Overview

Nationwide prospective cohort study finds TyG-Frailty Index predicts CVD and mortality in those with cardiovascular-kidney-metabolic syndrome stages 0-3, suggesting clinical relevance.

Key Points

  • This study aims to evaluate the association between the Triglyceride-Glucose-Frailty Index (TyGFI) and the incidence of cardiovascular disease (CVD) and all-cause mortality in individuals with cardiovascular-kidney-metabolic syndrome stages 0-3.
  • Included 6207 individuals for CVD and 6386 for all-cause mortality from the China Health and Retirement Longitudinal Study.
  • Analyzed data using multivariable Cox proportional hazards models, Kaplan–Meier curves, ROC curves, and mediation analysis.
  • Conducted subgroup analyses to evaluate differing sociodemographic and clinical characteristics.
  • TyGFI significantly associated with increased CVD risk (HR = 1.25, 95% CI: 1.18–1.33) and all-cause mortality (HR = 1.39, 95% CI: 1.18–1.63).
  • Highest TyGFI quartile faced increased CVD risk (HR = 2.02, 95% CI: 1.69–2.42) and mortality (HR = 2.67, 95% CI: 1.33–5.38) compared to the lowest quartile.
  • Age mediates the effect of TyGFI on CVD (mediation proportion = 9.81%) and mortality (mediation proportion = 32.45%).
