Heart failure & cardiomyopathiesMeta-analysis

Obesity and Risk of Kidney Outcomes in Heart Failure With Preserved Ejection Fraction

JACC Heart FailPublished

  • Participant-level pooled analysis of 4 heart failure with preserved ejection fraction (HFpEF) randomised trials
  • multivariable Cox models stratified by trial and treatment

Authors' conclusion

WC and WHtR were associated with an increased risk of kidney outcomes, while BMI was not.

Study context

Population
Patients with HFpEF in DELIVER, PARAGON-HF, TOPCAT Americas and I-PRESERVE

Comparison
Adiposity-related anthropometrics and kidney outcomes
Outcome
Kidney outcomes:
  • Sustained eGFR reduction ≥50%
  • End-stage kidney disease
  • Kidney-related death
