This organ-on- a-chip device may improve heart disease treatment

 Singapore, Jan 3: Researchers have developed an organ-on-a-chip device that can mimic the functions of human heart and help researchers better understand atherosclerosis — the constriction of blood vessels — the leading cause of heart attacks and strokes. The new device can be used to study important inflammatory responses in cells that line the vessel in ways that could not be done in animal models as well as could improve blood testing for patients.

Atherosclerosis develops when fat, cholesterol and other substances in the blood form plaque that accumulates on the inside walls of arteries. This buildup constricts the blood vessel, causing cardiovascular diseases.(IANS)
