CABG refers to which surgical procedure?

• A. Percutaneous transluminal coronary angioplasty
• B. Metabolic equivalent table
• C. Coronary artery bypass graft
• D. Angina

Answer: (C)

CABG stands for coronary artery bypass graft, a surgical procedure that creates a new route for blood to reach the heart muscle by using a graft vessel to bypass blocked coronary arteries. Grafts are commonly taken from the internal mammary artery or the saphenous vein. This is different from a catheter-based procedure that dilates a blockage without a bypass graft, a term used for angioplasty; a metabolic equivalent table is a measure of exercise capacity, not a surgery; and angina is chest pain due to ischemia, not a procedure.
