Association Between Ambient Temperature and Myocardial Injury After Noncardiac Surgery in Adults: a Retrospective Single-center Cohort Study

This single-center retrospective cohort study enrolled patients aged ≥18 years who underwent noncardiac surgery between January 2014 and December 2023. The exposure variable was the 7-day average preoperative ambient temperature in Beijing. Univariate and multivariate logistic regression models were used to evaluate the association between temperature and MINS. Inverse probability of treatment weighting (IPTW) analysis was performed to enhance the robustness of the findings. Subgroup analyses were performed across predefined clinical strata.
