What To Do If Someone Is Having A Heart Attack?

What is a heart attack?

A heart attack is a severe condition where the supply of blood to the heart is suddenly blocked, usually by a blood clot. 

What To Do If Someone Is Having A Heart Attack

What are the causes?

Thrombosis (blood clotting)

Lifestyle – diet, drinking, smoking

What are the symptoms?

A sudden feeling of severe chest pain, pressure, tightness, squeezing or aching in the chest can all be signs that a person is having a heart attack. The pain can radiate into arms (yes both arms, not just the left arm) and spread to the neck, jaw, back and between the shoulders. The pain can sometimes be mistaken for indigestion.

Other symptoms include:-

  • coughing
  • nausea
  • vomiting
  • crushing chest pain
  • dizziness
  • shortness of breath called dyspnea
  • face looking grey
  • a sense of impending doom
  • feeling awful, generally
  • restlessness
  • feeling clammy and sweaty
  • shortness of breath

What to do if someone is having a heart attack?

Call 999 or 112 immediately to get help and tell them that you think someone is having a heart attack.

Keep the patient comfortable, ideally on the floor, with their knees bent and their head supported. 

If you think the casualty is in danger where they are, move them to a safer location.

If the casualty becomes unresponsive, perform CPR.
