Coronary artery bypass surgery (CABG), often referred to as heart bypass surgery, is a vital medical intervention aimed at restoring blood flow to the heart muscle in individuals with severely narrowed or blocked coronary arteries. This condition, known as atherosclerosis, restricts oxygen-rich blood from reaching the heart, leading to symptoms like chest pain (angina), shortness of breath, or even heart attacks.
CABG involves rerouting blood around the clogged arteries using healthy blood vessels from the patient's own body. This helps reduce symptoms and lowers the risk of future heart attacks. At our facility in Baner, experienced cardiac surgeons employ the latest techniques and equipment to ensure optimal outcomes.

Why is Coronary Bypass Surgery Needed After a Heart Attack?
A heart attack occurs when blood flow to part of the heart is suddenly blocked, often due to a clot forming over a ruptured plaque. After stabilisation, patients with significant blockages may be advised to undergo heart attack coronary artery bypass surgery to prevent further damage.
CABG is particularly recommended in:
-
Triple vessel disease (blockages in three main arteries).
-
Left main coronary artery disease.
-
Diabetic patients with diffuse disease.
-
Failed angioplasty or recurring blockages.
Your cardiologist will evaluate whether CABG is the most effective solution following a heart attack.
Understanding the CABG Procedure: Step-by-Step
What Happens During CABG Surgery?
This surgery is conducted under general anaesthesia. A midline chest incision is made, and the heart is accessed by opening the breastbone.
Types of Grafts Used in CABG
-
Saphenous Vein Graft (SVG): Taken from the leg.
-
Internal Mammary Artery (IMA): Taken from the chest.
-
Radial Artery: Taken from the arm.
On-Pump vs Off-Pump CABG Surgery
-
On-pump CABG: The heart is temporarily stopped, and a heart-lung machine is used.
-
Off-pump CABG: Performed while the heart is still beating using stabilisation techniques.
After grafting, the chest is closed, and the patient is moved to intensive care for monitoring.
Recovery After CABG Surgery: What to Expect
Post-surgery recovery includes:
-
Hospital stay: 5 to 7 days.
-
Pain management and wound care.
-
Medications: Blood thinners, beta-blockers, statins.
-
Cardiac rehabilitation: Supervised exercise and education.
-
Emotional health support.
-
Patients often return to light activity in 6–8 weeks and full recovery takes around 12 weeks. Our rehabilitation team supports you throughout this journey to ensure a safe and speedy recovery.
What Are the Risks of Coronary Artery Bypass Surgery?
Like any major surgery, CABG carries some risks. However, these are minimised by expert care and advanced surgical techniques.
|
Common Risks |
Rare Complications |
|
Bleeding |
Stroke |
|
Infection |
Kidney failure |
|
Irregular heartbeat |
Heart attack during surgery |
|
Reaction to anaesthesia |
Sternal wound complications |
Each patient undergoes a detailed preoperative evaluation to minimise complications.
Life Expectancy After Bypass Surgery: What the Research Says
CABG significantly improves survival in patients with advanced coronary artery disease. Studies show that many patients live 10–15 years or more after surgery, especially when combined with healthy lifestyle changes.
Key factors influencing life expectancy after bypass surgery:
-
Patient age and comorbidities.
-
Success of the procedure.
-
Lifestyle (smoking, diet, exercise).
-
Adherence to medications and regular follow-ups.
Patients under structured care and long-term monitoring see the best outcomes.
CABG vs Angioplasty: When is Surgery a Better Option?
|
CABG |
Angioplasty with Stenting |
|
Best for multiple blockages |
Best for isolated, short blockages |
|
Long-lasting outcomes |
May require repeat procedures |
|
Preferred for diabetics |
Less invasive but not always durable |
|
Suitable for left main artery disease |
Limited in complex cases |
CABG is often recommended for more complex cases, particularly in high-risk patients.
