Stem cells entering heart can be tracked with nano-'hitchhikers'

The promise of repairing damaged hearts through regenerative medicine—infusing stem cells into the heart in the hope that these cells will replace worn out or damaged tissue—has yet to meet with clinical success. But ...

The birth of new cardiac cells

Recent research has shown that there are new cells that develop in the heart, but how these cardiac cells are born and how frequently they are generated remains unclear. In new research from Brigham and Women's Hospital (BWH), ...

Dangerous arrhythmia analyzed in a heartbeat

Just one second, one heartbeat. That's what is needed for a new, noninvasive functional imaging technology to record data for locating the source in the heart of a dangerous cardiac arrhythmia called ventricular tachycardia ...

New method to diagnose heart arrhythmias developed

(Medical Xpress) -- Abnormalities in cardiac conduction, the rate at which the heart conducts electrical impulses to contract and relax, are a major cause of death and disability around the world. Researchers at Columbia ...

Insights into the dynamic ultrastructure of the heart

What happens below the cellular level when the heart contracts and relaxes has long been unexplored. Thanks to new ultra-high-resolution electron microscopy techniques, scientists can now watch the heart beating at almost ...

AI enables personalized treatment of myocarditis

Myocarditis (inflammation of the heart muscle) is usually caused by viruses, e.g., COVID-19. However, it can also be induced by medication, toxic substances or in the context of a rheumatological disease. Clinical assessment ...
