Scientists sifted through 19 studies which had involved more than 45,000 participants from 16 different countries. Of the study participants, about, 8,000 were affected by at least one heart attack event later in life, while more than 2,700 of these cases resulted in death. Researchers found a statistically significant link between omega-3 consumption and lower risk of developing a fatal heart attack. Participants who had the highest levels of the fatty acid in their system were 25 percent less likely to die of a heart attack.
The findings were consistent even after the research team adjusted the study results for other factors that may influence study outcomes including age, sex, race, history of heart disease, the risk of diabetes, cholesterol-lowering drug and aspirin use. The new study was based on Omega-3 blood levels not self-reports as some previous research had been. The findings were published Monday in the journal JAMA Internal Medicine.
