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.

DHA aids post-heart attack recoveryThe polyunsaturated fatty acids, EPA and DHA, ameliorate myocardial infarction-induced heart failure by inhibiting p300-HAT activity in rats.
We explored the effects of docosahexaenoic acid (DHA) on heart attack recovery in rats. The study aimed to understand how DHA, alongside eicosapentaenoic acid (EPA), can influence heart failure following myocardial infarction (MI).
Using several groups of rats experiencing moderate heart issues, we evaluated how these omega-3 fatty acids impacted heart function. We found that both DHA and EPA effectively curtailed the hypertrophic response in heart cells. This response is a significant factor in heart failure, where heart tissue thickens and hardens.
Notably, both DHA and EPA inhibited the activity of a histone acetyltransferase called p300. This activity is linked to molecular changes that promote heart cell enlargement and fibrosis. In our analysis, we observed that these fatty acids not only preserved cardiac function but also prevented structural changes common after a heart attack.
Overall, we noted that DHA had a comparable protective effect to EPA, significantly improving heart health and reducing fibrosis in the heart tissue. As such, the findings suggest that incorporating DHA could be a heart-friendly choice post-heart attack.
