A heart attack happens when blood flow to part of the heart muscle is suddenly blocked. Recognising the signs early, and responding quickly, can save a life.
Common warning signs
The classic sign is chest pain or pressure, a tightness, heaviness or squeezing sensation in the centre of the chest. It may spread to the arm, neck, jaw or back. Other signs include breathlessness, a cold sweat, nausea and light-headedness.
Signs can be subtle
Not every heart attack is dramatic. Some people, particularly women, older adults and people with diabetes, experience milder or unusual symptoms such as fatigue or discomfort that is easy to dismiss.
What to do
If you suspect a heart attack, call 995 immediately for an ambulance. Do not drive yourself. Early treatment dramatically improves outcomes, every minute matters.
Reducing your risk
Most heart attacks are linked to modifiable risk factors. Controlling blood pressure and cholesterol, not smoking, staying active, and having regular heart screening all meaningfully lower your risk.
