Heart Attack Explained

A heart attack occurs when one of the arteries that supply blood to the heart is blocked. This usually occurs as a result of narrowing of these arteries, which is caused by a build-up of fatty deposits. A heart attack is sometimes called myocardial infarction, coronary thrombosis or coronary occlusion.

Heart attack is a medical emergency – immediate action can save a life. Call triple zero (000) for an ambulance if you or someone you are with experiences the warning signs of heart attack. It is always better to go to hospital than to wait until it is too late.
