How Bypass Surgery Helps Treat Severe Heart Disease

You’ve felt it more than once — a tightness in your chest, breathlessness after a short walk, or a discomfort that just doesn’t go away. If these signs feel familiar, the cause could be more serious than stress or ageing. For many Singaporeans, these symptoms point to severe coronary artery disease, one of the most common forms of heart disease. When lifestyle changes and medication aren’t enough, bypass surgery offers a well-established way to restore blood flow and relieve symptoms.

In this article, we’ll explain what bypass surgery involves, when it’s needed, how it works, what recovery looks like, and how much it costs in Singapore.

What Is Bypass Surgery?

Bypass surgery, or coronary artery bypass grafting (CABG), is a type of heart surgery that restores normal blood flow to the heart by creating new pathways around blocked arteries. These blockages happen when fatty deposits, or plaque, build up inside the coronary arteries, a condition known as coronary artery disease.

During the procedure, surgeons take healthy blood vessels from another part of your body, usually from your leg, chest, or arm, and use them to reroute blood around the clogged arteries. This allows oxygen-rich blood to reach your heart muscle again, which reduces the risk of heart attacks and relieves symptoms like chest pain or fatigue.

Doctors in Singapore usually recommend heart bypass surgery for patients with serious or complex heart problems. This includes people who:

• Have many blocked arteries or blockages that are hard to treat
• Can’t get angioplasty or stents because it’s too risky or wouldn’t work well
• Keep having chest pain (angina) even after taking medication
• Have had a heart attack or show signs that their heart isn’t pumping well
• Have diabetes and complicated heart disease, which makes other treatments less effective

In these situations, bypass surgery often gives better, longer-lasting results than stents or medication alone. It helps restore blood flow to the heart and reduces the chances of future heart attacks.

How the Procedure Works

Heart bypass surgery can be done through traditional open-chest methods or minimally invasive techniques, depending on your condition. The surgeon first removes a healthy vein or artery from another part of the body and then grafts it above and below the blocked portion of the coronary artery.

This new “bypass” allows blood to flow freely again. Most patients receive between two and four bypass grafts in a single operation. The surgery lasts between three and six hours. After the operation, you’ll usually stay in the hospital for four to seven days for close monitoring and recovery.

Key Benefits of Bypass Surgery

Heart bypass surgery provides life-changing benefits, especially for those with complex or advanced heart disease:

• Relieves angina and chest discomfort
• Improves exercise tolerance and energy levels
• Reduces the need for long-term medication
• Lowers the risk of future heart attacks
• Increases survival rates, especially for patients with diabetes or multiple blockages

Research consistently shows that patients with severe disease experience better long-term results from bypass surgery than from angioplasty alone.

Bypass Surgery Cost in Singapore

In Singapore, the cost of bypass surgery can vary depending on the hospital type and whether you are a subsidised patient.

Here’s an overview:

• Public hospitals (subsidised):
  From S$8,000 to S$35,000, depending on ward class, surgery complexity, and length of stay
• Private hospitals:
  Ranges from S$25,000 to S$80,000, depending on the hospital, surgeon’s fees, and care package

What to Expect During Recovery

After bypass surgery, most patients recover in the Intensive Care Unit (ICU) for a day before moving to a standard ward. By the third or fourth day, you’ll begin walking short distances, breathing exercises, and light activities.

Full recovery takes about six to twelve weeks, depending on your age, overall health, and how many grafts were placed.

Cardiac rehabilitation programmes are strongly encouraged. These include:

• Supervised physiotherapy
• Nutrition counselling
• Stress management and lifestyle changes
• Regular heart check-ups

Most patients return to work and everyday activities within two to three months, often feeling more energetic and less limited by symptoms.
