The aim of this study was to investigate the relationship between baseline TyG index and no-reflow phenomenon in STEMI patients with T2DM after PCI.This study enrolled 695 patients with T2DM and STEMI from the General Hospital of Ningxia Medical University (2014)(2015)(2016)(2017)(2018)(2019). Patients were divided into tertiles according to the TyG index levels. The incidence of no-reflow phenomenon was recorded. A multivariate regression model was developed to analyze the association between baseline TyG index and no-reflow phenomenon. The linear association between baseline TyG index and no-reflow phenomenon was explored using smooth curve fitting with parallel subgroup analyses. Receiver operating characteristic (ROC) curve were generated to determine predictive power of TyG index.A multivariate logistic regression model revealed that the TyG index was an independent risk factor of no-reflow phenomenon [OR=3.23,95%CI: 2.15-4.86, P<0.001], and the occurrence of no-reflow phenomenon increased gradually with the increase of TyG index tertile interval (P < 0.001). Smooth curve fitting showed that TyG index was linearly related to the risk of no-reflow. Subgroup analysis showed that they participated in this positive correlation. The area under ROC curve (AUC) of the TyG index for evaluating the occurrence of No-reflow was 0.710 (95% CI 0.640-0.780; p<0.01).Conclusions TyG index is independently associated with no-reflow phenomenon, suggesting that the simple index of TyG index can be used for risk assessment of no-reflow phenomenon after PCI in STEMI patients with T2DM.
