Wildland Fire-Related Smoke PM2.5 and Cardiovascular Disease ED Visits in the Western United States (Updated October 15, 2024).

The article explores the impact of short-term exposure to fine particulate matter (PM2.5) from wildland fire smoke on cardiovascular disease (CVD) in the Western United States from 2007 to 2018. The study analyzed Emergency Department (ED) visits for atrial fibrillation, acute myocardial infarction, heart failure, stroke, and total CVD, finding a slight decrease in risk for AF, HF, and CVD with a 10 ug/m3 increase in smoke PM2.5. However, further investigation is needed to understand the reasons behind these unexpected findings. [Extracted from the article]
