Frequently Asked Questions
Who is the best cardiologist in Chennai?
The best cardiologist for you depends on your condition. Look for super-speciality cardiology training, interventional experience and a hospital with a 24×7 cath lab. Dr. S.

No. Many blockages are best treated with medicines and lifestyle changes. A stent or bypass is advised only when the blockage is significant, causing symptoms, or putting the heart muscle at risk.
