Coronary artery bypass graft (CABG) surgery treats blocked or narrowed coronary arteries by creating new routes for blood to reach the heart muscle. Surgeons use a healthy blood vessel from another part of the body to bypass the blocked artery, restoring normal blood flow and reducing the risk of heart attack. CABG remains one of the most effective treatments for severe coronary artery disease, with decades of proven outcomes worldwide.
Bypass surgery is typically recommended when coronary angiography shows significant blockages in multiple arteries, when medication and lifestyle changes are no longer enough to control symptoms, or when the left main coronary artery is significantly narrowed. Your cardiologist will confirm the need for surgery based on angiography results, the number and location of blockages, and your overall heart function.
