Coronary angioplasty

Coronary angioplasty (AN-jee-oh-plas-tee) is a medical procedure in which a balloon is used to open a blockage in a coronary (heart) artery narrowed by atherosclerosis (ATH-er-o-skler-O-sis). This procedure improves blood flow to the heart.

Atherosclerosis is a condition in which a material called plaque (plak) builds up on the inner walls of the arteries. This can happen in any artery, including the coronary arteries. The coronary arteries carry oxygen-rich blood to your heart. When atherosclerosis affects the coronary arteries, the condition is called coronary artery disease (CAD).

Angioplasty is a common medical procedure. It may be used to:

* Improve symptoms of CAD, such as angina and shortness of breath.
* Reduce damage to the heart muscle from a heart attack. A heart attack occurs when blood flow through a coronary artery is completely blocked. Angioplasty is used during a heart attack to open the blockage and restore blood flow through the artery.
* Reduce the risk of death in some patients.
