Heart Attack

The following advice shows the treatment for a heart attack

A heart attack is most commonly caused by a sudden obstruction of the blood supply to part of the heart muscle.

The effects of a heart attack depend on how much of the heart muscle is affected; many casualties recover completely. Aspirin can be used to try to restrict the size of the clot (always check if the casualty has an allergy to aspirin first).

What to Do:


1. Call 999/112 for emergency help - Tell ambulance control that you suspect a heart attack.

2. Make the casualty as comfortable as possible to ease the strain on his heart. A half-sitting position, with their head and shoulders supported and their knees bent, is often best. Place cushions behind them and under their knees.

3. Assist the casualty to take one full does aspirin tablet (300mg in total). Advise to chew slowly. 

4. If the casualty has angina medication, such as tablets or pump-action or aerosol spray, let them administer it; help them if necessary. Encourage rest.

5. Monitor and record vital signs - breathing pulse and level of response while waiting for help to arrive. Stay calm to avoid undue stress.



If the casualty loses responsiveness, open the airway and check breathing and follow the DR ABC procedure.

Do not give the casualty aspirin if you know that they are allergic to it.
