Key result
Only robust decreases (>80%) in BNP concentrations were associated with a reduced risk of heart failure hospitalization (HR 0.318, P=0.0315) in outpatients with chronic heart failure.
Why the study?
Does the magnitude of change in BNP and NT-proBNP concentrations predict outcomes in ambulatory patients with chronic heart failure?
Cohort (n=172)

Effect estimate: HR 0.318
p-value: p=0.0315
Only large reductions (>80%) in natriuretic peptide concentrations or crossing specific cutpoints are associated with reduced risk of adverse events in chronic heart failure patients.

Robust BNP reductions associate with lower HF hospitalization risk in chronic HF outpatients; leaves open whether serial NP monitoring improves outcomes.
Miller et al. (2008) conducted a cohort in chronic heart failure (n=172). Serial measurements of natriuretic peptides (BNP and NT-proBNP) vs. No change (<20% increase or decrease) was evaluated on death/transplantation or heart failure hospitalization (HR 0.318, p=0.0315). Only robust decreases (>80%) in BNP concentrations were associated with a reduced risk of heart failure hospitalization (HR 0.318, P=0.0315) in outpatients with chronic heart failure.
