High Cholesterol and Erectile Dysfunction Connection

Pathophysiological Connection

• High cholesterol contributes to erectile dysfunction through endothelial dysfunction and atherosclerosis that affects both coronary arteries and penile vasculature 2, 1
• The attainment and maintenance of erections requires good arterial blood inflow and efficient venous outflow, both of which can be compromised by hypercholesterolemia 3, 4

Evidence Supporting the Connection

• ED is now recognized as an early marker of cardiovascular disease, with a 2-5 year time window between ED onset and a coronary artery disease event 1, 5
• The Princeton III Consensus recommends that all men with organic ED should be considered at increased cardiovascular risk until proven otherwise 6, 7

Clinical Significance

• Men with ED have a significantly increased risk of cardiovascular disease, and ED can be an independent risk factor for cardiovascular disease 1, 6
• The severity of ED correlates with the extent of cardiovascular disease risk - more severe ED is associated with greater risk of major cardiovascular events 1, 7

Management Approach

• The American College of Cardiology and other guideline societies recommend assessing cardiovascular risk factors in men with ED, including hypercholesterolemia, hypertension, diabetes, obesity, and smoking history 2, 8
• Consider ED as an independent risk factor for cardiovascular disease, and treat hypercholesterolemia in men with ED to lower cholesterol levels and reduce cardiovascular risk 1, 6

Important Considerations

• ED may be particularly useful in assessing cardiovascular risk in younger men and minorities whose risk may be underestimated by traditional risk assessments 5
• When treating ED in patients with cardiovascular disease, ensure the patient's cardiac condition is stable enough for sexual activity 2, 9
