Thousands of heart attack victims every year will be prescribed fish oil supplements under new guidelines published by a health watchdog.

Doctors are being urged to issue a one-a-day pill to patients who have had a heart attack in the past three months and are not getting enough oily fish in their diet.

The National Institute for Health and Clinical Excellence (Nice) found a specific supplement cut the risk of patients suffering another attack.

Omacor - a concentration of omega-3-acid ethyl esters - has been shown to cut the risk of a patient dying suddenly by up to 45%.
