Cardiac disease continues to be a major cause of death in the Western world. Several preventive measures can be implemented to reduce the risk of a cardiac event.
One of these measures is diet. A diet that is rich in fatty fish provides a considerable quantity of omega-3-fatty acids.

These fatty acids have been shown to reduce the risk of cardiac events such as arrhythmias, stroke and thrombosis.

The nurse has a key health education role to play in the promotion of healthy eating in order to reduce the incidence of cardiac events in patients with existing cardiac disease.
