Impact of short-term exposure to ambient air pollution on cardiovascular disease outpatient visits: a time-series study in Yichang, China.

ABSTRACT:

Background

Rapid industrialization has exacerbated ambient air pollution in Yichang, China, posing cardiovascular health risks. This study evaluates the short-term impact of ambient air pollutants on cardiovascular disease (CVD) outpatient visits and assesses the effectiveness of environmental policies implemented post-2018.

Methods

We analyzed 510,831 CVD outpatient records alongside daily concentrations of PM_2.5, PM₁₀, SO₂, NO₂, CO, and O₃ from five monitoring stations. Generalized additive Poisson regression with distributed lag non-linear models (DLNM) quantified associations between ambient air pollutant exposure (per interquartile range (IQR) increase) and daily visits, adjusting for meteorological factors, time tr
