Coronary Artery Bypass Graft Surgery (CABG)
Coronary Artery Bypass Graft Surgery (CABG) Coronary artery bypass graft surgery – most commonly referred to as "bypass surgery" and sometimes called CABG (pronounced "cabbage") – is a common heart surgery that reroutes, or bypasses, blood around clogged arteries to improve blood flow and oxygen to the heart. Blocked arteries can slow or stop blood flow through the heart's blood vessels, leading to chest pain or a heart attack. Increasing blood flow to the heart muscle can relieve chest pain and reduce the risk of heart attack.
