Long-term exposure to PM_2.5 components and cardiovascular admissions in medicare patients.

ABSTRACT:

Background

Fine particulate matter (PM_2.5) has been previously linked to cardiovascular diseases (CVDs). PM_2.5 is a mixture of components, each of which has its own toxicity profile which are not yet well understood. This study explores the relationship between long-term exposure to PM_2.5 components and hospital admissions with CVDs in the Medicare population.

Methods

We analyzed data from U.S. Medicare fee-for-service beneficiaries between 2000 and 2016. Annual levels of fifteen PM_2.5 components were derived from hyperlocal spatiotemporal models. Our outcomes included hospital admissions with CVDs, and more specifically with myocardial infarction, ischemic stroke, atrial fibrillation, and heart failure. A weighted quantile sum (WQ
