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 surgery, the patient is placed under general anesthesia. The surgeon makes an incision in the chest to access the heart and the affected arteries. CABG can improve heart function and reduce the risk of heart attacks, making it a common treatment for patients with severe coronary artery disease.
