Animal Tests Show Promise for Restoring Heart to More Youthful Condition, Even After Heart Attack
Briefly

Scientists are working on innovative therapies to regenerate heart muscle after damage caused by cardiac injuries. Initial animal studies show promising results in restoring heart function.
Researchers are investigating the use of microRNA to enable cardiac cells to multiply, with early experiments indicating this could significantly enhance heart performance post-injury.
Stem cell therapies hold potential for regenerating heart cells, as University of Southern California's team demonstrated with macaques recovering full pumping function, despite challenges with arrhythmias.
Future treatments rely on successful clinical trials in humans, motivating ongoing research to address heart disease, the leading cause of death in the US.
