Abstract

Aims: The association of serial NT-proBNP changes and poor quality of life (QOL) with progressive heart failure (HF) and clinical outcomes in emergency department dyspnea patients is poorly understood. Methods and results: The predictive value of changes in NT-proBNP and QOL (Minnesota Living with Heart Failure scale) from baseline to 30-day follow-up was examined for all-cause 1-year mortality and HF hospitalization. Patients with an initially elevated NT-proBNP (≥300. ng/L) which persisted at 30-days (no ≥25% decrease) were at high risk of death or HF hospitalization (HR=6.36, 95%CI =3.04-13.28). Combined with sustained poor QOL, these subjects with persistently elevated NT-proBNP were at highest mortality risk or HF hospitalization (HR=8.75, 95%CI=3.62-21.16). Conclusions: Dyspnea patients with elevated NT-proBNP concentrations and no improvement in either NT-proBNP or QOL at 30-days are at high risk of mortality and HF hospitalization. These data highlight the value of serial biomarker measurements combined with serial evaluations for QOL.
