In patients with coronary heart disease, a higher estimated glucose disposal rate (eGDR) is strongly associated with a reduced risk of incident heart failure, with predictive changes detectable up to 15 years prior to diagnosis.
BACKGROUND: Estimated glucose disposal rate (eGDR) is a composite index of insulin resistance (IR). However, its association with incident heart failure (HF) in coronary heart disease (CHD) patients remains unknown. METHODS: This prospective cohort study included 20,329 CHD patients from the UK Biobank. Baseline eGDR and several IR indices were calculated. Associations between eGDR, IR indices and incident HF were assessed separately based on Cox regression models. Also, receiver operating characteristic (ROC) analyses were conducted to evaluate the performance of the eGDR and other IR index in predicting the 10-year risk of HF. Finally, we specifically analyzed the temporal trajectory of eGDR levels in the 15 years leading up to HF onset based on time trajectory curves. RESULTS: 3364 participants developed incident HF over the follow-up. eGDR demonstrated superior risk stratification ability compared to other IR indices. Specifically, each 1-unit increase was associated with a 51% reduction in risk (HR = 0.49, 95% CI 0.38-0.64). Furthermore, eGDR exhibited the highest discriminative ability for participants at high risk of HF among all insulin resistance indices (AUC = 0.612, 95% CI 0.601-0.623). Trajectory analysis revealed that eGDR levels in individuals who eventually developed HF remained at a low level starting 15 years prior to the onset of HF. CONCLUSION: eGDR is closely linked to HF risk in the CHD population and exhibits stronger predictive power than other IR indices. Notably, eGDR levels change up to 15 years before the occurrence of HF, suggesting that eGDR could serve as an early predictor for HF among CHD patients.

Xu et al. (2026) conducted a cohort in Coronary heart disease (n=20,329). Estimated glucose disposal rate (eGDR) vs. Lower eGDR levels was evaluated on Incident heart failure (HR 0.49, 95% CI 0.38-0.64). Each 1-unit increase in estimated glucose disposal rate was associated with a 51% reduction in the risk of incident heart failure among patients with coronary heart disease (HR 0.49).
