The World Health Organization has identified air pollution as the leading environmental health risk globally, responsible for 4.2 million deaths per year. With more than half attributed to ischemic heart diseases and strokes. Air pollution can impact the cardiovascular system through processes such as inflammation, systemic and pulmonary oxidative stress, or dysfunction of the autonomic nervous system.
An innovative investigation reveals a significant relationship between blood lipid levels and exposure to air pollutants. This correlation suggests a connection between air pollution and atherosclerosis. A condition characterized by the accumulation of fats, cholesterol, and other substances within arteries and their walls.
The study, recently published in the European Journal of Clinical Investigation, discovers that air pollution, commonly linked to respiratory problems, also negatively affects blood lipid levels. Potentially increases the risk of heart diseases.
The research, based on data from 4,647 adults in Spain collected from the national di@bet.es study between 2008-2010 and 2015-2017, aimed to understand the prevalence of type 2 diabetes and other metabolic diseases. In addition to physical examinations and blood samples, information on various factors such as age, gender, educational level, lifestyle habits, and exposure to air pollutants was collected.
The study analyzed how exposure to air pollutants, such as fine particles and nitrogen dioxide, is related to blood lipid levels. A significant connection was found between pollution exposure and lipid profiles. It suggested a higher risk of cardiovascular diseases, highlighting the importance of public health policies.
