Omega-3 fatty acids 'can aid healing after a heart attack'

2 August 2016

People recovering from a heart attack may benefit from increasing their intake of omega-3 fatty acids from fish oil.

A new study from Brigham and Women's Hospital found that post-heart attack patients taking a dose of four grams of omega-3 fatty acids daily for six months experienced a 5.8 per cent reduction in left ventricular end-systolic volume index, a clinical marker predicting patient outcomes after a heart attack.

They also saw a 5.6 per cent reduction in a measurement of scarred connective tissue formation in the non-damaged heart muscle, meaning these individuals are more likely to avoid poor outcomes and heart failure.

The findings suggest that omega-3 allows the heart to contract better, reduces fibrosis in the region that is not damaged and lowers the amount of biomarkers for inflammation, suggesting omega-3 fatty acids may have anti-inflammatory properties.

Dr Raymond Kwong, senior author of the study and director of cardiac magnetic resonance imaging at Brigham and Women's Hospital, said: "Our findings show that omega-3 fatty acids are a safe and effective treatment in improving cardiac remodeling, so it may be promising in reducing the incidence of heart failure or death."
