Independent prognostic value of the triglyceride–glucose index and its incremental predictive contribution beyond traditional risk markers in acute heart failure: a retrospective cohort study
Prognostic Significance of the Triglyceride–Glucose Index in Acute Heart Failure
Overview
This study evaluates the prognostic value of the triglyceride–glucose (TyG) index in patients hospitalized with acute heart failure. Higher TyG levels are independently associated with increased risks of cardiovascular death or rehospitalization, suggesting that TyG may enhance risk stratification beyond conventional biomarkers like NT-proBNP.
Background
Acute heart failure is a leading cause of hospitalization and mortality, with significant challenges in risk stratification. Traditional biomarkers such as NT-proBNP have variable predictive performance, highlighting the need for additional markers. The TyG index, a marker of insulin resistance, has shown associations with adverse cardiovascular outcomes, warranting investigation into its prognostic relevance in acute heart failure.

Measure
Value
Composite endpoint events
184
Hazard Ratio for TyG (fully adjusted)
1.74 (95% CI: 1.35–2.25, P < 0.001)
Hazard Ratio for highest TyG quartile
2.17 (95% CI: 1.34–3.50)
TyG threshold for nonlinear association
9.659
Key Findings
Higher TyG levels correlate with increased risk of cardiovascular death or rehospitalization.
TyG index provides prognostic information comparable to NT-proBNP.
Patients in the highest TyG quartile have a significantly elevated risk compared to those in the lowest quartile.
Nonlinear association between TyG and outcomes identified a threshold at 9.659.
Combined models of TyG and NT-proBNP improve risk prediction capabilities.
Clinical Implications
The TyG index can serve as a valuable adjunct in the risk stratification of patients with acute heart failure, potentially guiding clinical decision-making. Incorporating TyG into existing prognostic models may enhance the identification of high-risk patients, allowing for more targeted interventions.
Conclusion
The triglyceride–glucose index is a significant prognostic marker in acute heart failure, independently associated with adverse outcomes. Its integration into clinical practice may improve risk assessment and management strategies for affected patients.
