Microtubules, part of heart muscle cells' internal "skeleton," help determine how the heart changes shape under stress, and a ...

When the heart is injured, as in a myocardial infarction, the damaged heart muscle cannot regenerate—instead, scar tissue forms. Cardiomyocytes, the heart muscle cells that generate contractile force, ...

A newly discovered pathway between the heart and brain may explain why healthy people faint. The pathway appears to carry signals from the heart's lower pumping chambers to an area of the brainstem ...

A DZHK research team at the University Medical Center Mainz has discovered a new signaling pathway of the coagulation system that controls scar formation after a heart attack. If this signaling ...

CHAPEL HILL, N.C. – Researchers at the UNC School of Medicine, UNC McAllister Heart Institute, and the UNC Lineberger Comprehensive Cancer Center characterized the expression of thousands of cardiac ...

Incorporating high-sensitivity cardiac troponin (hs-cTn) testing into the traditional HEART pathway may improve detection of acute MI in patients presenting to the emergency department (ED) with chest ...

Two seemingly disparate signaling pathways -- one that controls organ size in fruit flies and another important for the growth of embryos -- interact in embryonic mouse hearts to restrict cell ...

Scientists at The Ohio State University have made an important discovery that could help doctors better treat dangerous heart ...
