Objective:To analyze the relationship between mC2HEST score and hospitalization outcomes in patients with acute myocardial infarction(AMI)after emergency percutaneous coronary intervention(PCI).Meth-ods:Three hundred and fifty-two patients diagnosed with AMI in the Department of Cardiology at Affiliated Hos-pital of Yunnan University from January 1,2020 to December 31,2021 were enrolled.All patients underwent e-mergency PCI within 24 hours of onset and without preoperative atrial fibrillation.The baseline data and hospital endpoint events,including all-cause death,new-onset atrial fibrillation,cardiogenic shock,cardiac arrest,ische-mic stroke,and bleeding,were collected,and the mC2HEST scores were calculated.The incidence of prognostic events among patients with different mC2HEST scores was compared.The logistic regression analysis was used to explore the relationship between mC2HEST score and prognostic events.The ROC curve was drawn to evaluate the ability of the mC2HEST score,and the Kaplan-Meier survival curve was drawn to evaluate the in-hospital all-cause death.Lastly,we analyzed the differences in the risk of in-hospital all-cause death.Results:The incidence of all-cause death,new-onset atrial fibrillation,cardiogenic shock,and bleeding events increased with the increase of the mC2HEST score.The mC2HEST score was an independent risk factor for all-cause death(OR=3.993),new-onset atrial fibrillation(OR=3.025),cardiogenic shock(OR=1.375),and bleeding(OR=1.334).The mC2HEST score had good predictive value for all-cause death(AUC=0.925)and new-onset atrial fibrillation(AUC=0.832),as well as for cardiogenic shock(AUC=0.700)and bleeding(AUC=0.678).The Kaplan-Meier survival curve suggested that the cumulative risk of in-hospital death in the mC2HEST score high-risk group was significantly higher compared with the intermediate-risk and low-risk groups(P＜0.05).Conclusion:The mC2HEST score is an independent risk factor for all-cause death,new-onset atrial fibrillation,cardiogenic shock,and bleeding during hospitalization in AMI patients after emergency PCI.Compared to low-risk and moderate-risk patients,those with high-risk(mC2HEST score≥5 points)have a significantly increased risk of in-hospital all-cause death.However,the mC2HEST score does not show a correlation with cardiac arrest or stroke.
