Erectile Dysfunction is Predictive of Endothelial Dysfunction in a Well Visit Population.

Area of Science:

• Cardiovascular Health
• Urology
• Preventive Medicine

Background:

• Endothelial dysfunction is a precursor to erectile dysfunction and is linked to adverse cardiac events.
• Understanding the prevalence of these conditions and related comorbidities is crucial for risk assessment.

Purpose of the Study:

• To determine the prevalence of erectile dysfunction, endothelial dysfunction, and associated comorbidities in men undergoing wellness screening.
• To investigate the relationship between erectile dysfunction, endothelial dysfunction, and risk factors like obesity.

Main Methods:

• 205 men were assessed using peripheral arterial tonometry for endothelial dysfunction and a health screening questionnaire.
• Endothelial dysfunction was defined as a reactive hyperemia index score of 1.67 or less.
• Statistical analyses included Student t-test, Fisher exact test, and univariate/multivariable analyses.

Main Results:

• 47 out of 205 men reported erectile dysfunction.
• Men with erectile dysfunction had significantly lower reactive hyperemia index scores (1.63 vs 1.87, p=0.001).
• Endothelial dysfunction was more prevalent in men with erectile dysfunction (55% vs 36%, p=0.027). Erectile dysfunction and obesity independently predicted endothelial dysfunction (OR 2.45, p=0.02 and OR 2.08, p=0.01).

Conclusions:

• Erectile dysfunction and obesity are independent predictors of endothelial dysfunction in middle-aged men.
• Endothelial dysfunction is a known risk factor for long-term adverse cardiac events.
• These findings underscore the importance of screening for endothelial dysfunction in men presenting with erectile dysfunction or obesity.
