Association between the triglyceride-glucose index and severe left main and/or three-vessel disease in patients with non-ST-segment elevation myocardial infarction: a dual-centre retrospective study

Patients with NSTEMI demonstrated that a positive relationship was found between a higher level of TyG and an increased level of coronary anatomical complexity (LM/3VD with SYNTAX score >22). The TyG could serve as a non-invasive marker for predicting severe CAD and have implications for guiding treatment strategies in patients with NSTEMI.
