Optimization of the use of B-type natriuretic peptide levels for risk stratification at discharge in elderly patients with decompensated heart failure

Predischarge BNP and inhospital BNP change should not be interpreted independently from each other. The highest risk group includes patients with a high predischarge BNP level corresponding to more than the half of the BNP on admission. These patients would benefit from close monitoring for signs of decompensation.
