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 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.
