Scientists 'Find Culprit Behind Clogged Arteries'

Article excerpt

Byline: MARK PRIGG

SCIENTISTS today claimed a breakthrough that could lead to new treatments for clogged arteries.

They say they have identified a class of tiny and hitherto undiscovered lifeforms that clog arteries. These "nanoparticles" could also be responsible for a host of other illnesses, including kidney stones and ovarian cancer.

Researchers analysed healthy and clogged arteries and heart valves collected as surgical waste from two US hospitals.

Using a high-powered electron microscope, the team found tiny spheres ranging in size from 30 to 100 nanometres (billionths of a metre) - smaller than many viruses.

The nano-scale objects were present in tissue from patients with clogged arteries, but not in those from healthy individuals.

The researchers at the Mayo Clinic in Rochester, Minnesota, also say they were able to spot the nanoparticles multiplying, proving they are living organisms.

The team, whose research is revealed in the American Journal of Physiology and in New Scientist magazine, hopes that study of how the nanobacteria cause arteries to clog will lead to new treatments. …
