Air pollution linked to life-threatening hardening of the arteries


Long-term exposure to air pollution may be linked to heart attacks and strokes by speeding up atherosclerosis, or “hardening of the arteries”, according to a University of Michigan public health researcher and colleagues from across the US. Sara Adar, the John Searle Assistant Professor of Epidemiology at the U-M School of Public Health, and Joel Kaufman, professor of environmental and occupational health sciences and medicine at the University of Washington, led the study that found that 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.
