Symptoms
By Mayo Clinic staffAtherosclerosis develops gradually. Mild atherosclerosis usually doesn't have any symptoms.
You usually won't have atherosclerosis symptoms until an artery is so narrowed or clogged that it can't supply adequate blood to your organs and tissues. Sometimes a blood clot completely blocks blood flow, or even breaks apart and can trigger a heart attack or stroke.
Symptoms of moderate to severe atherosclerosis depend on which arteries are affected. For example:
- If you have atherosclerosis in your heart arteries, you may have symptoms similar to those of a heart attack, such as chest pain (angina).
- If you have atherosclerosis in the arteries leading to your brain, you may have signs and symptoms such as sudden numbness or weakness in your arms or legs, difficulty speaking or slurred speech, or drooping muscles in your face. These are signs of a transient ischemic attack (TIA) — which, if left untreated — may progress to a stroke.
- If you have atherosclerosis in the arteries in your arms and legs, you may have symptoms of peripheral artery disease, such as leg pain when walking (intermittent claudication).
Sometimes atherosclerosis causes erectile dysfunction in men.
When to see a doctor
If you think you have atherosclerosis — or risk factors for hardening of the arteries — talk to your doctor. Also pay attention to early symptoms of inadequate blood flow, such as chest pain (angina), leg pain or numbness. Early diagnosis and treatment can stop atherosclerosis from worsening and prevent a medical emergency.
