A Phenomapping Tool and Clinical Score to Identify Low Diuretic Efficiency in Acute Decompensated Heart Failure

JACC Heart FailPublished

  • Prognostic model development and validation study
  • machine learning-based phenomapping
  • external validation
  • pooled acute decompensated heart failure (ADHF) trials

Authors' conclusion

The authors developed and validated a phenomapping strategy and diuresis score for individuals with ADHF and differential response to diuretic therapy, which was associated with length of stay and mortality.

Study context

Population
Patients with acute decompensated HF from pooled trials (derivation ROSE-AHF, CARRESS-HF, ATHENA-HF; validation DOSE/ESCAPE)derivation cohort
Participants
794 patients
Comparison
Diuretic efficiency phenogroups; BAN-ADHF score
  • Phenogroup 1n = 370
  • Phenogroup 2n = 290
  • Phenogroup 3n = 134reference
Outcome
Diuretic efficiency (urine output over first 72 h per total IV furosemide-equivalent loop diuretic dose)
Follow-up
First 72 hours

Performance

As reported in the abstract

Diuretic efficiency by phenogroup

BAN-ADHF score prediction of lowest diuretic efficiency phenogroup

C-index (DOSE/ESCAPE validation cohort)
0.92
Superior to creatinine, blood urea nitrogen, natriuretic peptides or home diuretic dose (DeLong)
P < 0.001

Net urine output with 80 mg IV twice-daily furosemide, BAN-ADHF score 5 vs 20 · 24 hours

mL per 24 hours

Low (5) BAN-ADHF score
2,650
High (20) BAN-ADHF score
660

Higher BAN-ADHF score and clinical outcomes

Significantly lower global well-being, higher discharge natriuretic peptides, longer in-hospital stay and higher in-hospital mortality risk in derivation and validation cohorts
