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 at UT Southwestern Medical Center have identified a previously unrecognized small protein in cells of the human heart that plays a key role in heart muscle contraction. The protein is made ...

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 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 ...

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 heart is a muscle like no other, beating 60 to 100 times per minute on average, around the clock. But when it grows weak, it can lead to serious problems: from debilitating shortness of breath and ...

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 ...

To build the model, scientists used cardiac muscle and connective tissue cells from rats. Scientists in Canada have developed a three-dimensional "heart-on-a-chip" that could mark a major step forward ...

Most people view their calf muscles solely through the lens of aesthetics or athletic power, but they are actually critical components of your circulatory system. Often referred to by medical ...
