Objective: The purpose of this study was to investigate the correlation between environmental PM2.5 and heart failure (HF) hospitalization in Lanzhou. China. Method: The correlation between atmospheric PM, 5 and HF hospitalization was evaluated using a distributed lag nonlinear model. Result: During the study period, 16,122 HF patients were hospitalized. The average concentration of PM2.5 is 45.24 µg/m³. PM2.5 was positively correlated with HIT hospitalization with single lag (lagO) and cumulative lag (lagO], lag02, lag03). The maximum lag effect is estimated to occur in lag03, and with the PM2.5 concentration increasing by 10 µg/m³, HF hospitalization risk increased by 1.023 (95% confidence interval. 1.006-1.039). The risk of hospitalization for HF in the male group, the age group 65 years or older, and the cold season was statistically significant and more positively correlated. Conclusion: PM2.5 exposure increases the risk of HF admission in Lanzhou. [ABSTRACT FROM AUTHOR]
