We examined the impact of omega-3 fatty acids, often found in fish oil, on heart attack risks, particularly in patients with high triglyceride levels. The studies indicate that while omega-3s can effectively lower triglycerides and reduce certain cardiovascular disease outcomes, including fatal heart attacks, their overall benefit remains debated. Despite extensive research demonstrating some positive outcomes, many experts still question the magnitude of their effects on heart attack prevention. Improved guidance on omega-3 supplementation is still evolving as new evidence emerges.

We explored whether icosapent ethyl (IPE), a refined omega-3 fatty acid, could lower heart attack risk among cigarette smokers. In the REDUCE-IT trial, over 8,000 statin-treated patients were randomly assigned to receive either IPE or a placebo for nearly five years.
Our findings showed that IPE significantly reduced cardiovascular events by 25%, especially for current and former smokers. Participants using IPE experienced heart attack rates similar to non-smokers, suggesting that IPE may help lessen cardiovascular risks associated with smoking.

Omega-3 reduces heart attack riskCardiovascular Outcomes With Icosapent Ethyl by Baseline Low-Density Lipoprotein Cholesterol: A Secondary Analysis of the REDUCE-IT Randomized Trial.
Study shows significant treatment benefits
We investigated whether icosapent ethyl is beneficial in reducing heart attack rates among patients with well-managed low-density lipoprotein cholesterol (LDL-C).
Analyzing data from the REDUCE-IT trial, we found that this treatment significantly lowered cardiovascular complications in statin-treated patients, regardless of their baseline LDL-C levels.
Specifically, it proved effective for those with optimal LDL-C control, showing that even patients with very low cholesterol can benefit from this omega-3 treatment in preventing serious heart events.

Omega-3 reduces heart attack riskOptimal Pair Matching Combined with Machine Learning Predicts a Significant Reduction in Myocardial Infarction Risk in African Americans Following Omega-3 Fatty Acid Supplementation.
High relevance to heart health
We explored the impact of omega-3 fatty acids on heart attack risk, focusing on African Americans. In a study analyzing data from the VITAL trial, we matched African American participants with non-Hispanic White individuals to simulate a randomized controlled trial.
Surprisingly, our findings indicated that omega-3 supplementation significantly decreased heart attack risk in African Americans but showed no benefit for non-Hispanic Whites. This highlights the importance of addressing racial differences in how individuals respond to omega-3 fish oil, urging further research in this area.

Omega-3 improves heart attack outcomesEffects of icosapent ethyl according to baseline residual risk in patients with atherosclerotic cardiovascular disease: results from REDUCE-IT.
High relevance for cardiovascular health.
We observed that icosapent ethyl, a type of omega-3 fish oil, plays a significant role in reducing heart attack risk among patients with atherosclerotic cardiovascular disease (ASCVD). In a study involving almost 5,800 participants, those taking icosapent ethyl experienced lower rates of major adverse cardiovascular events (MACE) compared to those on placebo.
The treatment showed effectiveness across all levels of cardiovascular risk, particularly benefiting those at higher risk. Overall, this suggests that incorporating icosapent ethyl could be an important option for managing heart attack risks.
