Long-term trajectory of estimated glomerular filtration rate in ambulatory patients with type 2 diabetes and heart failure: clinical insights and prognostic implications

Cardiovasc DiabetolPublished Post hoc subanalysis of a prospective registry

Authors' conclusion

This study offers novel insights into long-term renal function trajectories in patients with HF and T2D and identifies key clinical factors associated with accelerated renal decline. Future research is warranted to validate these results in larger, more diverse cohorts and to explore potential therapeutic interventions.

Study context

Population
Ambulatory patients with heart failure (HF) and T2D referred to a specialized HF clinic; mean age 69.3 ± 10.3 years, 68.2% men10,830 creatinine measurements
Participants
1,114 patients
Primary endpoint
Long-term eGFR trajectory (CKD-EPI), assessed at baseline and every three months
Methodological detailssingle specialized HF clinic, longitudinal, multivariable longitudinal Cox regression, Mean 15.8 ± 9.4 creatinine measurements per patient
  • Single specialized HF clinic
  • Longitudinal
  • Multivariable longitudinal Cox regression
  • Mean 15.8 ± 9.4 creatinine measurements per patient

Primary result

As reported in the abstract

Average annual rate of eGFR change

Significant progressive estimated glomerular filtration rate (eGFR) decline; average annual rate (95% CI - 2.11 to - 1.95, p < 0.001)

- 2.05 ml/min/1.73 m²

Further findings

Factors associated with eGFR decline (subgroup analysis)

Older age, nonischaemic HF aetiology, HFpEF or HFmrEF, poor glycaemic control and higher baseline eGFR associated with more pronounced decline in renal function

All-cause mortality

eGFR decrease independently associated with increased risk of all-cause mortality
