Correlation analysis between hospital admission risk and air pollutants in patients with acute coronary syndrome in Hefei City from 2015-2021

Abstract

Abstract: Objective To explore the association between the concentrations of fine particulate matter（PM_2.5）,inhalable particulate matter（PM₁₀）,sulfur dioxide（SO₂）,carbon monoxide（CO）,nitrogen dioxide（NO₂） and ozone 8 h（O_3-8h） in Hefei and the risk of hospital admission in patients with acute coronary syndrome（ACS）. Methods The admission data（gender,age,the days of hospitalization,and hospitalization costs） of 3 475 ACS patients who were admitted to agrade-A tertiary hospital in Hefei City and air pollutant indicators were collected from March 2015 to December 2021. The Spearman method was used to analyze their correlation. Results The number of admissions of ACS patients was positively correlated with PM₁₀ and NO₂（all P<0.05）.The days of hospitalization were positively correlated with CO（P<0.05）. The hospitalization costs were positively correlated with PM₁₀ and SO₂（all P<0.05）. The number of admissions of male patients was positively correlated with PM₁₀,PM_2.5,SO₂ and NO₂ in autumn（all P<0.05）.The number of admissions of male patients was positively correlated with PM₁₀,SO₂ and NO₂ in winter（all P<0.05）. Conclusion The PM₁₀ and NO₂ are the most important pollutants that increase the admission risk of ACS patients in Hefei City,males are potentially susceptible in autumn and winter,and air pollution can both increase the per capita hospitalization burden and the overall hospitalization burden of ACS patients.
