Atherosclerosis

What is atherosclerosis?

Atherosclerosis is sometimes called "hardening of the arteries." It occurs when fat (cholesterol) and calcium build up inside the lining of the artery wall. This forms a substance called plaque. Over time, the fat and calcium buildup may narrow the artery.

Atherosclerosis in the heart (coronary) arteries is called coronary artery disease. Atherosclerosis in the leg arteries is called peripheral arterial disease of the legs. If atherosclerosis affects the brain arteries (carotid or cerebral arteries), a stroke can occur.

If you have this buildup in one of your arteries, there's a good chance that you have it in other blood vessels throughout your body.

What are the symptoms of atherosclerosis?

Many people don't have any symptoms. If you have symptoms, they may depend on where the affected arteries are in your body. For example, symptoms can include chest pain or pressure (angina), leg pain or weakness, or belly pain. Sometimes the first symptom is a heart attack or stroke.

How is atherosclerosis diagnosed?

Your doctor will ask about your past health and will do a physical exam. You may have tests to see if your arteries are narrowed. Which tests you have depends on which arteries the doctor thinks are affected. Tests may include an electrocardiogram (EKG), an echocardiogram, heart stress tests, or a coronary angiogram.

How is atherosclerosis treated?
