Abstract：Objective To compare the predictive value of triglyceride-glucose index(TyG index)and atherogenic index of plasma(AIP)for in-hospital major adverse cardiovascular events(MACE)in patients with acute myocardial infarction(AMI)undergoing emergency percutaneous coronary intervention(PCI).Methods This was a multicenter retrospective study.A total of 603 AMI patients who underwent emergency PCI were enrolled.According to the occurrence of in-hospital MACE,the patients were divided into MACE group(n=524)and non-MACE group(n=79).Baseline data,laboratory indicators and clinical outcomes were collected from all patients.The association between TyG index/AIP and in-hospital MACE was evaluated by using multivariate Logistic regression analysis,and the predictive efficacy of the two indices was compared by using receiver operating characteristic(ROC)curves.Results Both TyG index and AIP were significantly higher in MACE group than those in non-MACE group(P<0.05).the results of multivariate analysis showed that TyG index(OR=2.655,95%CI:1.578～4.467)and AIP(OR=7.809,95%CI:2.562～23.803)were independent predictors of in-hospital MACE.The results of ROC curve analysis indicated that the area under the curve(AUC)of TyG index was 0.638,which was superior to that of AIP(0.581,P=0.031).Conclusion Both TyG index and AIP can serve as independent predictors for in-hospital MACE in AMI patients after emergency PCI.Among them,TyG index has slightly better predictive efficacy than AIP and thus holds greater potential for clinical application.
