Correlation between triglyceride-glucose index and in-hospital cardiogenic shock in non-diabetic patients with ST-segment elevation myocardial infarction undergoing direct PCI
Objective To analyze the correlation between triglyceride-glucose(TyG)index and in-hospital cardiogenic shock(CS)in non-diabetic patients with ST-segment elevation myocardial infarction(STEMI)undergoing direct percutaneous coronary intervention(PCI).Methods The clinical data of 839 non-diabetic STEMI patients who received direct PCI in the First People's Hospital of Changzhou from January 2017 to July 2022 were retrospectively analyzed.According to the tertile of TyG index,the patients were divided into Q1 group,Q2 group and Q3 group.The influencing factors of CS in non-diabetic STEMI patients treated with direct PCI were analyzed.Results According to the tertile of TyG index,280 cases were included in the Q1 group,279 cases in the Q2 group and 280 cases in the Q3 group.Spearman correlation analysis showed that TyG index was positively correlated with the occurrence of CS(P<0.05).Multivariate Logistic regression analysis showed that TyG index,neutrophil ratio,platelet count,creatinine and left ventricular ejection fraction(LVEF)were independent influencing factors of CS in non-diabetic STEMI patients treated with direct PCI(P<0.05).The receiver operating characteristic(ROC)curve showed that the areas under curve(AUC)of TyG index for predicting CS was 0.614,the sensitivity was 52.5%,and the specificity was 67.6%.Conclusion High TyG index is associated with in-hospital CS in non-diabetic STEMI patients undergoing direct PCI.
