Conditions
Triple vessel coronary artery disease
Quick answer
Triple vessel disease means all three main heart arteries have significant blockages. It often causes chest pain or breathlessness and raises heart attack risk. Bypass surgery (CABG) is commonly recommended, especially with diabetes or a weak heart. In some cases multi-vessel angioplasty is an alternative.

What this stage or type means
- Significant narrowing in the left anterior descending, circumflex and right coronary arteries.
- Seen on coronary angiography or CT angiography.
- A SYNTAX score grades how complex the blockages are.
- Diabetes and reduced pump function make bypass more favoured.
- A heart team of surgeon and cardiologist ideally reviews the case together.
Treatment options
CABG
Bypass grafts using chest wall arteries and leg or arm vessels route blood past all three blockages.
Beating-heart or minimally invasive CABG
Selected patients may have bypass without the heart-lung machine or through smaller cuts.
Multi-vessel angioplasty
Stents may be chosen when blockages are simpler (low SYNTAX score) or surgery risk is high.
Medical therapy
Medicines are always part of care, before and after any procedure.
Tests that confirm it
- Coronary angiography
- SYNTAX score calculation
- Echocardiogram
- Stress test or FFR for borderline lesions
- Carotid Doppler and lung tests before surgery
Outlook
Treating triple vessel disease relieves symptoms and, in suitable patients, may lower heart attack risk. The choice between bypass and stents depends on blockage pattern, diabetes and heart function.
Planning treatment in India
- Bypass surgery means a hospital stay followed by recovery near the hospital; your surgeon will set the date you can fly.
- Send the angiography CD (video) and report, echo and blood tests first; teams decide from the video.
- Stop or adjust blood thinners only on your cardiologist's advice before surgery.
- Arrange a cardiologist and cardiac rehabilitation at home for the months after surgery.
Questions to ask your specialist
- What is my SYNTAX score?
- Is bypass or angioplasty better for my anatomy?
- Will you use arterial grafts?
- Is beating-heart surgery an option for me?
- How long before I can fly home?

Frequently asked questions
Why is bypass often preferred for three blocked arteries?
For complex blockages, especially with diabetes, bypass often gives more complete and durable blood supply than stents.
Can I have stents instead?
Sometimes, if blockages are short and simple. A heart team reviews your angiogram.
How long do bypass grafts last?
Artery grafts tend to stay open longer than vein grafts. Lifestyle and medicines help protect them.
