DHA enhances heart recovery post-MIDocosahexaenoic Acid-Enhanced Autophagic Flux Improves Cardiac Dysfunction after Myocardial Infarction by Targeting the AMPK/mTOR Signaling Pathway.
We aimed to understand the role of docosahexaenoic acid (DHA) in improving heart function after a heart attack. Using both laboratory and animal models, we discovered that DHA helps cardiomyocytes survive oxygen deprivation and limits damage post-heart attack.
DHA reduced heart tissue injury and improved overall heart function. Our results showed that it promotes a protective process known as autophagy, which is linked to the AMPK/mTOR signaling pathway. This study highlights the potential of DHA in supporting heart health after a myocardial infarction.

DHA and EPA aid heart recoveryThe polyunsaturated fatty acids, EPA and DHA, ameliorate myocardial infarction-induced heart failure by inhibiting p300-HAT activity in rats.
We investigated how eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) influence heart function after a heart attack in rats. Our study showed both EPA and DHA improved heart health by reducing heart cell enlargement and preventing worsening heart failure. We found that they effectively inhibited certain cellular activities linked to heart muscle damage. Rats receiving these treatments maintained better heart function and showed less structural damage over six weeks. Ultimately, both EPA and DHA offered similar protective benefits after heart attacks.

Omega-3 shows promise in heart attacksAn Intravenous Bolus of Epa: Dha 6: 1 Protects Against Myocardial Ischemia-Reperfusion-Induced Shock.
We examined how an intravenous bolus of Omega-3, specifically a ratio of EPA to DHA at 6:1, affects heart function during myocardial ischemia-reperfusion in a rat model. Administering this Omega-3 before the reperfusion showed significant improvements in blood pressure and blood flow, while reducing markers of heart damage and inflammation. These findings suggest that while it's effective in rats, further research is necessary to see how it might work in human heart attack scenarios.

Omega-3s reduce heart attack damageComparison of the effects of EPA and DHA alone or in combination in a murine model of myocardial infarction.
We explored how two omega-3 fatty acids, EPA and DHA, affect heart attack damage by testing them in adult male rats over 14 days. After subjecting these animals to a heart injury, we measured the damage.
Our findings revealed that both EPA and DHA effectively reduced heart attack size when tested alone, while their combination didn’t show any added benefit. Notably, DHA also decreased specific cellular activities related to damage, making it a standout in promoting heart health in our model.

N-3/n-6 ratios correlate to heart attack riskAdipose tissue n-3/n-6 fatty acids ratios versus n-3 fatty acids fractions as predictors of myocardial infarction.
We explored how different types of fatty acids in our body, specifically n-3 and n-6 polyunsaturated fatty acids (PUFAs), relate to the risk of heart attacks. Analyzing data from a large cohort, we found that both n-3 fractions and their ratios with n-6 PUFAs were linked to a lower chance of a heart attack. However, the ratios showed better predictive power. This suggests tailoring our diets to improve these ratios could be a promising approach for reducing heart attack risks in the broader population.
