The 7 warning signs of a heart attack include chest pain or pressure, pain spreading to the arms or jaw, shortness of breath, cold sweating, nausea, unusual tiredness, and dizziness. These symptoms can start suddenly or develop slowly. Recognising them early and getting emergency medical help can save your life.

What Is a Heart Attack?

A heart attack happens when blood flow to part of the heart becomes blocked, usually because of a blood clot in a coronary artery. Without enough oxygen, the heart muscle begins to get damaged.

Heart attack symptoms are not always severe or obvious. Some people experience intense chest pain, while others notice mild discomfort, breathlessness, or unusual fatigue.

Knowing the early warning signs of a heart attack can help you recognise an emergency and act quickly.

What Are the 7 Warning Signs of a Heart Attack?

Here are seven important symptoms you should never ignore.

Warning sign	What it may feel like
1. Chest pain or pressure	Tightness, squeezing, heaviness, or discomfort in the chest
2. Pain spreading to other areas	Pain in one or both arms, shoulders, back, neck, or jaw
3. Shortness of breath	Difficulty breathing, even while resting
4. Cold sweating	Sudden, unexplained sweating with clammy skin
5. Nausea or vomiting	Feeling sick, vomiting, or experiencing indigestion-like discomfort
6. Unusual tiredness	Sudden or unexplained weakness and exhaustion
7. Dizziness or lightheadedness	Feeling faint, unsteady, or as though you might pass out

Not everyone experiences all seven symptoms. A heart attack may occur with only one or two warning signs.

1. Chest Pain or Pressure

Chest discomfort is one of the most common heart attack symptoms in adults. It may feel like pressure, squeezing, fullness, burning, or heaviness in the centre of the chest.

The discomfort may last several minutes or disappear and return. Do not assume it is acidity, gas, or muscle pain without proper medical assessment.

2. Pain Spreading to the Arm, Jaw, Neck, or Back

Heart attack pain can move beyond the chest. You may feel discomfort in one or both arms, your shoulders, jaw, neck, or upper back.

Sometimes, this spreading pain occurs with little chest discomfort. Unexplained pain accompanied by sweating, nausea, or breathlessness needs urgent medical attention.

3. Shortness of Breath

You may struggle to breathe while walking, climbing stairs, or even sitting still. Breathlessness can occur with chest pain or appear before other symptoms.

Sudden, unexplained breathing difficulty should never be ignored, particularly when accompanied by weakness, sweating, or chest discomfort.

4. Cold Sweating

Breaking into a cold sweat without exercise, heat, or another clear reason can be a warning sign. Your skin may feel cool, damp, or clammy.

If sudden sweating occurs alongside chest discomfort, nausea, or dizziness, seek emergency medical care immediately.

5. Nausea, Vomiting, or Indigestion-Like Discomfort

A heart attack can cause nausea, vomiting, or discomfort in the upper abdomen. Some people mistake these symptoms for acidity or indigestion.

Pay attention when these symptoms appear unexpectedly or occur with chest pressure, breathlessness, or cold sweating.

6. Unusual Tiredness or Weakness

Sudden exhaustion or unusual weakness can sometimes signal a heart problem. Some people, particularly women, report unexplained fatigue before or during a heart attack.

Feeling tired alone does not mean you are having a heart attack. However, sudden or unusual fatigue combined with other warning signs needs urgent assessment.

7. Dizziness or Lightheadedness

A heart attack may cause dizziness, lightheadedness, or a feeling that you might faint. This can happen when the heart cannot maintain adequate circulation.

If dizziness occurs with chest pain, breathlessness, sweating, or fainting, treat it as an emergency.

Signs of a Heart Attack in Men and Women

Heart attacks can affect men and women differently, although there is considerable overlap in their symptoms.

Men may experience	Women may experience
Chest pressure or tightness	Chest pressure or discomfort
Pain spreading to the arm or jaw	Pain in the back, shoulder, arm, or jaw
Shortness of breath	Shortness of breath
Cold sweating	Nausea, cold sweating, or unusual fatigue
Nausea or dizziness	Dizziness, weakness, or indigestion-like discomfort

Important: Chest pain is common in both men and women. Women may also experience less obvious symptoms, so the absence of severe chest pain does not rule out a heart attack.

What Should You Do If You Notice Heart Attack Symptoms?

If you suspect a heart attack, do not wait for symptoms to become severe.

1. Call 112 in India for emergency assistance and an ambulance.
2. Stop physical activity and sit down in a comfortable position.
3. Do not drive yourself to the hospital. Wait for emergency medical assistance.
4. Follow the emergency operator’s instructions. Ask about aspirin only if appropriate, especially if you have allergies, bleeding risks, or other medical restrictions.
5. If the person becomes unresponsive and is not breathing normally, begin CPR and use an AED if available, following emergency guidance.

Quick treatment can limit heart muscle damage and improve the chances of recovery. Do not delay seeking help to search for symptoms online or arrange a routine appointment.
