What is CABG?

Coronary Artery Bypass Graft or CABG is a surgical procedure that is conducted on people with severe coronary artery disease to improve the blood flow in their cardiac blood vessels. This surgery is performed when the coronary arteries become narrowed or blocked due to the accumulation of plaque. CABG lowers the risk of the patient developing serious complications from coronary artery disease, such as a fatal heart attack.

During the procedure, blood vessels are removed from another part of your body and connected above and below the blocked area on the affected artery. This allows blood flow to bypass the blocked or narrowed coronary arteries. Depending on the number and severity of the blockages, a few blood vessels may be used. These are typically extracted from the arteries in your arms, legs or chest.

Who should undergo CABG?

People who suffer from obstructive coronary artery disease have the most to benefit from undergoing CABG. This disease is caused when your coronary arteries become narrowed or blocked, resulting in a lack of oxygen being supplied to the heart. Doctors recommend CABG if alternative treatments like medication or lifestyle changes have been unsuccessful. Emergency CABG is also performed on individuals who have suffered from a severe heart attack.

What are the results of a CABG?

After undergoing CABG, most people have reported healthier lives free of symptoms for many years. It is possible, however, that the same arteries or new ones may become clogged over time, requiring an angioplasty or another bypass. For long-term results, patients are advised to eat well-balanced, healthier diets, perform regular exercises and discontinue unhealthy habits like smoking.
