Key result
Omega-3 fatty acid supplementation ameliorated pressure overload-induced cardiac dysfunction and hypertrophy in mice by increasing eicosapentaenoic acid levels and suppressing inflammation.
Why the study?
It was unknown whether omega-3 fatty acid supplementation changes cardiac fatty acid and metabolite composition, or how such changes exert beneficial effects on cardiac structure and function.
Does omega-3 fatty acid supplementation prevent cardiac dysfunction in mice exposed to pressure overload?

p-value: p=<0.05
Omega-3 fatty acid supplementation prevents pressure overload-induced cardiac dysfunction and fibrosis in mice by modulating fatty acid composition and suppressing inflammation.
Toko et al. (2020) studied Cardiac hypertrophy and heart failure. Omega-3 acid ethyl esters vs. Vehicle (0.5% methylcellulose) was evaluated on Cardiac dysfunction and hypertrophy induced by pressure overload (p=<0.05). Omega-3 fatty acid supplementation ameliorated pressure overload-induced cardiac dysfunction and hypertrophy in mice by increasing eicosapentaenoic acid levels and suppressing inflammation.
