\"Freeway\"<\/img><\/a>
<\/br>
\nLos Angeles residents living near freeways experience a hardening of
\nthe arteries that leads to heart disease and strokes at twice the rate
\nof those who live farther away, a study has found. <\/p>\n

The paper is the
\nfirst to link automobile and truck exhaust to the progression of
\natherosclerosis — or the thickening of artery walls — in humans. The
\nstudy was conducted by researchers from USC and UC Berkeley, joined by
\ncolleagues in Spain and Switzerland, and was published this week in the
\njournal PloS ONE<\/a>.<\/p>\n

Researchers
\nused ultrasound to measure the wall thickness of the carotid artery in
\n1,483 people who lived within 100 meters, or 328 feet, of Los Angeles
\nfreeways. Taking measurements every six months for three years, they
\ncorrelated their findings with levels of outdoor particulates — the
\ntoxic dust that spews from tailpipes — at the residents\u2019 homes. <\/p>\n

They
\nfound that artery wall thickness accelerated annually by 5.5
\nmicrometers — one-twentieth the thickness of a human hair — or more
\nthan twice the average progression in study participants.<\/p>\n

The findings show, according to co-author Howard N. Hodis, director of the Atherosclerosis Research Unit at
\nUSC\u2019s Keck School of Medicine, \u201cthat environmental factors may play a
\nlarger role in the risk for cardiovascular disease than previously
\nsuspected.\u201d<\/p>\n
