Heartbeat out of sync

Life-threatening cardiac arrhythmias often occur after a heart attack, as the scar tissue can interfere with the spread of electrical impulses that activate the heart. An international research team under the leadership of ...

Beating heart patch is large enough to repair the human heart

Biomedical engineers at Duke University have created a fully functioning artificial human heart muscle large enough to patch over damage typically seen in patients who have suffered a heart attack. The advance takes a major ...

MicroRNA molecule can cause pathological changes in the heart

Cardiac fibrosis involves an increase of connective tissue in the cardiac muscle, causing a loss of function. A team of researchers at the Technical University of Munich (TUM) has now discovered that microRNA 29 (miR-29) ...

Muscles out of the spray can

An artificial heart would be an absolute lifesaver for people with cardiac failure. However, to recreate the complex organ in the laboratory, one would first need to work out how to grow multi-layered, living tissues. Researchers ...

Magnetic cellular Legos for the regenerative medicine of the future

By incorporating magnetic nanoparticles in cells and developing a system using miniaturized magnets, researchers at the Laboratoire Matière et Systèmes Complexes (CNRS/Université Paris Diderot) and collaborators have created ...

Child heart patients treated for rare surgical infection

At least a dozen children who had heart surgery at Children's Hospital New Orleans between late May and July have infected incisions, apparently from contaminated equipment.

A virtual heart to simulate arrhythmia

A group of researchers from MIPT and Ghent University (Belgium) has developed the first realistic model of the complex cardiac microstructure. The researchers hope that the model will elucidate the causes of fibrosis, which ...
