Coronary Artery Bypass Graft (CABG)
Coronary artery bypass graft (CABG) is done to improve blood flow to the heart, creating a passage around blockages in the heart arteries. When blockages occur in the heart blood vessels, the heart is unable to get enough blood and oxygen. The blockages cause chest pain (angina) or a heart attack. The doctor is able to improve blood flow by attaching a piece of blood vessel (either a vein or an artery) above and below the blockage. The piece of blood vessel (graft) comes from one of these: leg, wrist, chest or stomach. Blood to the heart is improved when the blood can flow around the blocked areas through the new blood vessel.
