Diseases & Conditions: Coronary Artery Disease

In coronary artery disease, atherosclerosis occurs in the main blood vessels to the heart, the coronary arteries. A buildup of cholesterol plaque narrows the arteries, and less blood reaches the heart. This is especially likely during moments of physical stress, leading to angina. Narrowed arteries also have the potential to become plugged with a blood clot. When the blood flow to the heart is blocked, a heart attack occurs and the heart muscle can become damaged.
