These overlooked muscles could play a critical role in circulation and cardiovascular health.

For the first time, scientists have shown that heart muscle cells can regrow after a heart attack in humans, a process 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 ...

Both swimming and running improve fitness, but scientists found one may trigger deeper changes in heart structure and ...

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 ...

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 ...

Can weight loss reverse heart failure? A new study shows that heart muscle cells regain strength and muscle contractions ...

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 ...

Skeletal muscle is the type of muscle that controls movement. Problems with these muscles can be minor, life-threatening, or ongoing problems that make it hard to perform basic daily activities.

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, ...
