Description:
A heart attack occurs when there is a complete blockage of a coronary artery, or its branches, depriving a section of the heart muscle of its blood supply and therefore oxygen. Signs and symptoms may include central chest pain or discomfort, pain radiating into arm, neck or jaw, shortness of breath, grey skin colour or cold and clammy skin.
