Omega-3 fatty acids, particularly eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), have been widely studied for their potential benefits in reducing cardiovascular risks. This synthesis aims to consolidate findings from multiple research papers to determine whether omega-3 supplementation effectively reduces cardiovascular risks.
Reduction in Cardiovascular Events and Mortality:
Primary vs. Secondary Prevention:
Dose-Response Relationship:
Mixed Evidence on Overall Mortality and Cardiovascular Events:
Specific Cardiovascular Outcomes:
The evidence suggests that omega-3 supplementation, particularly at higher doses and in secondary prevention settings, can reduce specific cardiovascular risks such as cardiac mortality, MACE, and MI. However, the overall impact on all-cause mortality and general cardiovascular events remains less clear, with some studies indicating minimal benefits. The effectiveness of omega-3 supplementation may vary based on the type of fatty acid (EPA vs. DHA), dosage, and the baseline cardiovascular risk of the population.
