Coronary Artery Bypass Grafting (CABG)

Coronary artery bypass grafting (CABG) is a procedure to improve poor blood flow to the heart. It may be needed when the arteries supplying blood to heart tissue, called coronary arteries, are narrowed or blocked. This surgery may lower the risk of serious complications for people who have obstructive coronary artery disease, a type of ischemic heart disease. CABG may also be used in an emergency, such as a severe heart attack.

CABG uses blood vessels from another part of the body and connects them to blood vessels above and below the narrowed artery, bypassing the narrowed or blocked coronary arteries. One or more blood vessels may be used, depending on the severity and number of blockages. The blood vessels are usually arteries from the arm or chest, or veins from the legs. Risks and possible complications may occur with this procedure. After CABG, your doctor may recommend medicines and heart-healthy lifestyle changes to further reduce your symptoms, treat your disease, and help prevent complications such as blood clots.
