“higher concentrations of fine particulate air pollution (PM2.5) were linked to a faster thickening of the inner two layers of the common carotid artery, an important blood vessel that provides blood to the head, neck, and brain.”
"Our findings help us to understand how it is that exposures to air pollution may cause the increases in heart attacks and strokes observed by other studies,"
“The researchers were able to link air pollution levels estimated at each person's house with two ultrasound measurements of the blood vessels, separated by about three years”
"Linking these findings with other results from the same population suggests that persons living in a more polluted part of town may have a 2 percent higher risk of stroke as compared to people in a less polluted part of the same metropolitan area,"
