Higher omega-3 status linked to reduced risk of long-term cardiac events

The scientists previously evaluated the effect of six months of omega-3 treatment after a myocardial infarction. This study assesses what happened to participants over a six-year follow-up period.

โ€œEven after two years the number of cardiac events was way lower in those who had been treated with omega-3 for just six months. Thatโ€™s a very impressive finding,โ€ said author on the paper William S. Harris, PhD, president of the Fatty Acid Research Institute (FARI); founder of OmegaQuant Analytics; and professor, department of internal medicine, Sanford School of Medicine, University of South Dakota.

However, the researchers demonstrated that the benefits of omega-3s coincided with the use of the Omega-3 Index. The Index, which was developed by OmegaQuant, is the measure of omega-3s eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA) in a personโ€™s blood. Studies show 8% is the optimal level of omega-3.

โ€œWe want to know the effects of taking omega-3 to raise the Index; not just the effects of being told to take omega-3,โ€ Dr. Harris said. โ€œIt is one thing to take an omega-3 supplement, but itโ€™s quite another to take enough to achieve a healthy target level in your own blood.โ€ ย 

Study detailsโ€‹

Approximately 360 patients who had experienced heart attacks were admitted to three Boston hospitals. Six years after the initial admissions and study, the researchers sought to determine whether there was a difference in the rate of major adverse cardiac events (MACE) in the omega-3 group as compared to the placebo group and whether the participants experienced at least a 5% increased in the Omega-3 Index while they were on treatment.
