Exposure to air pollution for a long time accelerates the development of atherosclerosis, "

Associate Professor of Epidemiology at UM School of Public Health, John Searly, together with Professor of Environmental and Occupational Health Sciences at the University of Washington and Joel Kaufman, conducted a study in which it was found that exceeded levels of PM2. 5 - fine particles of air pollution - are associated with the rapid thickening of an important blood vessel that provides blood flow to the neck, head and brain, or rather the two inner layers of the carotid artery.

While the reduction in the amount of microparticles polluting the air over time contributed to a gradual decrease in the thickness of the blood vessel.

The degree of development of atherosclerosis in the arteries is determined by the thickness of this blood vessel.. This condition even applies to people without obvious symptoms of cardiovascular disease.. "

5362 residents of 6 major US cities aged 45-84 participated in a study aimed at studying the relationship of atherosclerosis with air pollution.

Estimating the level of air pollution in each volunteer's home involved ultrasonic measurements of blood vessels at intervals of three years..

Even after controlling for factors such as smoking, the researchers found that the thickness of the carotid arteries increased by an average of 14 micrometers per year.. Meanwhile, people who were exposed to excessive levels of air pollution in their home had thickened blood vessels much faster than other participants living in the same region of the capital..
