CABG stands for **coronary artery bypass grafting**. It is a **surgical procedure** used to improve blood flow to heart muscle affected by coronary artery disease. CABG is commonly encountered in cardiology when evaluating **multivessel coronary disease**, **left main disease**, or symptoms not adequately controlled by other strategies.
