What is the goal of CABG surgery?

• A. To cure diabetes
• B. To improve the patient's quality of life
• C. To normalize blood pressure entirely
• D. To regenerate myocardium

Answer: (B)

CABG aims to restore blood flow to the heart muscle by bypassing narrowed or blocked coronary arteries with grafts. By revascularizing the myocardium, it relieves ischemia, reduces angina, and improves exercise tolerance, which together translate into a better overall quality of life for most patients. In certain patients with extensive disease, it can also improve survival, but the primary benefit seen by most individuals is symptom relief and improved daily functioning. It doesn’t cure diabetes, it doesn’t normalize blood pressure, and it doesn’t regenerate heart muscle; its main effect is to prevent further ischemia and lessen symptoms rather than restore new myocardium.
