Coronary Artery Disease (CAD) Overview
Coronary artery disease (sometimes referred to as CAD) is a common and serious condition that occurs when the arteries supplying blood to the heart become narrowed or blocked due to the buildup of plaque in the arteries. When this mixture of fat, cholesterol and other substances affects the arteries, it is known as atherosclerosis. Atherosclerosis restricts blood flow and reduces oxygen to the heart, which can lead to symptoms like chest pain (angina) and, in severe cases, heart attacks.
