Air Quality and Healthy Hearts: Progress and Remaining Challenges

EPA’s Office of Research and Development, Air and Energy National Research Program is working to assess the impact and improve our understanding of air pollution morbidity and mortality in vulnerable populations, including individuals with cardiovascular disease. Exposure to airborne fine particulate matter (PM2.5) is associated with adverse cardiovascular health events including heart attacks, stroke, and death―particularly among those with pre-existing conditions. However, a better understanding of the relationship between air pollution and cardiovascular health is needed to develop strategies to protect vulnerable people with heart and vascular disease.  

This webinar provides an overview of newly published research by EPA scientists and their colleagues that helps fill key knowledge gaps. The findings, published in leading scientific journals, offer new insights into the progress made to protect at-risk individuals with chronic health problems. The research also identifies remaining environmental health challenges, such as determining risks faced from sustained exposure to elevated PM2.5 from wildfire smoke, which is being observed due to more frequent and larger wildland fires in the United States.
