A coronary artery bypass surgery, often referred to as coronary artery bypass grafting (CABG), is a surgical procedure used to treat coronary artery disease (CAD). During the procedure, new pathways are created around narrowed or blocked arteries in the heart by using a healthy blood vessel taken from another part of the body, typically the chest or leg. This redirects blood flow, avoiding the blocked section and improving blood supply to the heart muscle. CABG is performed to relieve chest pain, reduce the risk of heart attack, and improve overall heart function in patients with serious coronary artery disease that cannot be effectively managed through medications or lifestyle changes alone. It is a major surgery requiring careful evaluation before the procedure and thorough care afterward to ensure successful recovery and long-term benefits for the patient's heart health.
