Many promising therapies fail because preclinical models do not fully capture the complexity of the human heart. A new review ...

The heart has long been thought to be controlled solely by the autonomic nervous system, which transmits signals from the brain. The heart's neural network, which is embedded in the superficial layers ...

We believe the human heart evolved away from the trabeculated structure seen in the other great apes to enhance its ability to twist and contract more efficiently. This increased twisting motion, ...

Researchers have identified a key protein that may help failing hearts regain function, offering new insight into why some hearts recover while others do not. The discovery comes from studying ...

A team of biomechanical engineers at the University of New South Wales, working with a colleague from Queensland University of Technology and cardiac surgeons at St Vincent's Hospital, Sydney, has ...

New research from Karolinska Institutet and Columbia University shows that the heart has a mini-brain – its own nervous system that controls the heartbeat. A better understanding of this system, which ...

AN INTERNATIONAL team of scientists have provided new insight into the Frank-Starling mechanism; a fundamental aspect of human heart function. The Frank-Starling mechanism described more than a ...

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.

"Understanding this system better could lead to new insights into heart diseases and help develop new treatments for diseases such as arrhythmias." The study was conducted on zebrafish, an animal ...
