New insights into the development of heart disease therapeutics

The heart of a neonatal mouse is capable of self-repair after tissue damage. However, this ability disappears during the first week of life. Researchers at the University of Helsinki investigate the molecular mechanisms underlying ...

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 ...
