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 ...

The heart is the body's hardest-working muscle. Whether you're awake or asleep, or exercising or resting, your heart is always at work. It pumps blood through arteries to deliver oxygen to organs and ...

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 ...

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 ...

Growing evidence shows that building muscle strength can have benefits for your heart, even leading to better outcomes after a heart attack. Having a higher level of leg muscle strength appears to be ...

An enduring challenge for bioengineering researchers is the failure of the heart to regenerate muscle tissue after a heart attack has killed part of its muscle wall. That dead tissue can strain the ...

Lower skeletal muscle mass was associated with an increased risk for short- and long-term mortality in patients with cardiac amyloidosis (CA). This association was particularly strong with ...

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, ...

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 ...

New research published in The European Journal of Endocrinology shows that increased total body fat mass and abdominal fat ...
