Recent studies have suggested a link between inhaled particulate matter
exposure in urban areas and susceptibility to cardiovascular events; however,
the precise mechanisms remain to be determined. New York University School of
Medicine researchers now said they have found some of the most compelling
evidence yet that long-term exposure to air pollution -- even at levels within
federal standards -- causes heart disease. Previous studies have linked air
pollution to cardiovascular disease but until now it was poorly understood how
pollution damaged the body's blood vessels.
In a mouse study, where animals breathed air as polluted as the air in New York
City, the researchers pinpointed specific mechanisms and showed that air
pollution can be particularly damaging when coupled with a high-fat diet,
according to new research published in the December 2005 issue of the Journal
of the American Medical Association.
