NIH Funds Project to Model Atrial Fibrillation with Heart-on-a-Chip

By Holly Ober

Creating a model of atrial fibrillation with live human heart cells on a chip is the goal of a new $6 million, five-year grant to Professor Steven George at the UC Davis Department of Biomedical Engineering and colleagues at Washington University in St. Louis.

UC Davis biomedical engineer Steven George will grow heart cells on a chip to study atrial fibrillation.

Atrial fibrillation is an irregular heartbeat caused when the heart’s upper chambers beat chaotically and out of sync with the lower chambers, leading to a variety of health problems including stroke and death. Nearly one in ten people over the age of 65 suffer from atrial fibrillation at a cost of around $6 billion.
