Authors' conclusion

The same NT-proBNP concentration predicts a substantially higher absolute risk of adverse outcomes for people with heart failure and reduced kidney function, compared with those with preserved kidney function.

Study context

Population
Patients with HF and mildly reduced or preserved EF with baseline NT-proBNP and estimated glomerular filtration rate (eGFR)3,092 primary outcomes
Participants
14,831 patients
Comparison
NT-proBNP and outcomes across eGFR categories
Outcome
HF hospitalization or CV death
Follow-up
Median 33.5 months

Pooled result

Primary outcome per doubling of NT-proBNP

Hazard ratio

1.37

95% CI 1.34–1.41

Each doubling in NT-proBNP
HR 1.37 (95% CI 1.34–1.41)

Each doubling in NT-proBNP, as printed

As reported in the abstract

Further pooled results

NT-proBNP increase per 10 mL/min/1.73 m² lower eGFR

  • NT-proBNP increase per 10 mL/min/1.73 m² lower eGFR: P for nonlinearity < 0.001

All outcomes studied, incl. CV and non-CV death

Similar patterns observed
