2023 Study Shows that Risk of Fatal Heart Attacks May Double When Temperatures and Particulate Matter Increase

According to a 2023 study of over 200,000 heart attack deaths in China published in the American Heart Association’s flagship journal Circulation, the risk of death from heart attack may double due to the combination of extreme heat and high levels of fine particulate pollution.

In this article, air quality experts from global air filtration manufacturer and engineering company Camfil explain the findings of the study and their implications for

Particulate Matter Air Pollution and Heart Health

Previous research in the field has established that fine particulate matter exposure, both short- and long-term, is linked to an increased risk of heart disease, stroke, and other cardiovascular issues.

Fine particulate matter, which is defined as any solid or liquid particle suspended in the air with a diameter of 2.5 microns or less, is small enough to bypass the natural defenses in the lungs and trachea, allowing it to be inhaled deep into the lungs and cause irritation to blood vessels around the heart.

According to scientific statements and policy statements from the American Heart Association, addressing air pollution and its effects on heart disease and stroke is crucial in reducing health disparities, particularly in historically marginalized and under-resourced communities, as well as communities with high levels of air pollution exposure.

Researchers Link Heart Attack Deaths to Heat Waves and Short-term Air Pollution Exposure

The researchers analyzed 202,678 heart attack...
