Coronary Artery Bypass Grafting (CABG)

Coronary Artery Bypass Grafting (CABG) - Causes and Risk Factors


Heart attack’ is the second commonest cause of death after cancer in Singapore. It is also the third commonest reason for patients to be admitted into hospital. CABG surgery performed for this condition, is the most common open heart operation.

Heart attack occurs when the coronary arteries supplying blood to the heart becomes hardened and subsequently blocks (coronary artery disease). Coronary artery bypass grafting is an established operation to restore the blood supply to the heart.


The risk factors for heart disease include diabetes, high blood pressure, excessive blood cholesterol, obesity and smoking. Although increasing age and male gender increases the risks as well, these are ‘non-modifiable’ risks. A strong family history of coronary artery disease however (especially first degree relatives younger than 50 years old) should prompt early consultation when symptoms arise.

CABG results are more durable as they last an average of 10 years. However, it has a slightly higher risk for complications than coronary angioplasty (also known as percutaneous coronary intervention, or PCI). It also requires a longer hospital stay (one week) and longer recovery (one to two months).
