A small artery can tell a big story
The penile arteries are smaller than many arteries supplying the heart. Problems with blood-vessel function may affect erections before a man notices heart symptoms. ED is a marker of increased cardiovascular risk, not proof that a heart attack is coming.
Know your risk factors
High blood pressure, diabetes, cholesterol problems, smoking, physical inactivity, obesity, and family history all matter. Your clinician may check blood pressure, glucose, lipids, and overall cardiovascular risk.
What can improve the picture
Regular exercise, healthier eating, weight management when appropriate, stopping tobacco, limiting heavy drinking, and treating diabetes or blood pressure can protect both your heart and sexual health. Changes may help erections, but results vary.
When safety comes first
If you have chest pain, fainting, or severe breathing difficulty, seek emergency care. Men with unstable cardiac symptoms should receive medical advice before sexual activity or ED medication. Sildenafil and tadalafil must never be combined with nitrates or riociguat.
The point
Do not treat ED like an isolated plumbing complaint. Check the building, too.
