Tamil Nadu's 7 largest listed cities add up to roughly 22.5 million people. Chennai (12.3 million), Coimbatore (3.2 million) and Madurai (1.9 million) lead the list, with 4 other cities behind them. Most figures are 2025 estimates and should be read as approximate.
Applying state-level hospital-bed ratios to these populations gives about 43,000 hospital beds, including some 2,100 ICU beds, in an estimated 680 hospitals (roughly 340 public and 340 private). Tamil Nadu averages 1.91 beds per 1,000 people against about 1.39 for India, and about 50% of its beds are private.
On the national ratio of one practising doctor per 811 people, these cities would have about 28,000 doctors and 50,000 nurses and midwives across all systems of medicine. A cardiologist is one of many specialities within that total. Specialist head-counts are not published city by city, so these figures show scale, not how many cardiologists practise in Tamil Nadu.
Tamil Nadu has infant mortality of 11 per 1,000 live births (India: 24) and modelled life expectancy of about 75.0 years (India: about 72). This page lists 7 cardiologists across these cities, and every city and sister city below has its own page with maps, qualifications to check and answers to common questions.

How to choose a cardiologist
- Check the qualification: MBBS, MD (Medicine) and DM or DNB (Cardiology).
- Verify registration with the NMC / State Medical Council register (look for a DM or DNB in Cardiology) and note the registration number.
- Ask how long the clinic has treated the condition you have, not just how long the doctor has practised.
- Read recent patient feedback on more than one platform, and be wary of identical glowing reviews.
- Check practical details: location, clinic hours, appointment system, and whether emergency back-up exists if something goes wrong.
A cardiologist (physician) is different from a cardiac surgeon (MCh CTVS). Surgeons operate on the heart; cardiologists diagnose, treat with medicines and perform procedures such as angioplasty.

How many cardiologists are listed in Tamil Nadu?

Who is the best cardiologist in Tamil Nadu?
There is no single best doctor for everyone: the right choice depends on your condition, budget and city. Shortlist two or three cardiologists, check their qualification and registration with the NMC / State Medical Council register (look for a DM or DNB in Cardiology), and compare facilities and communication. Apollo Hospitals Chennai (Chennai) is the first listing on this page - confirm details by phone.
When should I see a cardiologist rather than a general physician in Tamil Nadu?
See a cardiologist for chest discomfort on exertion, palpitations, unexplained breathlessness, fainting, or if you have had a heart attack or stent. A general physician can do the first check and refer you, but a cardiologist can interpret echo, TMT and angiography results.
Which heart tests are usually done first?
An ECG is quick and widely available. Based on your history the cardiologist may add an echocardiogram to look at heart function, a treadmill test to see how the heart behaves under stress, and blood tests such as a lipid profile. Angiography is reserved for cases where blockages are suspected.
