Researchers boosted levels of a heart-healing hormone in mice and pigs with a single injection of a new, experimental form of ...

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 ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. People with hidden pockets of fat in their muscles – similar to so-called marbling in beef – are at a higher risk of dying from ...

A groundbreaking study conducted by researchers from the Duke-National University of Singapore (Duke-NUS) Medical School has shown promising results in repairing damaged heart muscle by transplanting ...

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 ...

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 ...

Researchers from the group of Jeroen Bakkers at the Hubrecht Institute (KNAW) have found that the muscle cells in the heart of zebrafish change their metabolism, the way in which they generate energy, ...

Every heart muscle cell, or cardiomyocyte, is studded with tiny, intricate structures called dyads. The dyads are like orchestra conductors: They coordinate incoming electrical signals with release of ...
