Blocked Heart Artery Overview

Another name for Blocked Heart Artery is Coronary Artery Disease.

What is coronary artery disease?
A person with coronary artery disease has narrowing of the arteries that supply blood and oxygen to the heart. Coronary artery disease is caused by atherosclerosis, which is also called hardening of the arteries. As the narrowing worsens, the arteries become unable to supply enough oxygen to meet demand. This can cause chest pain, known as angina. Severe narrowing increases the risk for blood clot formation inside one of the coronary arteries. When this occurs it is called a heart attack.

What are the symptoms of coronary artery disease?
Most people with coronary artery disease have no symptoms at all. When the narrowing worsens angina symptoms may develop. The most common symptoms of angina include chest pain or chest heaviness.

How does the doctor treat coronary artery disease?
Treatment for coronary artery disease includes no smoking, weight reduction, and a low fat and cholesterol heart diet. Some may benefit from medications to reduce chest pain and lower blood pressure. Some patients may be candidates for angioplasty or coronary artery bypass surgery.
