biochemical parameter in preliminary evaluation of ED.

Cardiovascular disease and male sexual dysfunction

Erectile dysfunction (ED) is a form of sexual dysfunction that is estimated to affect > 30% of men between the ages of 40 and 70. As a result of an improved understanding about the pathophysiology of ED and improved treatment options, an increasing number of men are presenting for evaluation than several decades ago. In fact, many of these men are visiting their health care professional for the first time with ED as their primary complaint. Most of these men are unaware of the link between ED and cardiovascular disease (CVD).
