Coronary Artery Disease



Coronary artery disease (CAD), also called coronary heart disease, is a condition in which plaque (plak) builds up inside the coronary arteries. These arteries supply your heart muscle with oxygen-rich blood.
 
Plaque narrows the arteries and reduces blood flow to your heart muscle. It also makes it more likely that blood clots will form in your arteries. Blood clots can partially or completely block blood flow.
 
Plaque is made up of fat, cholesterol, calcium and other substances found in the blood. When plaque builds up in the arteries, the arteries harden.

 

CAD is the most common type of heart disease.

It's the leading cause of death in the United States for both men and women. Lifestyle changes, medicines, and/or medical procedures can effectively prevent or treat CAD in most people.
