The potential of triglyceride-glucose index in improving the prediction of post-percutaneous coronary intervention clinical outcomes: a systematic review and meta-analysis

Introduction Despite percutaneous coronary intervention is the current preferred reperfusion modality, the incidence of major adverse cardiovascular events (MACE) is still high. Currently, GRACE score is used for predicting PCI outcomes. The TyG (triglyceride-glucose) index, a potential predictor based on insulin resistance of cardiovascular disease, has not been considered in the GRACE score.
