Coronary artery bypass grafting (CABG) is the most commonly performed open heart operation. It is a surgical procedure in which one or more blocked coronary arteries are bypassed by a blood vessel graft to restore normal blood flow to the heart. CABG reduces chest pain and the risk of death from heart attack.

Isolated CABG means that only a CABG surgery is performed on the patient without any other procedure. In 2019, NHCS had performed 828 isolated CABG surgeries. The mortality rate in 2019 was 0.72%.
