We explored how eicosapentaenoic acid (a type of omega-3 fatty acid) can play a role in improving heart health, particularly in individuals with heart failure. Our analysis involved a network meta-analysis of numerous randomized controlled trials, focusing on the effects of eicosapentaenoic acid on heart function.
The findings showed that high doses of omega-3 supplements, specifically between 2000 to 4000 mg per day, taken for at least a year, can significantly enhance left ventricular ejection fraction, which is an important measure of heart function. This is encouraging news for patients struggling with heart failure, as a better ejection fraction can lead to improved heart health.
We also observed improvements in peak oxygen consumption, offering further evidence of how eicosapentaenoic acid can boost cardiac performance. Importantly, we found no significant increases in dropout rates or overall mortality among those taking omega-3 supplements compared to those not taking them. This suggests that the benefits come without added risks.
Overall, our research underscores the potential of long-term, high-dose eicosapentaenoic acid supplementation as a supportive treatment option for heart failure patients, advocating for further studies to confirm these promising results and help refine treatment recommendations.
