Erectile dysfunction can be an early warning sign of heart and artery disease. The European Association of Urology (EAU) 2025 guidelines describe it as a possible early sign of coronary and peripheral artery disease, and the Princeton IV consensus (2024) advises treating men with erectile dysfunction as at risk of cardiac events until proven otherwise. That is why erectile dysfunction deserves a medical assessment, not only tablets.

Why is erectile dysfunction linked to the heart?
Erections need good blood flow through the penile arteries, which are only about 1 to 2 mm wide. Diabetes, high blood pressure, high cholesterol, smoking and obesity damage artery linings throughout the body, so the effect may show in these small arteries before heart symptoms appear. Mayo Clinic notes that erectile dysfunction often comes 2 to 5 years before a heart attack.
What is erectile dysfunction associated with?
According to the EAU guidelines, erectile dysfunction is associated with higher risks of:
- Coronary heart disease.
- Stroke.
- Atrial fibrillation.
- Cardiovascular death and death from any cause.
What does the doctor check?
- Blood pressure, blood sugar, lipids and morning testosterone, as explained in erectile dysfunction tests.
- Your 10-year risk of heart disease.
- For some men at intermediate risk, a coronary artery calcium (CAC) scan to refine the risk.
- Referral to a cardiologist for men at high risk.
Is sex safe for heart patients?
Sexual activity is considered safe for most men who can walk about a mile (1.6 km) or climb two flights of stairs without symptoms. Men with a recent heart attack, heart failure or unstable angina need a cardiology assessment before starting erectile dysfunction treatment.
ED tablets and heart medicines
- Never combine ED tablets with nitrates (such as nitroglycerin or isosorbide) or riociguat.
- Tell your doctor about every medicine you take, especially blood pressure and prostate medicines.
What improves the heart and erections together?
Guidelines recommend lifestyle change and risk factor control before or alongside erectile dysfunction treatment: regular exercise, weight loss, stopping smoking, and controlling sugar, blood pressure and cholesterol. In one randomised trial, a diet and exercise programme resolved erectile dysfunction in about a third of men.

Frequently asked questions
Does erectile dysfunction mean I have heart disease?
Not necessarily. Erectile dysfunction has many causes, but it shares the same risk factors as heart disease, so your blood pressure, sugar and cholesterol deserve a check.
Are ED tablets dangerous for heart patients?
Many men with stable heart disease use them after a medical assessment, but they must never be combined with nitrates or riociguat because the combination can cause a dangerous drop in blood pressure.
When should I go to the emergency department?
If you have chest pain, severe breathlessness or severe dizziness during or after sex, call 998 and tell the medical team whether and when you took an ED tablet.
