What is the main goal of a coronary artery bypass graft?

The primary goal of a coronary artery bypass graft (CABG) is to improve blood flow to the heart muscle. This procedure is typically performed when one or more of the coronary arteries are narrowed or blocked due to coronary artery disease. By using a graft, which can be a vessel taken from another part of the body, the surgery creates a new pathway for blood to reach areas of the heart that may not be receiving sufficient oxygenated blood. Improved blood flow can alleviate symptoms such as angina (chest pain) and can also enhance overall cardiac function, reducing the risk of heart attack and other complications. Being able to restore adequate blood supply to the heart is vital for its health and function, which is why this goal is central to CABG procedures.
