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 ...

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.

People with hidden pockets of fat in their muscles – similar to so-called marbling in beef – are at a higher risk of dying from heart attacks or heart failure regardless of their body weight, ...

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 ...

When you engage in regular exercise and strength training, circulation improves which eventually lowers blood pressure and boosts endurance. This helps to strengthen the heart muscle and improve ...

Here's why 40% of heart attacks show atypical symptoms like jaw pain, fatigue, and arm heaviness, and how early recognition ...

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, ...

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 ...
