With how the heart functions within a human body, it can be compared to that of an engine which keeps your body running, and just like any engine, it needs an uninterrupted supply of oxygen-rich blood as fuel. When that blood supply is compromised due to blocked coronary arteries, a heart bypass surgery, also known as coronary artery bypass surgery or CABG surgery, can help restore proper blood flow. The surgery involves rerouting blood around blocked arteries by using blood vessels taken from another part of your body. This surgery helps in improving blood flow to the heart muscle, relieving symptoms like chest pain and reducing the risk of heart attacks.
Understanding the CABG procedure, the recovery timeline, lifestyle adjustments, and possible risks can help you make informed decisions and prepare better.
Synopsis
What is CABG Surgery and Why is it Needed?
CABG surgery is one of the most common forms of heart surgery. CABG is recommended when the coronary arteries that supply blood flow to your heart muscle are narrowed or blocked due to plaque. If lifestyle changes and medication alone are no longer enough, surgery may be the best option.
The concept behind the CABG procedure is simple and effective: if the main road is blocked, you build a new road. During the CABG surgery, surgeons take a healthy blood vessel from a leg (saphenous vein), arm (radial artery), or chest (internal mammary artery), and bypass it around the blocked artery so that blood can flow through the vessel grafted over the original blockage.
How the CABG Procedure Works
Usually, the surgery takes three to six hours under general anaesthesia. The surgery was performed as follows:
-
The surgeon made an incision in the chest in order to access the heart.
-
The heart was stopped temporarily and the synthetic heart-lung machine took over the circulation.
-
The surgeon took the donor vessel and positioned it above the blocked section, and below the blocked section.
-
Once the grafts were in place, the heart was allowed to restart. Finally the incision was closed.
Some patients may be eligible for off-pump CABG, where the heart will stay beating while performing the surgical intervention. The cardiac team will decide the most appropriate technique for you.
What to Expect After CABG Surgery
After surgery, you’ll require to spend a day or two in the intensive care unit (ICU), followed by few days in a regular hospital room.
Bypass surgery recovery continues at home and may take around 6–12 weeks. You may feel tired, sore, or emotional in the beginning. That’s completely normal, healing takes time. It’s essential to follow your doctor’s advice on activity levels, wound care, and medications during this period.
Physical therapy, breathing exercises, and gradual walking help rebuild strength. Many hospitals offer cardiac rehabilitation programs to guide you through recovery and lower your risk of future heart problems.
Diet After Heart Bypass Surgery
Nutrition plays a crucial role in healing. You should focus on a heart-healthy diet rich in:
|
Nutritional Focus |
Examples |
|
Fresh Fruits and Vegetables |
Apples, spinach, broccoli, berries |
|
Whole Grains |
Brown rice, quinoa, whole wheat bread |
|
Lean Proteins |
Fish, chicken, turkey |
|
Healthy Fats |
Nuts, olive oil, avocados |
Avoid foods high in saturated fats, salt, and added sugars. Hydration is equally important. If you have specific dietary restrictions or health concerns, consult a dietitian who can help you personalise your diet after heart bypass surgery.
Possible Complications of CABG Surgery
While CABG surgery is generally safe, like any major operation, it comes with some risks. These are usually well-managed in experienced centres like Manipal Hospitals, but being aware helps you stay alert.

Complications of CABG surgery may include:
-
Infection at the wound site
-
Bleeding or clot formation

Irregular heart rhythms (arrhythmias)
-
Memory issues or temporary confusion
-
Stroke or heart attack in rare cases
If you notice unusual fatigue, chest pain, fever, or swelling at the incision site after surgery, reach out to your doctor immediately.
Life After CABG Surgery
Life after CABG surgery can be rewarding if you’re committed to the recovery plan. Most people experience a significant improvement in their quality of life. You may be able to resume your normal activities, travel, or even get back to work within a few months, depending on your health.
What matters most is consistency:

FAQ's
Most people can return to daily activities within 6–12 weeks. Full recovery depends on your age, general health, and whether complications arise. Cardiac rehab can help speed up recovery.
Yes, medications to prevent clotting, manage cholesterol, and support heart function are often continued long-term.
Once your doctor gives the green light, usually after 6 to 8 weeks, you can travel. Always carry your medical records when you travel.
With proper care, grafts can last 10–15 years or more. However, the progression of heart disease depends on how well you manage your lifestyle post-surgery.
Yes, when necessary. Though more common in older adults, young patients with severe blockages or genetic predispositions may also need CABG surgery.
