The triglyceride-glucose (TyG) index is significantly associated with short-term mortality in patients with cardiogenic shock (CS) and may serve as a useful biomarker for risk stratification.

This retrospective cohort study analyzed 727 patients with CS from the Medical Information Mart for Intensive Care IV database.

The TyG index was calculated as follows: ln[triglycerides (mg/dL) × fasting blood glucose (mg/dL)/2].

Outcomes included 28-day intensive care unit (ICU) mortality and 28-day in-hospital mortality.

Kaplan-Meier survival curve models and Cox proportional hazards regression models were used to evaluate the prognostic significance of the TyG index.

Receiver Operating Characteristic (ROC) curve analysis was used to determine the predictive efficacy of the TyG index for mortality.

Subgroup analyses were conducted to determine the association between the TyG index and mortality across different groups.
