10 Warning Signs of a Heart Attack You Should Never Ignore

Heart disease remains the leading cause of death globally. Recognising the early warning signs of a heart attack is critical.

1. Chest Pain or Pressure

A feeling of tightness, pressure, squeezing, or pain in the centre of the chest lasting more than a few minutes.

2. Pain Radiating to the Arm, Neck or Jaw

Discomfort that spreads from the chest to the left arm, shoulder, neck, jaw, or back.

3. Shortness of Breath

Difficulty breathing, even without exertion or chest pain.

4. Cold Sweats

Breaking out in a cold sweat without obvious cause.

5. Nausea or Vomiting

Unexplained nausea, especially combined with other symptoms.

6. Lightheadedness or Dizziness

Sudden dizziness or feeling faint.

7. Extreme Fatigue

Unusual tiredness that can appear days or weeks before a heart attack.

8. Palpitations

Irregular or rapid heartbeat.

9. Swelling in the Legs or Feet

Oedema caused by poor circulation or heart failure.

10. Silent Heart Attacks

In some people — especially women and diabetics — heart attacks can occur with minimal or no pain.
