Ambient fine particulate matter chemical composition associated with in-hospital case fatality, hospital expenses, and length of hospital stay among patients with heart failure in China.

ABSTRACT: *Joint senior authorship.

Background

Previous studies have observed the adverse effects of ambient fine particulate matter pollution (PM_2.5) on heart failure (HF). However, evidence regarding the impacts of specific PM_2.5 components remains scarce.

Methods

We included 58 129 patients hospitalised for HF between 2013 and 2017 in 11 cities of Shanxi, China from inpatient discharge database. We evaluated exposure to PM_2.5 and its components ((sulphate (SO₄^2-), nitrate (NO₃^-), ammonium (NH₄⁺), organic matter (OM) and black carbon (BC)), along with meteorological factors using bilinear interpolation at each patients' residential address. We used multivariable logistic and linear regr
