Overview: Coronary artery disease (CAD)
Coronary artery disease (CAD, also called coronary heart disease, or CHD) is a condition in which the arteries that supply the heart with oxygen (called coronary arteries) have become narrower. The symptoms can vary greatly, depending on how narrow the arteries have become and how long it has been going on. It can lead to complications such as heart failure and heart rhythm problems. If a coronary artery suddenly becomes completely blocked, it can result in a heart attack.
