When a muscle contracts, the parts of a sarcomere "shorten" and come closer together. Each cardiac muscle cell can have over 5,000 sarcomeres, which compounds both the shortening and relaxation events ...

Adult heart muscle has long been treated as tissue with very little capacity to replace cells lost during a heart attack. A new observation in living human samples complicates that picture: heart ...

In a new research report, a team of scientists led by Johns Hopkins Medicine say people with severe obesity and a common type of heart failure experience weakened heart muscles, and that losing weight ...

A team of researchers have discovered that a mutation in a ribosomal protein found specifically in heart and skeletal muscle leads to impaired cardiac contractility in mice. The mutation was found to ...

No one can live without a heart pumping blood to the rest of the body. New research from the University of Missouri School of Medicine reveals more information about this vital function and how it’s ...

Researchers fused human iPS cells to create tetraploid lines whose derived cardiomyocytes show larger size, adult-like gene ...

Newswise — Since early in the pandemic, COVID-19 has been associated with heart problems, including reduced ability to pump blood and abnormal heart rhythms. But it’s been an open question whether ...
