Relationship among body mass index, NT-proBNP, and mortality in decompensated chronic heart failure
BACKGROUND:
Obesity has been suggested to confer a survival benefit in acute heart failure. The concentrations of NT-proBNP may be reduced in patients with high body mass index (BMI).
OBJECTIVES:
To investigate the relationship among BMI, NT-proBNP, and mortality risk in decompensated chronic heart failure (DCHF).
METHODS:
This was a retrospective study. We studied 1001 patients with DCHF. Hazard ratios (HR) were calculated with Cox regression analysis.
