In a heart attack, part of the heart muscle is starved of blood — and “time is muscle”. Recognising it and calling for help immediately gives the best chance of survival.
1. Call emergency services immediately if you suspect a heart attack.
2. Help the person sit down and rest, calm and still (a half-sitting position is often comfortable).
3. If they are not allergic and it is available, have them chew one adult aspirin (300 mg).
4. Loosen tight clothing.
5. If they become unresponsive and stop breathing normally, start CPR.
6. Note the time symptoms started.
When to see a doctor urgently
Signs: central chest pain/pressure, spreading to the arm, jaw or back, with sweating, nausea or breathlessness
Women, older people and those with diabetes may have subtler signs
Do NOT drive yourself — call an ambulance
Do not give aspirin if they are allergic to it
Call first — don’t wait it out. Do not delay hoping it passes, and do not drive yourself. Chewed aspirin (if not allergic) can help while waiting. This is not a substitute for emergency care. Call your local emergency number.
Frequently asked questions

Should I take aspirin during a heart attack?
If you are not allergic and it is to hand, chewing one adult aspirin (300 mg) can help while you wait for the ambulance. Call emergency services first.
