ED and Heart Disease: Why This Symptom Is a Warning

Atherosclerosis is systemic. Plaque does not choose one artery; it deposits throughout the arterial tree, and endothelial dysfunction — the failure of blood vessel linings to produce enough nitric oxide — develops everywhere at once. What differs is when each artery becomes symptomatic, and that depends on its diameter.

If you present with erectile dysfunction and no obvious explanation, a good clinician will look at your cardiovascular risk before writing a prescription. If yours does not, ask. This is a reasonable, specific request.

• ✓Blood pressure — measured properly, ideally with home readings.
• ✓Fasting lipid profile.
• ✓HbA1c or fasting glucose to screen for diabetes and prediabetes.
• ✓Waist circumference and BMI.
• ✓Smoking status and alcohol intake.
• ✓A calculated 10-year cardiovascular risk score.
• ✓Family history of early heart disease.
• ✓Morning testosterone if libido is also reduced.

Depending on those results, a resting ECG or a stress test may follow. The purpose is not to alarm you — it is to catch a treatable process at the stage where treating it is easy.

For most people with stable cardiovascular disease, yes. Sexual activity with a familiar partner is generally comparable to moderate exercise — around the effort of climbing two flights of stairs or walking briskly.

The widely used rule of thumb is that a man who can manage two flights of stairs, or a brisk walk, without chest pain or undue breathlessness is at low risk during sex. Anyone who cannot should have a formal assessment first.

Certain groups should defer sexual activity until reassessed: unstable or refractory angina, uncontrolled hypertension, a recent heart attack or stroke, decompensated heart failure, significant untreated arrhythmia, or severe valve disease.

The good news is that the interventions overlap almost completely. Everything that improves endothelial function improves both erections and cardiovascular outcomes.

• Exercise — the best-supported non-drug treatment for ED and the cornerstone of cardiac risk reduction. See lifestyle changes.
• Stopping smoking — the single highest-yield change for a smoker, in both domains.
• Statins — some evidence suggests modest improvement in erectile function alongside their primary cardiovascular benefit.
• Blood pressure control — but the choice of agent matters. Older beta-blockers and thiazides are more often implicated in ED than ACE inhibitors, ARBs or calcium channel blockers. See medication side effects.
• Weight loss and glycaemic control — see obesity and diabetes.
