Triglyceride–Glucose Index as a Predictor of Major Adverse Cardiovascular Events in Post-PCI Patients Diagnosed with In-Stent Restenosis

The triglyceride-glucose index (TyG) is a reliable indicator for predicting the prognosis of patients with coronary heart disease (CAD) after percutaneous coronary intervention (PCI). However, its influence on patients with in-stent restenosis (ISR) is unclear. This study was designed to evaluate the association between the TyG index and the occurrence of major adverse cardiovascular events (MACEs) after PCI in patients with ISR.
