Early intervention in case of cardiovascular disease can prevent the onset of heart attack and stroke in patients. Erectile Dysfunction could be an early indicator of these cardiovascular diseases (CV). The findings of this study are further discussed in the Journal of Vascular Medicine.
In addition to being an important health and quality of life issue for men, erectile dysfunction has long been associated with CV disease. Risk factors for erectile dysfunction and CV disease are similar - including older age, smoking, obesity, and diabetes, among others. Also, multiple overlapping mechanisms lead to the development of both erectile dysfunction and CV disease.
In the article entitled "The relationship of erectile dysfunction and sub clinical cardiovascular disease: A systematic review and meta-analysis," Dr. Chukwuemeka Osondu, Bryan Vo, Ehimen Aneni, and colleagues sought to establish erectile dysfunction as a simple and effective marker of underlying sub clinical CV disease.
The authors conducted a systematic review and meta-analysis of 28 studies that examined the link between erectile dysfunction and measures of early CV disease. They report a significant association of erectile dysfunction with impaired endothelial function (measured by brachial flow-mediated dilation using ultrasound), a marker of the ability of blood vessels to relax that is an early event in vascular disease development.
In addition, the authors report that erectile dysfunction was associated with increased carotid intimal medial thickness (carotid IMT), an early manifestation of atherosclerosis. The results for the association of erectile dysfunction and coronary artery calcium scoring were inconclusive due to a small number of studies with limited sample size. The authors identify this as an area in need of future study.
As explained by the authors, "Our study findings indicate that [young] men [with erectile dysfunction] are at greater risk of having identifiable subclinical CV disease and will benefit from an active CV disease work-up...Our study supports a more aggressive CV disease risk assessment and management for persons with erectile dysfunction, including young men who may otherwise be categorized as low risk due to their young ages."
In an accompanying editorial, Dr. Naomi Hamburg and Dr. Matt Kluge (Boston University) agree: "The presence of erectile dysfunction portends a higher risk of future cardiovascular events, particularly in intermediate-risk men, and may serve as an opportunity for intensification of cardiovascular risk prevention strategies." They add "The findings add to the growing evidence supporting additional trials to determine the clinical impact of erectile dysfunction screening and the appropriate cardiovascular directed evaluation and treatment of men with erectile dysfunction."
