A heart attack is one of the most time-sensitive medical emergencies. Every minute of delay in treatment increases the risk of permanent damage to the heart muscle. Yet many patients in Rohini and across Delhi arrive at the hospital hours after their symptoms begin, often because they did not recognise the warning signs or were unsure whether their symptoms warranted an ambulance call.
Understanding the difference between symptoms that require immediate emergency care and those that can be evaluated in a scheduled cardiology consultation could save your life or the life of someone close to you.
Classic vs Atypical Heart Attack Symptoms
Classic symptoms
The most widely recognised presentation of a heart attack includes:
- Chest pain or tightness — a heavy, squeezing or pressure-like sensation in the centre or left side of the chest, often lasting more than a few minutes
- Pain radiating to the left arm, jaw, neck, back or upper abdomen
- Profuse sweating — cold, clammy sweat unrelated to physical exertion or weather
- Breathlessness — difficulty breathing that may occur with or without chest pain
- Nausea or vomiting
- Lightheadedness or feeling faint
Atypical symptoms — especially in women
Not every heart attack presents with crushing chest pain. Atypical symptoms are more common in women, elderly patients and people with diabetes. These include:
- Unusual fatigue or exhaustion that comes on suddenly
- Discomfort or burning sensation in the upper abdomen, sometimes mistaken for acidity or indigestion
- Jaw pain or toothache without dental cause
- Isolated breathlessness without obvious chest pain
- Pain between the shoulder blades
- A sense of impending doom or severe anxiety
Important: Women are more likely than men to experience atypical symptoms such as jaw pain, nausea, back pain and unexplained fatigue. Because these symptoms do not match the "classic" heart attack picture, women often delay seeking help. Any new, unexplained symptom that feels different from your usual state of health deserves urgent evaluation.
When to Call an Ambulance Immediately
Call emergency services (112 in India) or get to the nearest hospital with a cardiac catheterisation laboratory without delay if you experience any of the following red flags:
- Chest pain or pressure lasting more than five minutes that does not go away with rest
- Chest pain accompanied by sweating, breathlessness, nausea or lightheadedness
- Pain spreading from the chest to the arm, jaw, neck or back
- Sudden severe breathlessness, especially at rest or with minimal activity
- Loss of consciousness or near-fainting with any of the above symptoms
- Known heart disease with new, worsening or unusual symptoms
Do not drive yourself. Call an ambulance or have someone drive you. Chew an aspirin (325 mg) if you are not allergic to it while waiting for help — this is one of the most important first-aid steps during a suspected heart attack.
Time is critical. In a heart attack caused by a sudden blockage (STEMI), the goal is to open the blocked artery within 90 minutes of arrival at a hospital capable of performing primary angioplasty. Every 30-minute delay in treatment increases the risk of irreversible heart muscle damage.
When to Schedule a Cardiologist Visit Instead
Not every chest discomfort is a heart attack. Some symptoms, while they should not be ignored, can be evaluated through a planned consultation rather than an emergency visit:
- Mild chest discomfort that lasts a few seconds and resolves completely on its own
- Chest pain that occurs only with specific body movements or positions and is reproducible by pressing the chest wall
- Occasional palpitations (awareness of heartbeat) without dizziness or fainting
- Exertional breathlessness that has been gradually worsening over weeks
- A family history of heart disease and you want a preventive cardiac check-up
- Abnormal cholesterol, blood pressure or blood sugar levels that need cardiovascular risk assessment
When in doubt, err on the side of caution. It is always better to visit an emergency department and be told your heart is fine than to stay at home during a genuine cardiac event.
What Happens at the Emergency Room
When a patient arrives at the emergency department with suspected heart attack symptoms, the medical team follows a rapid, structured protocol:
- ECG (Electrocardiogram) — typically done within the first 10 minutes. It records the heart's electrical activity and can identify whether a heart attack is occurring and which type it is (STEMI or NSTEMI).
- Blood tests — Troponin — a protein released into the blood when heart muscle cells are damaged. Elevated troponin levels confirm heart muscle injury. Serial measurements may be taken over a few hours.
- Medications — aspirin, blood thinners, pain relief and other supportive medicines are started immediately.
- Coronary angiography — if the ECG and blood tests confirm a heart attack, an emergency coronary angiogram is performed to locate the blocked artery. If a significant blockage is found, primary angioplasty and stenting may be performed in the same sitting to restore blood flow.
The entire process from arrival to opening the blocked artery can take less than 60 to 90 minutes in a well-equipped cardiac centre. This is why reaching the right hospital quickly is so important.
Risk Factors — Who Should Be Extra Vigilant
Certain individuals have a higher baseline risk of a heart attack and should be especially alert to any new or unusual symptoms:
- Age — men over 45 and women over 55 are at increased risk, though heart attacks are increasingly seen in younger adults in India
- Family history — a first-degree relative (parent or sibling) with early heart disease (before age 55 in men, 65 in women)
- Diabetes — damages blood vessels over time and may blunt pain perception, making heart attacks harder to recognise
- Hypertension — chronically elevated blood pressure accelerates atherosclerosis
- Smoking — one of the strongest modifiable risk factors for coronary artery disease
- High cholesterol — particularly elevated LDL cholesterol
- Obesity and sedentary lifestyle
- Chronic stress — high levels of sustained psychological stress contribute to cardiovascular risk
If you have two or more of these risk factors, a preventive cardiac evaluation — including an ECG, echocardiogram, lipid profile and stress test where indicated — can help identify problems before they become emergencies.
Book a Cardiac Check-Up
Prevention is always better than emergency treatment. If you have risk factors for heart disease or have been experiencing symptoms that concern you, a comprehensive cardiac evaluation can provide clarity and peace of mind.

Frequently Asked Questions
Can a heart attack happen without chest pain?
Yes. A heart attack can present with breathlessness, nausea, jaw pain, arm pain or extreme fatigue without any chest pain. This is more common in women, elderly patients and people with diabetes. These are called silent or atypical heart attacks, and they are just as dangerous as those with classic chest pain.
How do I tell the difference between a heart attack and acidity?
Heart attack pain is usually a pressure or squeezing sensation in the chest, often accompanied by sweating, breathlessness or pain in the arm or jaw. Acidity typically causes a burning sensation behind the breastbone that worsens after meals and may improve with antacids. However, the two can feel very similar. If you are unsure, treat it as a cardiac emergency and seek immediate medical help.
What should I do if someone near me is having a heart attack?
Call 112 immediately. Help the person sit or lie down in a comfortable position. If they are not allergic to aspirin, give them a 325 mg aspirin tablet to chew. Do not give water to wash it down — chewing allows faster absorption. If the person becomes unresponsive and stops breathing, begin CPR (chest compressions at a rate of 100 to 120 per minute) until emergency help arrives.
At what age should I start getting heart check-ups?
General cardiovascular screening — including blood pressure, cholesterol and blood sugar — is recommended from age 30 onwards, especially if you have a family history of heart disease or other risk factors. In India, where coronary artery disease tends to occur at a younger age compared to Western populations, early screening is particularly important. A cardiologist can advise on the frequency and type of tests based on your individual risk profile.
