Coronary Artery Disease (Overview)

The leading cause of death and disability in adults in the U.S. It develops when lipid (fatty) plaques builds up in the arteries, thereby stopping blood flow to the organ supplied by that artery. If the artery supplies the heart, blockage causes a heart attack. If the blockage is in a brain vessel, the result is a stroke.
