Atrial fibrillation, the dangerous heart rhythm disorder commonly referred to as A-fib, affects more than 10 million U.S. adults. Even with so many people affected, doctors have been stuck with the ...

The models can be used to plan surgeries and in the future could be used to help trial new drugs. A healthy heart beats at a steady rate, between 60 and 100 times a minute. That’s not the case for all ...

Scientists at the University of North Texas report a breakthrough in building tiny, lab-grown replicas of human organs. These replicas, called organoids, can mimic some functions and structures of ...

Chinese scientists have achieved an important medical breakthrough by creating the world’s first laboratory-grown sinoatrial node, often called the heart’s master conductor. This tiny part of the ...

Researchers at the University of Toronto’s Institute of Biomedical Engineering have developed a new method to mature lab-grown heart cells, so they more closely resemble adult human heart tissue. By ...

A study led by Maria Carmo-Fonseca at GIMM has helped clarify one of the main limitations of lab-grown heart cells, which are widely used around the world to study heart disease and test new drugs.

A team in the Hübner and Diecke Labs at the Max Delbrück Center have shown how human and non-human primate hearts differ genetically. The study, published in “Nature Cardiovascular Research,” reveals ...

Type 2 diabetes doesn’t just raise the risk of heart disease—it physically reshapes the heart itself. Researchers studying donated human hearts found that diabetes disrupts how heart cells produce ...
