Ambient Air Pollution Exposure and Adverse Outcomes Among Medicare Beneficiaries With Heart Failure.

ABSTRACT:

Background

Exposure to fine particulate matter (<2.5 um, particulate matter with an aerodynamic diameter <2.5 microns [PM_2.5]) has been implicated in atherogenesis. Limited data in animal studies suggest that PM_2.5 exposure leads to myocardial fibrosis and increased incidence of heart failure (HF). Whether PM_2.5 is associated with adverse outcomes in patients with preexisting HF has not been widely studied.

Methods and results

In this retrospective cohort study, Medicare patients hospitalized with first HF between 2013 and 2020 were identified from the Medicare Provider Analysis and Review Part A 100% files. Patients were linked with integrated estimates of ambient PM_2.5 obtained at 1×1 km using the zip code of participants' reside
