Cardiologists in Delhi at a glance
Quick facts about Delhi and its healthcare system. Hospital, bed and doctor figures are estimates scaled from state and national data, because no public source counts them city by city.

Delhi has an estimated 34.7 million (347 lakh) residents in 2025, based on the UN's 2024 World Population Prospects urban-area estimate. That makes it number 1 among the 100 largest cities in this directory, and falls in our Metro (5M+) size band. At the assumed growth of 2.5% a year, it would reach about 39.3 million by 2030, so demand for cardiologists and every other speciality is likely to keep rising.
Scaling Delhi's 2.08 beds per 1,000 people (the India-wide figure is about 1.39) to the city's population gives roughly 72,000 hospital beds in Delhi, including about 3,600 ICU beds, spread across an estimated 320 hospitals (about 200 public and 120 private). That is about 481 residents for every bed and around 220 beds per hospital on average. Measured against the WHO's often-quoted benchmark of 3 beds per 1,000 people, the city would need roughly 32,000 more beds, which is one reason private clinics and hospitals carry so much of the load.
The same national ratio of one practising doctor per 811 people suggests about 43,000 practising doctors across all systems of medicine in Delhi, supported by around 77,000 nurses and midwives. 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 Delhi.
On health outcomes, Delhi's infant mortality rate is 11 per 1,000 live births (2024), well below the national figure of 24, and modelled life expectancy is about 73.8 years against roughly 72 for India; these are state-wide measures, not city measurements. About 38% of hospital beds in Delhi are private, so most people weigh private cardiologists against government outpatient departments. This page lists 1 cardiologist for Delhi.
General information compiled from public sources (MoHFW, SRS 2024, CDDEP / One Health Trust, UN WPP 2024, Census 2011); estimates, not official counts, and not medical advice. Listings marked "Online Verified" come from public online sources: please confirm details with the provider.
What cardiologists in Delhi treat
People in Delhi usually consult a cardiologist for the conditions below. Services differ between clinics and hospitals, so confirm what is available.
Common conditions and services
- Chest pain evaluation
- Heart failure
- Irregular heartbeat (arrhythmia)
- Coronary artery disease
- Post-heart-attack follow-up
- Preventive heart screening
Tests and checks you may be asked for

Also searched as: heart doctor, heart specialist, angioplasty doctor, cardiac care.
When to see a cardiologist in Delhi
- Chest discomfort on exertion
- A family history of early heart disease
- Diabetes, high blood pressure or high cholesterol
- Swelling of the feet with tiredness
- Follow-up after a heart attack, stent or bypass
Emergency: Sudden chest pain spreading to the arm or jaw, sweating or collapse may be a heart attack: call 108 immediately and do not drive yourself. India's free ambulance number is 108.
How to choose a cardiologist in Delhi
- 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.
Healthcare in Delhi: the bigger picture
Using state-level data scaled to its population, Delhi is estimated to have about 72,000 hospital beds across roughly 320 hospitals, including around 3,600 ICU beds. Delhi state averages about 2.1 hospital beds per 1,000 people, above the India-wide figure of roughly 1.4. About 38% of beds in Delhi are in the private sector, so many patients choose between private clinics and government hospitals depending on cost and the kind of care needed.
Major hospitals and teaching institutions often associated with Delhi include AIIMS Delhi, Safdarjung, RML, LHMC and Maulana Azad MC. Availability of Cardiologist services varies by department and by day, so check outpatient timings directly before visiting. (This list is general knowledge, not a complete or verified directory, and includes both public and private institutions.)
For context on health outcomes in Delhi: the state infant mortality rate is 11 per 1,000 live births (2024), lower than the national figure of 24, and modelled life expectancy is about 73.8 years, above the national estimate of 72. These are state-wide figures, not city measurements.
Across all systems of medicine, Delhi is estimated to have around 43,000 practising doctors at the national ratio of one per 811 people. Specialist numbers are not published by city, so a cardiologist's qualification and registration are the best things to verify.
Data note: UN figure is the NCR agglomeration but the state ratios use Delhi-state population, so city estimates run high.
Before you visit: what to carry
- Bring earlier ECGs, echo and angiography reports
- Note when the discomfort occurs and how long it lasts
- Wear comfortable clothes if a treadmill test is planned
Frequently asked questions: Cardiologists in Delhi
Who is the best cardiologist in Delhi?
There is no single best doctor for everyone: the right choice depends on your condition, budget and location. A good approach is to 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. On this page, Fortis Escorts Okhla (Metro Station, Okhla Rd, opposite Sukhdev Vihar, New Friends Colony, New Delhi, Delhi 110025) is one listed option - confirm details by phone before you visit.
How can I book an appointment with a cardiologist in Delhi?
Call the clinic or hospital number shown on the listing, use WhatsApp where it is shown, or visit during outpatient hours. Ask about the consultation fee, whether an appointment is needed, and which documents or earlier reports to bring.
How much does a cardiologist consultation cost in Delhi?
Fees depend on the doctor's experience, the type of facility and the tests or procedures involved, and we do not publish unverified prices. Ask the clinic for the consultation fee and any follow-up charges when you call; government hospitals generally charge much less than private clinics.
Which hospitals in Delhi offer cardiologist services?
Well-known hospitals and institutions often named for Delhi include AIIMS Delhi, Safdarjung, RML, LHMC and Maulana Azad MC, and the city also has many other hospitals and clinics. Each has its own outpatient timings and departments, so check availability for cardiologist services directly before you go. This is general information, not a complete directory.
When should I see a cardiologist rather than a general physician in Delhi?
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.
What is the difference between a cardiologist and a cardiac surgeon?
A cardiologist treats heart disease with medicines and catheter-based procedures like angioplasty. A cardiac surgeon (MCh CTVS) performs open or minimally invasive surgery such as bypass or valve replacement. They often work together on the same patient.
Can I get a heart check-up in Delhi without symptoms?
Yes. Preventive check-ups usually include blood pressure, ECG, lipid profile and sugar tests, and are worth considering after 40, or earlier with diabetes, smoking, obesity or a family history of heart disease.
How many hospital beds does Delhi have?
No public source counts beds city by city. Scaling state data to the city population gives an estimate of about 72,000 beds (around 3,600 ICU beds) for Delhi. Treat it as a rough guide rather than an official count.
