Heart Bypass Surgery

CABG Surgery in India - Who Is a Good Candidate?

Coronary artery bypass graft (CABG) surgery creates new routes for blood to flow around blocked arteries in the heart. This short explains who is generally considered a suitable candidate for this procedure.

The purpose of CABG surgery

CABG is a treatment for coronary artery disease, where the blood vessels supplying the heart muscle become narrowed or blocked.

• Relieving symptoms. It can reduce chest pain (angina) and shortness of breath, improving your ability to be active.
• Improving heart function. By restoring normal blood flow, the surgery can help the heart muscle work more effectively.
• Reducing risks. For certain patterns of artery blockage, CABG may lower the risk of a future heart attack.

Factors that determine suitability

A cardiac team will assess several factors to see if CABG is an appropriate option for you.

• Severity of disease. You may be a candidate if you have multiple blocked coronary arteries, especially the left main coronary artery.
• Response to other treatments. CABG is often considered if symptoms continue despite medication or less invasive procedures like angioplasty and stenting.
• Heart muscle health. The procedure is usually more effective if your heart's main pumping chamber, the left ventricle, is still functioning reasonably well.
• Overall health. Your general health must be good enough to undergo a major operation. Other medical conditions are taken into account.

When CABG may not be the first choice

• If you have only one or two blocked arteries, a stent procedure might be considered first.
• If the heart muscle is already severely damaged, the potential benefits of bypass surgery may be lower.
• For some patients with other serious health issues, the risks of surgery may outweigh the potential advantages.

The decision to proceed with CABG surgery is made on a case-by-case basis. A final recommendation depends on a cardiac surgeon's review of your specific medical history, test results, and recent heart imaging.
