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 ...

According to the research, the protein seems to sense stress on the muscle cells and adjusts sarcomere shortening—and consequently, muscle contraction—based on how hard the heart needs to work. If ...

The heart is the only muscle that contracts and relaxes continuously over a lifetime to pump oxygen-rich blood to the body's organs. Researchers at UT Southwestern Medical Center now have identified a ...

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 ...

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 ...

ROCKVILLE, MD – In a surprising discovery, scientists have found that the heart possesses "sweet taste" receptors, similar to those on our tongues, and that stimulating these receptors with sweet ...

Unlike humans, great apes do not appear to develop coronary artery disease. Rather, their heart muscle undergoes a fibrotic, or thickening, process which causes poor contraction and a susceptibility ...

Researchers from the Heart Center of the University Medical Center Göttingen (UMG) led by Priv.-Doz. Dr. Sören Brandenburg have identified a protein that plays a central role in the heart's adaptation ...

The cardiac troponin test detects damage to the heart muscle. Troponin is a protein that appears in the blood only when the heart muscle is damaged, as in a heart attack. There are other causes of ...
