Know the Signs. Act Fast.

If you think someone is having a heart attack, every minute matters. Learn the warning signs and what to do immediately.

Recognise the Warning Signs

The signs of a heart attack can vary. Pay attention to persistent or unusual symptoms.

Chest Discomfort

A feeling of pressure, tightness or squeezing in the centre of the chest that lasts more than a few minutes or goes away and comes back.

Shortness of Breath

Difficulty breathing with or without chest discomfort. This may occur while resting or with minimal activity.

Radiating Pain

Pain or discomfort spreading to the arms, shoulder, jaw, back or stomach. The sensation may be dull, aching or sharp.

Other Symptoms

Cold sweat, nausea, light‑headedness, or an overwhelming sense of anxiety can accompany a heart attack.

What to Do Immediately

Fast action can save a life. Follow these steps if you suspect a heart attack:

  1. Call your local emergency number right away. Tell the dispatcher you suspect a heart attack and follow their instructions.
  2. If the person can chew and swallow and has no contraindications, assist them to take one adult aspirin (325 mg) or two to four low‑dose tablets (81 mg).
  3. Help the person to rest comfortably and reassure them until medical professionals arrive. Do not drive them to hospital yourself.

Why Speed Matters

During a heart attack, blood flow to the heart muscle is blocked. Prompt action helps restore circulation, reducing damage and improving the person’s chance of survival. The sooner treatment begins, the better the outcome.
