A heart attack - known medically as a myocardial infarction - happens when the blood flow to a part of the heart muscle is blocked, usually by a clot forming on a cholesterol plaque inside a coronary artery. Recognising the symptoms early and getting medical help quickly is one of the most important things you can do for yourself or a loved one. This guide explains exactly what to look for, what to do, and what happens next.

What is a Heart Attack?

A heart attack occurs when blood flow to a part of the heart muscle is suddenly reduced or completely blocked. Without oxygen-rich blood, that part of the heart muscle can begin to die within minutes. The longer treatment is delayed, the greater the risk of permanent heart damage.

How a Heart Attack Damages the Heart Muscle

The most common cause is coronary artery disease - a slow build-up of cholesterol, fat, and other substances (plaque) inside the arteries that supply the heart. When a plaque ruptures, the body forms a clot at the site, which can suddenly block the artery. The heart muscle downstream is starved of oxygen and cells begin to die. Less commonly, a heart attack can be caused by a severe spasm of a coronary artery, a spontaneous tear in the artery wall (SCAD - most common in younger women) or stimulant drugs such as cocaine.

Types of Heart Attack: STEMI, NSTEMI, and Unstable Angina

• STEMI (ST-Elevation Myocardial Infarction): the most serious type. A coronary artery is completely blocked, showing characteristic changes on the ECG. STEMI needs the artery reopened as fast as possible - usually within 90 minutes - through primary angioplasty (PCI) or, if not available, clot-busting medicine.
• NSTEMI (Non-ST-Elevation Myocardial Infarction): the artery is partially blocked or briefly blocked and then reopens. Heart muscle damage occurs (troponin levels rises in the blood) but ECG changes are subtler. It is still a genuine heart attack and a medical emergency.
• Unstable angina: chest pain that is new, occurs at rest, or has become more frequent or severe. The artery is narrowed but not damaging the heart muscle yet (troponin is normal). It is a warning sign that a full heart attack may occur soon and requires urgent medical evaluation.

Heart Attack vs Cardiac Arrest: A Critical Distinction

These two terms are often confused, but they are different problems with different responses:

• Heart attack is a circulation problem - a blocked artery causing heart muscle damage. The person is usually conscious and can describe symptoms.
• Cardiac arrest is an electrical problem - the heart's rhythm suddenly fails, the heart stops pumping, and the person collapses, becomes unresponsive, and stops breathing normally. Without CPR and defibrillation, death follows within minutes.

A heart attack can trigger a cardiac arrest. That is why every minute lost matters, and why anyone witnessing a collapse should call for help and start CPR immediately.

How Common Are Heart Attacks in India?

Cardiovascular disease is the leading cause of death in India, responsible for around 28% of all deaths in 2016 — up from 15% in 1990. India also has the highest burden of ST-elevation myocardial infarction in the world. Of greatest concern is how early heart attacks now strike in Indians: the Indian Heart Association reports that about half of all heart attacks in Indian men occur under age 50, and a quarter occur under age 40. Heart attacks tend to occur about a decade earlier in Indians than in Western populations, driven by a combination of genetic predisposition, abdominal obesity, diabetes, dyslipidaemia, smoking, and lifestyle stress.

Top 10 Symptoms of Heart Attack

Heart attacks can begin suddenly and intensely, or build slowly over hours. Most people experience one or more of the following:

1. Chest pain or discomfort: The most common symptom. Often described as pressure, squeezing, fullness, heaviness, or a "band tightening" sensation in the centre or left side of the chest. It typically lasts more than a few minutes, or comes and goes.
2. Pain radiating to other parts of the upper body: Discomfort may spread from the chest to one or both arms, the back, neck, jaw, teeth, or upper stomach. Left-arm pain is classic but pain in the right arm or both arms is common too.
3. Shortness of breath: Difficulty catching breath, often described as "I just couldn't get enough air". This can happen with or without chest pain, and is especially common in women, the elderly, and people with diabetes.
4. Cold sweat: Sudden, profuse, clammy sweating without a clear reason - even at rest in a cool room.
5. Nausea or vomiting: May feel like an upset stomach or food poisoning. More common in women than men.
6. Unusual fatigue: A heavy, drained tiredness that is out of proportion to recent activity. May begin days or weeks before the heart attack itself.
7. Lightheadedness or sudden dizziness: Feeling faint, unsteady, or as though you might pass out, often due to a drop in blood pressure or arrhythmia.
8. Irregular or rapid heartbeat (palpitations): A pounding, fluttering, or skipping sensation in the chest.
9. Anxiety or sense of impending doom: A strong, hard-to-explain feeling that something terrible is about to happen. Patients who survive often describe this distinctly.
10. Heartburn or indigestion-like discomfort: A burning sensation that can be mistaken for acid reflux. If it does not settle quickly, or comes with any other symptom on this list, treat it as cardiac until proven otherwise.

Early Warning Signs of a Heart Attack (Days to Weeks Before a Heart Attack)

Many people - especially women - recall warning signs in the days or weeks leading up to a heart attack. These are often dismissed as flu, stress, or aging. Pay attention to:

• New or worsening chest discomfort, especially on exertion (early-onset angina).
• Severe, unexplained fatigue that does not improve with rest.
• Breathlessness on minor exertion - walking up stairs, light housework - that is new for you.
• Sleep disturbance: difficulty falling asleep, waking unrested, or new-onset insomnia.
• Persistent indigestion, nausea or vague abdominal discomfort.
• Mild palpitations or new awareness of an uneven heartbeat.
• A general sense of being unwell or "not right", without an obvious explanation.

If you have any of these, particularly with risk factors such as diabetes, high blood pressure, smoking, or family history, see a cardiologist promptly - do not wait for chest pain.

Heart Attack Symptoms in Women vs Men

Why the Difference Matters

Cardiovascular disease is the leading cause of death in women globally, yet symptoms in women are more often atypical, dismissed, or misattributed to anxiety, indigestion, or the flu). Recognising the difference is life-saving.

Classic Symptoms in Men

Men are more likely to present with the textbook picture: central chest pressure, left-arm pain, sweating, and shortness of breath, often during physical exertion or emotional stress.

Atypical Symptoms in Women

Women may have a heart attack with no chest pain at all. Common presentations include unusual fatigue, breathlessness, indigestion, upper-back pressure, jaw or neck ache, dizziness, and a vague sense of unwellness. These symptoms can build over days. If something feels wrong - particularly with diabetes, hypertension, family history, or after menopause - do not assume it is anxiety or indigestion. Have it checked.

Heart Attack Symptoms in Special Populations

Symptoms in People with Diabetes

Diabetes damages the small nerves that carry pain signals (autonomic neuropathy). As a result, people with long-standing diabetes often have heart attacks with mild, vague, or no chest pain at all - sometimes only breathlessness, sweating, or sudden weakness. Silent heart attacks are more common in this group. If you have diabetes, treat any new breathlessness, fatigue or upper-body discomfort seriously.

Symptoms in the Elderly

Older adults (especially those over 75) may present with confusion, sudden weakness, falls, or simply not feeling themselves, rather than classic chest pain. Breathlessness is often the dominant complaint. A low threshold for seeking emergency care is essential.

Symptoms in Children and Young Adults

Heart attacks in children are rare but not impossible - they can occur in those with congenital coronary anomalies, Kawasaki disease sequelae, or familial hypercholesterolaemia. Young adults with strong family history, recreational drug use, or known hyperlipidaemia can also have heart attacks. Symptoms in young people may be atypical: palpitations, fainting, sudden chest tightness on exertion. Any unexplained collapse, persistent chest pain, or breathlessness in a young person warrants urgent assessment.

Silent Heart Attack: Symptoms and Risks

A silent heart attack is one with no obvious symptoms - or symptoms so mild they are mistaken for indigestion, fatigue, or a flu-like illness. The heart muscle damage still happens, and the patient is often diagnosed only weeks or months later on a routine ECG. About 1 in 5 heart attacks in the United States are silent. Common features include vague chest discomfort, brief breathlessness, mild jaw or back ache, persistent tiredness and a flu-like feeling. Silent heart attacks are more common in people with diabetes, the elderly, and women. The long-term risk of heart failure or a second heart attack is higher because the damage was never treated.

Mini Heart Attack: Unstable Angina and Small NSTEMI

The phrase "mini heart attack" is used loosely to refer to two distinct medical conditions:

• Unstable angina: chest pain at rest or on minimal exertion, due to a narrowed but not blocked coronary artery. Troponin (the blood marker of heart damage) is normal, but the risk of a full heart attack in the days that follow is high.
• A small NSTEMI: a small heart attack where only a limited area of muscle is damaged, with a modest troponin rise but without ST-elevation on the ECG.

Both are medical emergencies. Both need urgent admission, cardiac monitoring and usually coronary angiography to plan further treatment. Do not assume "mini" means "minor".

Heart Attack vs Other Causes of Chest Pain

Heart Attack vs Heartburn or Indigestion

Heartburn typically feels like a burning sensation behind the breastbone, often after a meal or when lying down, and usually settles with an antacid. Heart attack pain is more often pressure, tightness or squeezing across a broader area, may radiate to the arm or jaw, and is commonly accompanied by sweating, nausea or breathlessness. If you cannot tell, treat it as a heart attack until evaluated.

Heart Attack vs Panic Attack

Panic attacks and heart attacks share many overlapping symptoms - chest tightness, palpitations, breathlessness, sweating, lightheadedness and a sense of impending doom. The differences are not always reliable, but as a guide:

• Panic attacks usually peak within 10 minutes, and the chest discomfort tends to be sharp, localised or pinpoint rather than pressure-like.
• Heart-attack pain is more often a heavy pressure or squeezing, may radiate to the arm or jaw and tends to last longer or come and go.
• Panic symptoms often follow an emotional trigger; heart attack pain can occur at rest or wake you from sleep.
• When in doubt, especially in an older adult or anyone with risk factors, treat it as a heart attack and seek emergency care.

Heart Attack vs Muscle or Costochondritis Pain

Pain from a strained chest-wall muscle or inflammation of the cartilage between the ribs (costochondritis) is usually sharp, worse with movement or pressing on the spot, and reproducible by touch. Heart attack pain is rarely worsened by pressing, is more diffuse, and is not relieved by changing position. Still, if uncertain, get checked.

Risk Factors for Heart Attack

Non-Modifiable Risk Factors

• Age: risk rises significantly after 45 in men and 55 in women, but heart attacks in younger Indians are increasingly common.
• Sex: men have a higher risk at any age, but women catch up after menopause.
• Family history: a parent, sibling, or grandparent with heart disease before 55 (men) or 65 (women) doubles your risk.
• Ethnicity: South Asians have a higher genetic risk and tend to have heart attacks about a decade earlier than Europeans.
• Previous heart attack, stroke or peripheral arterial disease: the strongest single predictor of a future event.

Modifiable Risk Factors

• High blood pressure: the largest single contributor to heart disease deaths globally.
• High LDL cholesterol and high lipoprotein(a): drive plaque build-up in coronary arteries.
• Diabetes: doubles to triples heart attack risk; also blunts symptoms.
• Smoking (including bidis, hookah, and chewing tobacco): damages artery walls and promotes clot formation. Quitting halves your risk within a year.
• Obesity and abdominal fat: central obesity is especially harmful for South Asians.
• Physical inactivity: less than 30 minutes of moderate activity on most days raises risk.
• Unhealthy diet: diets high in trans fats, refined carbohydrates, salt, and sugar increase risk; diets rich in fruits, vegetables, whole grains, pulses, nuts, and olive or rice-bran oil reduce it.
• Chronic stress and poor sleep: including untreated obstructive sleep apnoea.
• Excess alcohol: raises blood pressure and triglycerides.
• Recreational stimulants: cocaine and amphetamines can trigger heart attacks even in young, otherwise healthy people.

Why South Asians Have a Higher Heart Attack Risk

People of South Asian origin (Indian, Pakistani, Bangladeshi, Sri Lankan, Nepalese) have a four-fold higher risk of premature heart disease compared to Europeans. Contributing factors include a higher tendency to abdominal fat (even at a "normal" BMI), insulin resistance, higher levels of lipoprotein(a), lower HDL cholesterol, and a strong genetic predisposition. This is why standard global screening cut-offs may underestimate risk in Indians, and why earlier and more aggressive risk-factor management is recommended.

Risk Factors Specific to Women

• A history of pre-eclampsia or gestational hypertension during pregnancy.
• Gestational diabetes.
• Polycystic ovary syndrome (PCOS).
• Early menopause (before age 45) or surgical menopause.
• Autoimmune conditions such as rheumatoid arthritis and systemic lupus erythematosus.
• Treatment for breast cancer that affects the heart (some chemotherapy and chest radiotherapy).

What to Do If You Suspect a Heart Attack: Step-by-Step

Step 1: Call Emergency Services Immediately

In India, call 112 (Pan-India Emergency Number), 102 (Ambulance), or 108 (where available) without delay. Tell the dispatcher you suspect a heart attack and stay on the line. Do not try to drive yourself or have a family member drive you in non-emergency traffic - ambulance crews can begin treatment on the way and alert the hospital so the cardiac team is ready.

For BLK Max Hospital emergencies, dial the 24×7 emergency helpline displayed on the hospital website. The Heart Centre and Emergency Department coordinate to begin treatment the moment the patient arrives.

Step 2: Stop, Sit, Stay Calm

Stop any activity. Sit down - ideally with the back supported and knees bent - or half-recline. Loosen tight clothing around the chest and neck. Try to breathe slowly. Walking around or "trying to shake it off" increases the strain on the heart.

Step 3: Chew Aspirin if Advised and Safe

If the dispatcher advises it, and the person is conscious, not allergic to aspirin, not actively bleeding, and not having symptoms of a stroke, chew (do not swallow whole) a single non-enteric-coated adult aspirin tablet - 162 to 325 mg. Chewing speeds absorption. Aspirin reduces clot formation and may limit damage. Do not give aspirin to children, to anyone with a known peptic ulcer or bleeding disorder, or to anyone showing signs of stroke (sudden face drooping, arm weakness, slurred speech) - in those situations, only the paramedics or hospital should decide.

Step 4: If the Person Collapses - Hands-Only CPR

If the person becomes unresponsive and is not breathing normally, start hands-only CPR while waiting for the ambulance:

• Lay the person on a firm, flat surface, on their back.
• Place the heel of one hand on the centre of the chest, between the nipples. Place the other hand on top, interlocking fingers.
• Push hard and fast - about 5 to 6 cm deep, at a rate of 100 to 120 compressions per minute. The beat of the song "Stayin' Alive" is exactly the right tempo.
• Allow the chest to fully recoil between compressions.
• Continue without stopping until emergency services arrive or the person starts to breathe normally.

You do not need to give rescue breaths if you are untrained - hands-only CPR is what is recommended for lay rescuers.

Step 5: Use an AED if Available

An Automated External Defibrillator (AED) is a portable device increasingly found in airports, metro stations, malls, and large offices in Indian cities. Switch it on, follow the spoken instructions, attach the pads to the bare chest as illustrated, and let the device analyse the heart rhythm. It will only deliver a shock if needed. Continue CPR between shocks.

Heart Attack Vital Signs During an Event

Vital signs - heart rate, blood pressure, oxygen saturation - give clues but can be misleading. Important points to know:

• Heart rate: can be fast (due to pain and stress hormones), slow (if the lower part of the heart is involved), or irregular due to arrhythmia.
• Blood pressure: may rise from stress, or fall sharply if the heart's pumping ability is impaired. A drop in blood pressure during a heart attack is a serious sign.
• Oxygen saturation: may fall below 95% if the heart is failing to deliver enough oxygen to the body. Supplemental oxygen is given in the hospital if needed.
• Normal vital signs do NOT rule out a heart attack. A patient with classic symptoms must always be evaluated, regardless of how the numbers look.

How a Heart Attack Is Diagnosed at the Hospital

ECG (Electrocardiogram)

The first and quickest test. A 12-lead ECG is performed within minutes of arrival. It identifies STEMI immediately and shows clues to NSTEMI and other rhythm problems. ECGs are sometimes repeated, because changes can evolve over hours.

Blood Tests: Troponin and Cardiac Enzymes

High-sensitivity troponin (a protein released when heart muscle is damaged) is the gold-standard blood marker for heart attack. Levels are checked on arrival and again after 1 to 3 hours. Other blood tests check kidney function, blood sugar, electrolytes, and a full blood count.

Echocardiogram

An ultrasound of the heart showing how each section is moving. Areas of damaged muscle move less than healthy ones, and the echocardiogram also screens for complications such as a leaking valve or fluid around the heart.

Coronary Angiography

A thin catheter is passed from the wrist or groin into the coronary arteries, and dye is injected so blockages can be seen directly on a special X-ray. This is both a diagnostic test and the gateway to treatment - if a blockage is found, the cardiologist can often open it during the same procedure with a balloon and stent.

Heart Attack Treatment

Reopening the Artery: Primary PCI vs Thrombolysis

For a STEMI, restoring blood flow as fast as possible is critical. There are two main approaches:

• Primary PCI (percutaneous coronary intervention): also called primary angioplasty and stenting. A balloon is used to open the blocked artery, and a metal mesh tube (stent) holds it open. This is the preferred treatment when available within 90 to 120 minutes of arrival.
• Thrombolysis (clot-busting medicines): drugs that dissolve the clot, used when PCI is not available in time. Followed by transfer to a PCI-capable hospital.

Medical Management

All heart attack patients are started on a combination of medicines that reduce clot formation, lower the heart's workload, and protect the heart muscle. These typically include aspirin and a second antiplatelet drug, a statin, a beta-blocker, an ACE inhibitor or ARB, and pain relief. The exact combination is tailored to the patient.

Coronary Artery Bypass Grafting (CABG)

If many arteries are blocked, or stenting is not technically possible, surgery may be needed. CABG uses a healthy blood vessel from elsewhere in the body to bypass the blockages and restore blood flow to the heart muscle.

The Heart Centre at BLK Max Hospital offers 24×7 cath-lab capability for primary PCI, on-site cardiothoracic surgery, and a full cardiac care unit, supported by interventional cardiologists, electrophysiologists, and CT-surgeons.

Recovery and Cardiac Rehabilitation

Recovering from a heart attack is not just about leaving the hospital - it is about rebuilding strength, confidence, and a heart-healthy way of life. A structured cardiac rehabilitation programme typically begins within a few weeks of discharge and includes:

• Supervised, gradually increasing exercise tailored to your heart function.
• Education on medicines, blood pressure and cholesterol targets, and warning signs of recurrence.
• Nutrition guidance - a Mediterranean-style or DASH diet rich in vegetables, fruits, whole grains, pulses, nuts, and olive or rice-bran oil.
• Help with smoking cessation, weight management, and stress reduction.
• Mental-health support - depression and anxiety after a heart attack are common and treatable.

Cardiac rehabilitation reduces the risk of a second heart attack and improves long-term survival. Most patients can return to work and to most usual activities within 4 to 12 weeks, depending on the severity of the attack and the type of work.

Warning signs of a repeat heart attack: any return of chest discomfort, breathlessness, sudden fatigue, palpitations, sweating, or radiating pain must be treated as an emergency - call 112 or 102 immediately.

How to Prevent a Heart Attack

Up to 80% of premature heart attacks are preventable. The principles are simple, even if they take effort to apply consistently:

• Know your numbers: blood pressure, fasting blood sugar (or HbA1c), lipid profile including LDL and lipoprotein(a), body mass index, and waist circumference. Get them checked at least once a year if you are over 35, or earlier if you have a family history.
• Quit tobacco completely: cigarettes, bidis, hookah, gutka. Quitting halves your heart attack risk within a year.
• Move more: aim for at least 150 minutes of moderate-intensity activity (brisk walking, cycling) per week, or 75 minutes of vigorous activity.
• Eat for your heart: more vegetables, fruit, pulses, whole grains, nuts, and fish; less deep-fried food, refined sugar, processed meat, and salt.
• Limit alcohol to no more than the recommended levels - and ideally avoid it.
• Manage stress and sleep: chronic stress and untreated sleep apnoea both raise heart risk. Mindfulness, yoga, and adequate sleep matter.
• Take prescribed medicines: for blood pressure, cholesterol, or diabetes, even when you feel well. They work silently to reduce risk.
• Get a heart check: especially after age 40, or earlier if you have a family history. A cardiologist can stratify your risk and recommend tailored prevention.

Conclusion

Heart attacks are one of the most common, and most treatable, medical emergencies of our time - provided they are recognised quickly. The classic picture of central chest pressure with arm pain is still the commonest presentation, but symptoms can be subtle, especially in women, older adults, people with diabetes, and young Indians who increasingly bear the brunt of premature heart disease. Whether the pain is severe or mild, whether the patient is sweating or simply "not feeling right", the rule is the same: call for help, sit down, and let trained emergency teams take over. Every minute saved is heart muscle saved.

For routine heart-health checks, risk-factor management, or post-heart-attack rehabilitation, book an appointment with the Heart Centre at BLK Max Hospital. Our cardiologists, cardiac surgeons, and rehabilitation team work together to help patients recover fully and prevent recurrence.

Frequently Asked Questions

1. What happens during a heart attack?

A coronary artery - usually narrowed by a cholesterol plaque - becomes blocked, most often by a blood clot forming on top of the plaque. The part of the heart muscle fed by that artery loses its blood and oxygen supply, and cells begin to die within minutes. Restoring blood flow as fast as possible limits the damage.

2. How painful are heart attack symptoms?

Pain can range from a mild, vague pressure to severe, crushing chest pain. Many patients describe it as squeezing, fullness, or "an elephant sitting on the chest". Some have only minor discomfort, especially women, the elderly, and those with diabetes. Severity is not a reliable guide.

3. What are the 3 earliest signs of a heart attack?

The three most common are: chest discomfort (pressure or squeezing), shortness of breath, and pain radiating to the arm, jaw, neck, or upper back. Unusual fatigue is a fourth, especially in women.

4. What is the most common cause of a heart attack?

Coronary artery disease - the build-up of cholesterol plaque inside the arteries supplying the heart. When a plaque ruptures, a clot forms and blocks the artery.

5. What is the average age for a heart attack in India?

About 45–55 years, roughly a decade earlier than Europeans. The Indian Heart Association reports that around half of heart attacks in Indian men occur under 50, and a quarter under 40.

6. What is the difference between a heart attack and a cardiac arrest?

A heart attack is a circulation problem (a blocked artery causing muscle damage); the person is usually conscious. Cardiac arrest is an electrical problem (the heart stops pumping); the person collapses and stops breathing. A heart attack can cause a cardiac arrest, which is why early treatment matters.

7. Do women experience different heart attack symptoms than men?

Often yes. Chest pain is still the most common symptom in both, but women more often have unusual fatigue, breathlessness, nausea, indigestion, dizziness, and upper-back or jaw pain — and may have no chest pain at all.

8. What is a silent heart attack?

A heart attack with no, or only very mild, symptoms. The heart muscle is still damaged. About 1 in 5 heart attacks in the US are silent, and they are more common in people with diabetes, women, and the elderly.

9. What is the role of aspirin during a heart attack?

Aspirin reduces clot formation. If the emergency dispatcher advises it, and the person is not allergic, not bleeding, and not having a stroke, chew (not swallow) a single non-enteric-coated adult tablet (162–325 mg). Do not delay calling for help while looking for aspirin.

10. How does diet affect heart attack risk?

Diets high in trans fats, deep-fried foods, refined sugar, and excess salt drive plaque build-up and raise risk. Diets rich in vegetables, fruits, whole grains, pulses, nuts, fish, and olive or rice-bran oil reduce risk.

11. What is the "golden hour" in heart attack treatment?

The first 60 minutes after symptoms begin, when restoring blood flow gives the best chance of saving heart muscle. The phrase "time is muscle" captures the urgency.

12. What is the link between sleep apnoea and heart attack?

Untreated obstructive sleep apnoea repeatedly drops oxygen levels at night, raising blood pressure, inflammation, and heart-attack risk. Treating sleep apnoea, often with a CPAP device, reduces this risk.

13. What is a mini heart attack?

A colloquial term that may mean unstable angina (a warning that an artery is critically narrowed) or a small NSTEMI (a small heart attack). Both need urgent hospital evaluation.

14. Can I test myself for a heart attack at home?

No. You cannot reliably diagnose a heart attack at home. Wearable ECGs can hint at problems but are not diagnostic. Any persistent chest discomfort, radiating pain, or unexplained breathlessness needs emergency assessment.

15. Who treats heart attack patients?

Initial emergency care is provided by paramedics and emergency-medicine doctors. Interventional cardiologists open blocked arteries with angioplasty. Cardiothoracic surgeons perform bypass surgery where needed. After discharge, a cardiologist coordinates long-term care.

16. Can you have a heart attack with normal vital signs?

Yes. Heart rate, blood pressure, and oxygen levels can all be in the normal range during a heart attack. Vital signs alone never rule it out.

17. How do I tell the difference between a heart attack and a panic attack?

Both can cause chest tightness, palpitations, breathlessness, and a sense of dread. Heart attack pain is typically pressure-like, may radiate to the arm or jaw, and is often accompanied by sweating, nausea, or dizziness. Panic attacks usually peak within 10 minutes and the pain is sharper and more localised. If in doubt, especially with risk factors, treat it as a heart attack and seek emergency care.
