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 ...

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 ...

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 ...

The human heart, often described as the body's engine, is a remarkable organ that tirelessly beats to keep us alive. At the core of this vital organ, intricate processes occur when it contracts, where ...

Researchers found that cardiomyocytes in human hearts show increased mitotic activity after myocardial infarction, the medical term for a heart attack. In other words, surviving heart muscle cells can ...

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 ...

Working with heart muscle cells from diabetic rats, scientists at Johns Hopkins have located what they say is the epicenter of mischief wreaked by too much blood sugar and used a sugar-gobbling enzyme ...

Newswise — 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 ...
