Triglyceride index as a predictor of mortality after cardiac surgery.

ABSTRACT: The triglyceride-glucose (TyG) index, a marker for insulin resistance, has been linked to adverse cardiac outcomes. Its role in predicting mortality following cardiac surgery remains unclear. This study analyzed 1,810 cardiac surgery patients from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database, categorized by TyG index levels. Mortality was the primary outcome, assessed through Cox proportional hazards regression, time-dependent receiver operating characteristic (ROC) analysis, and restricted cubic splines. Over a 13-year follow-up, 83 patients died. Higher TyG index levels were associated with increased mortality risk (hazard ratio [HR] = 1.206, 95% confidence interval [CI], 1.121-1.297, p < 0.001). Time-dependent ROC analysis showed areas under the curve (AUCs) of
