Pollution levels linked to stroke-related narrowing of arteries

Air pollution has been linked to a dangerous narrowing of neck arteries that occurs prior to strokes, according to researchers. The scientists analyzed medical test records for more than 300,000 people living in New York, New Jersey or Connecticut. They found that people living in zip codes with the highest average levels of fine-particulate-matter pollution were significantly more likely to show signs of narrowing (stenosis) in their internal carotid arteries, compared to those living in zip codes with the lowest pollution levels.
