Effects of intermediate and long-term exposure to ambient air pollution and temperature on hospital admissions with second cardiovascular events among medicare beneficiaries.

ABSTRACT:

Background

Air pollution has been linked to cardiovascular diseases (CVDs). In this study, we assess whether exposure to air pollutants and ambient temperature is associated with repeated admissions with adverse cardiovascular outcomes.

Methods

We used data from Medicare beneficiaries between 2000 and 2016 to look at the effects of intermediate and long-term exposure to ambient PM_2.5, NO₂, O₃, and temperature on second admissions with myocardial infarction (MI) and ischemic stroke. We derived exposure levels from high-resolution spatiotemporal models. We adjusted for demographic, socioeconomic, and access-to-care characteristics. Cox proportional hazards models were used to assess these relationships. We further looked at the effects of expos
