New data from China show that greater exposure to some forms of air pollution, even in the short term, is linked to an increased risk of dying from myocardial infarction.
The relationship was seen for particulate matter with an aerodynamic diameter of ≤ 2.5 µg (PM
2.5) and ≤ 10 µg (PM
10), as well as for nitrogen dioxide (NO
2), Yuewei Liu, MD, PhD (Sun Yat-sen University, Guangzhou, China), and colleagues report in their paper published online today in the
Journal of the American College of Cardiology.
Earlier studies have shown a connection between air pollution and more-chronic forms of heart disease, as well as for MI itself. This study takes a different angle, the researchers explain. “Because MI is a leading cause of death that accounts for over 30% of all deaths from ischemic heart diseases, it is of great importance to understand whether air pollutant exposures also trigger deaths from MI.”
