Changing what heart cells eat could help them regenerate

Switching what the powerhouses of heart cells consume for energy could help the heart regenerate when cells die, a new study led by UT Southwestern researchers suggests. The finding, published in the Feb. 20, 2020, Nature Metabolism, could open whole new avenues for treating a variety of conditions in which heart muscle becomes damaged, including heart failure caused by viruses, toxins, high blood pressure, or heart attacks.
