In this study, the utility of sodium propionate for accentuating changes in cardiac metabolism is evaluated. The study is performed using a murine model of cardiac hypertrophy and employs hyperpolarized magnetic resonance spectroscopy, mass spectrometry and a biochemical assay to determine the cardiac redox state. Results show propionate modulates cardiac metabolism across a range of different concentrations.
