A single injection of a new, experimental form of self-amplifying RNA prolonged hormone synthesis for many weeks, healing the heart in pigs.

New injection helps body produce heart protecting hormone for weeks after heart attack, improving recovery potential.

When heart muscle gets damaged, the result is often permanent. Unlike other muscles in the body, the heart has long been believed to lack the ability to heal itself. But recent research suggests that ...

After a heart attack, cardiologists can reopen blocked vessels and restore blood flow, but the muscle cells that died will never be replaced.

Study shows greater muscle area in men leads increased risk of heart disease; it's different for muscle density. Body composition -- often expressed as the amount of fat in relation to muscle -- is ...

Large, human cardiac-muscle patches created in the lab have been tested, for the first time, on large animals in a heart attack model. This clinically relevant approach showed that the patches ...

Some heart failure patients with artificial hearts have been able to regenerate heart muscle, potentially paving the way for future heart failure treatment options, according to a study published Nov.

Researchers have shown that cardiac scar tissue (fibroblasts) can be directly reprogrammed to heart muscle cells (cardiomyocytes) in mice. By treating mice post-heart attack with a virus carrying ...
