Fine particulate pollution linked to atherosclerosis

Researchers linked fine particulate matter (PM2.5) levels at participants’ individual homes with two ultrasound measurements of the common carotid artery over three years.

They found people living with higher levels of pollution had a faster rate of carotid intima-medial thickness progression than other residents of the same city.

And air quality improvement during the study slowed IMT progression.

The researchers estimated individuals in polluted areas had a 2% increased risk of stroke compared to others.
