Coronary artery bypass grafting (CABG) is a surgical procedure used to improve blood flow to the heart. It involves taking a healthy blood vessel from another part of the body, such as the leg or chest, and using it to create a new pathway for blood to bypass blocked or narrowed coronary arteries. This helps to relieve symptoms of heart disease, such as chest pain and shortness of breath. During the CABG surgery, the heart may be temporarily stopped, and a heart-lung machine is used to maintain blood circulation. After the surgery, patients often experience improved heart function and a better quality of life, allowing them to return to their normal activities more easily.
