What is the procedure known as CABG?

CABG, or Coronary Artery Bypass Grafting, is a surgical procedure performed to improve blood flow to the heart by bypassing blocked or narrowed coronary arteries. The surgery involves using a blood vessel from another part of the body (like the leg, arm, or chest) and grafting it to the coronary artery, allowing blood to flow around the blockage. This procedure is particularly important for patients with severe coronary artery disease, as it can significantly reduce the risk of heart attacks and improve overall heart function.

Understanding this procedure is crucial, as it highlights the importance of surgical interventions in treating heart disease, which is a leading cause of morbidity and mortality worldwide. The other options pertain to different surgical procedures: emergency surgery can encompass a wide range of situations, gallbladder removal (cholecystectomy) specifically addresses gallbladder-related issues, and hernia repair focuses on strengthening areas of weakness in the abdominal wall. None of these options relate to the bypassing of coronary arteries or enhancing cardiac blood flow, which is the primary purpose of CABG.
