On February 26, 2019, the Environmental Protection Agency published an article highlighting an air quality study led by Dr. Laura McGuinn from the Icahn School of Medicine at Mount Sinai and Ward-Caviness colleagues. The researchers observed that long-term exposure to PM2.5 increased the number of small, cholesterol particles in the bloodstream of the individuals who underwent cardiac catheterization and therefore may make susceptible populations more prone to cardiovascular disease. The study is the first of its kind to describe these new cholesterol biomarkers that focus on size rather than total cholesterol in the blood. The results are published in the January issue of the journal Environmental International. To read the full article click here.
