Key result
Higher stress hyperglycemia ratio is linked to ~35% higher 180-day mortality in critically ill HF.
Why the study?
It was unclear whether stress-induced hyperglycemia ratio or triglyceride-glucose index has superior association and predictive value for prognosis in critically ill patients with heart failure.
Does stress hyperglycemia ratio (SHR) or triglyceride-glucose (TyG) index better predict mortality in critically ill heart failure patients?

Does stress hyperglycemia ratio (SHR) or triglyceride-glucose (TyG) index better predict mortality in critically ill heart failure patients?
Hazard Ratio: 1.35 (95% CI 1.12–1.64)
p-value: p=0.002
SHR and TyG index can both assess short-term mortality risk in critically ill HF patients, but SHR is a more robust biomarker for predicting 1-year mortality.
Background Heart failure (HF) is a life-threatening clinical syndrome characterized by high incidence and mortality, leading to considerable global health and economic burdens. Stress-induced hyperglycemia ratio (SHR) and triglyceride-glucose (TyG) index, as emerging biomarkers reflecting glucose metabolism, are closely associated with poor prognosis in many diseases. However, it remains unclear which of these two indicators possesses superior association and predictive value for prognosis in critically ill patients with HF. Methods A retrospective cohort study was conducted on critically ill HF patients, enrolled from the Medical Information Mart for Intensive Care IV (MIMIC-IV) version 3.1. The primary outcome was 180-day mortality, with 1-year (365-day), 90-day, and 30-day mortality as secondary outcomes. Baseline characteristics were compared between survivors and non-survivors. Cox regression, restricted cubic spline (RCS), Kaplan-Meier (K-M), and subgroup analyses were used to assess the association of SHR and TyG index with mortality. Discriminative performance of SHR versus TyG index was compared using ROC curves. Results A total of 1,063 patients were enrolled. After adjusting for confounders, Cox regression analyses revealed that SHR was significantly associated with an increased risk of 180-day, 365-day, 90-day, and 30-day mortality, with hazard ratios (HRs) of 1.35, 1.26, 1.47, and 1.53, respectively. In contrast, TyG index was only associated with mortality risk at 180, 90, and 30 days (HRs: 1.20, 1.24, and 1.31, respectively), with no significant association observed at 1 year. Moreover, these associations were predominantly linear in nature. However, no statistically significant difference was observed in the predictive performance of SHR and TyG index for mortality at any time points ( P >0.05). Conclusion SHR and TyG index can be used as potential risk assessment tools for short-term (180-, 90-, and 30-day) mortality risk in critically ill HF patients, nevertheless, SHR is a more applicable and robust metabolic biomarker associated with 1-year mortality.

Song et al. (2026) conducted a cohort in Heart failure (n=1,063). Stress hyperglycemia ratio (SHR) vs. Lower SHR levels was evaluated on 180-day mortality (HR 1.35, 95% CI 1.12-1.64, p=0.002). Higher stress hyperglycemia ratio was significantly associated with an increased risk of 180-day mortality (HR 1.35) in critically ill patients with heart failure.
