Heart failure & cardiomyopathiesCohort study

Type 2 diabetes and chronic kidney disease combinations in heart failure across the ejection fraction spectrum: clinical associations, medication use, and cause-specific outcomes: a contemporary, real-world analysis of the Swedish Heart Failure Registry

Eur J Heart FailPublished

  • Registry-based cohort study
  • Swedish heart failure (HF) registry
  • 2017-2023

Authors' conclusion

CKD was more common in HFpEF and a strong independent risk factor for all outcomes. T2DM was a moderate independent risk factor for all outcomes.

Study context

Population
Patients with HF across the EF spectrum in the Swedish HF registry, 2017–202334% females, mean age 73 years
Participants
54,341 patients
Exposure
Chronic kidney disease (CKD) and T2DM combinations in HF

Main finding

As reported in the abstract

Prevalence of CKD/T2DM combinations

Observational data: associations, not effects.

Further findings

Prevalence by EF category (CKD only; CKD/T2DM)

HF with preserved ejection fraction (HFpEF)
29% and 15%
HFmrEF
23% and 11%
HFrEF
22% and 10%

HF medication use

Generally lower in groups with CKD, especially MRA

End-stage renal disease (ESRD)

T2DM alone did not significantly increase risk
CKD alone increased risk threefold
Both CKD and T2DM increased risk six-fold

Risk by EF category

CKD added more to the risk of events in HFrEF than in HFpEF
