What is Heart Attack?

A heart attack happens when blood flow to part of the heart muscle is suddenly blocked, usually by a blood clot forming where a coronary artery has narrowed due to fatty deposits. Without prompt treatment to restore blood flow, the affected heart muscle can be permanently damaged.

Recognising the symptoms and calling emergency services immediately is critical — every minute counts in limiting heart damage. With prompt treatment, many people survive heart attacks and go on to make a good recovery, often with cardiac rehabilitation supporting their return to normal activity.
