CABG aims to provide what main effect?

• A. To repair damage to the heart muscle
• B. To provide a new circuit for blood flow to get to the heart muscle
• C. To provide new vessels bringing blood to the right atrium
• D. To bypass obstructions in the ascending aorta

Answer: (B)

CABG is about reestablishing blood supply to heart muscle by creating a new route for blood to reach areas fed by narrowed or blocked coronary arteries. The grafts bypass the obstructions, supplying the myocardium with oxygen-rich blood and reducing ischemia. It doesn’t repair damaged muscle directly, it doesn’t create vessels specifically to the right atrium, and it doesn’t bypass the ascending aorta itself—the goal is to bypass coronary blockages to improve myocardial perfusion.
