It could offer further support for use of fish oils supplements as a heart protection tool.
"We know that fish oils benefit the heart, but we don't know how exactly how this process works. We intend to look at the action of both fish oil supplements and increased fish in the diet on the way the blood vessels of the body function," said researcher Dr Jehangir Din.
Heart attacks are caused by clots blocking inflamed arteries. The Edinburgh team plans to look at the effects of fish oils on inflammation and clot breakdown.
The study, already underway and planned to complete next summer, will also assess the benefits of fish oil on smokers.
"We need smokers for this study because we know smoking can impair blood vessel function and increase inflammation, and we are interested to learn if fish oil supplementation can counteract these effects," explained Dr Din.
