Wildland Fire-Related Smoke PM_2.5 and Cardiovascular Disease Emergency Department Visits in the Western United States.

ABSTRACT:

Background

The impact of short-term exposure to fine particulate matter with a diameter ≤2.5 μm (PM_2.5) due to wildland fire smoke on the risk of cardiovascular disease (CVD) remains unclear. We investigated the association between short-term exposure to wildfire smoke PM_2.5 and emergency department visits for acute CVD in the western United States from 2007 to 2018.

Methods

We analyzed 49 759 958 emergency department visits for primary or secondary diagnoses of atrial fibrillation (AF), acute myocardial infarction, heart failure, stroke, and total CVD across 5 states. Daily smoke, nonsmoke, and total PM_2.5 were estimated using a 1-km resolution satellite-driven multistage model and were aggregated to the zip code level. A case-crossover stud
