Omega-3 fatty acid prevents the development of heart failure by changing fatty acid composition in the heart
Abstract Some clinical trials showed that omega-3 fatty acid (FA) reduced cardiovascular events, but it remains unknown whether omega-3 FA supplementation changes the composition of FAs and their metabolites in the heart and how the changes, if any, exert beneficial effects on cardiac structure and...
