Most people see a cardiologist for the first time in an ambulance. That is the wrong first appointment. This guide sets out the symptoms that need emergency care today, the ones that need an appointment this week, and the situations where you should see a cardiologist despite feeling completely well.

Call 108 immediately if you have any of these

Do not drive yourself. Do not wait to see whether it passes. Do not read the rest of this page.

Chest pain or heaviness lasting more than 15 minutes, especially with sweating, nausea or breathlessness
Pain spreading to the jaw, neck, left arm, both arms or between the shoulder blades
Sudden severe breathlessness, particularly if you cannot lie flat
Fainting or collapse, especially during exertion
Sudden tearing pain in the chest or back, described as ripping
Palpitations with dizziness, chest pain or near-fainting

Chewing a 300 mg aspirin while waiting for help is appropriate unless you are allergic or have been told not to.

Symptoms that are often dismissed — and should not be

Heart attacks do not always present as the crushing central chest pain of medical dramas. These presentations are missed regularly, by patients and sometimes by doctors:

In women

Women more often present without prominent chest pain. Unusual fatigue over days, breathlessness, nausea, indigestion-like discomfort, jaw or upper back pain, and a general sense of something being badly wrong are all recognised presentations. Women are more likely to be sent home from emergency departments with a non-cardiac diagnosis, and more likely to delay seeking help.

In people with diabetes

Diabetic neuropathy can blunt cardiac pain. A silent myocardial infarction may present only as sudden breathlessness, unexplained vomiting, confusion, a fall, or unusually poor glucose control. If you have had diabetes for many years and feel suddenly and inexplicably unwell, take it seriously.

Indigestion that is not indigestion

Burning upper abdominal discomfort brought on by walking and relieved by rest is not gastritis, whatever the antacid appears to do. Discomfort with a reliable relationship to exertion is cardiac until proven otherwise.

See a cardiologist within a week if you have

Chest discomfort on exertion that reliably settles with rest — this is the classic pattern of a significant narrowing, and it is a warning, not a reassurance
Breathlessness that is new or worsening at a level of activity you managed comfortably six months ago
Palpitations that are frequent, prolonged, or occur at rest
Ankle swelling that is new, especially with breathlessness lying flat or waking you at night
Dizziness on standing that is new, or any episode of near-fainting
A murmur newly found on examination
Blood pressure persistently above 140/90 despite treatment, or above 160/100 at any reading
Reduced exercise tolerance you have quietly attributed to age or weight

See a cardiologist even though you feel completely well

This is the part most people skip, and it is where the most life is saved.

If a close relative had early heart disease

A parent or sibling with a heart attack, bypass or stent before 55 in men or 65 in women substantially raises your own risk. You should be assessed roughly ten years before the age at which your relative was affected — not at the age they were affected.

If you are South Asian

South Asians develop coronary artery disease around a decade earlier than Western populations, at lower body weight, and frequently with cholesterol reports that look unremarkable on a standard panel. A normal lipid profile in an Indian patient is considerably less reassuring than the same result in a European one. Baseline assessment from age 35–40 is reasonable, earlier with a family history.

If you have diabetes, hypertension or chronic kidney disease

Each independently accelerates coronary disease. Diabetes in particular carries cardiovascular risk comparable to having already had a heart attack, which is why cardiac assessment is part of good diabetes care rather than an optional extra.

If you smoke, or stopped within the last five years

Risk falls after cessation but does not return to baseline immediately.

Before starting serious exercise after years of inactivity

Particularly if you are over 40, or over 35 with risk factors. The gym is a common place for a first cardiac event in a previously sedentary person.

What actually happens at the appointment

People avoid cardiology appointments partly because they imagine something more alarming than the reality. A first consultation is almost always:

A conversation — your symptoms, your family history, your habits. This is the most diagnostically valuable part and usually the shortest.
Examination — pulse, blood pressure in both arms, heart sounds, chest, ankles.
An ECG — painless, takes five minutes, stickers on your chest.
Blood tests — lipids, glucose or HbA1c, kidney function, and where appropriate Lp(a) and ApoB, which detect risk that a standard cholesterol panel misses.
Possibly an echocardiogram — an ultrasound of the heart. No radiation, no needles, takes twenty minutes.

Nothing in a first assessment is invasive. Angiography is only considered after these results indicate it, and it is a decision you take part in.

Questions worth asking your cardiologist

What is my actual risk over the next ten years, as a number?
Which of my risk factors can I change, and which cannot?
What does this test result mean in plain language?
If you are recommending a stent or bypass — what happens if I choose medication first?
Would any other cardiologist reasonably disagree with this plan?

That last question is a good one. A cardiologist confident in their recommendation will answer it without irritation. For any proposed bypass, stent, valve replacement or device implant, a second opinion is reasonable and standard practice.

The thing worth understanding

By the time an interventional cardiologist is threading a wire into someone’s coronary artery, the disease has usually been developing silently for twenty years or more. Almost every one of those years offered an opportunity to change the outcome — and almost none of them produced a symptom.

That is the case for going before something is wrong. Not because a check-up is pleasant, but because the window in which prevention works closes quietly, without warning you.

Frequently asked questions

At what age should an Indian adult have a first heart check-up?

Around 35–40 for most people, and earlier — from about 25–30 — if there is a family history of early heart disease, diabetes, hypertension or smoking. South Asians develop coronary disease roughly a decade earlier than Western populations, so guidance based on Western data starts too late.

Is chest pain always a heart attack?

No. Most chest pain is not cardiac. But chest discomfort that comes on with exertion and settles with rest, or that lasts more than 15 minutes with sweating, nausea or breathlessness, must be treated as cardiac until proven otherwise. The cost of investigating a non-cardiac pain is small; the cost of ignoring a cardiac one is not.

Can I have a normal ECG and still have heart disease?

Yes, and this is a common and dangerous misunderstanding. A resting ECG is often normal in significant coronary artery disease. It is a useful test, not a clearance certificate.

What is Lp(a) and why does it matter?

Lipoprotein(a) is a genetically determined particle that raises cardiovascular risk independently of LDL cholesterol. It is not measured on a standard lipid panel, it is largely unaffected by diet, and it is elevated in a meaningful proportion of South Asians — which is one reason people with apparently normal cholesterol still have heart attacks. It needs measuring once in a lifetime.

Do I need a cardiologist or is my physician enough?

For routine risk factor management, a good general physician is sufficient. See a cardiologist for symptoms suggesting angina or heart failure, an abnormal ECG or echo, an arrhythmia, a murmur, a strong family history of early heart disease, or before any decision about intervention.
