The triglyceride-glucose (TyG) index independently predicted severe coronary artery disease in patients with non–ST-segment elevation myocardial infarction. In a dual-centre study of 596 patients, a TyG threshold of 7.39 identified those with left main or three-vessel disease and higher SYNTAX scores. Prediction improved when TyG was combined with age and ST-segment elevation in lead aVR. Researchers noted the retrospective design, modest sample size, and incomplete medication histories as study limitations.
