Predictive value for death and rehospitalization of 30-day postdischarge B-type natriuretic peptide (BNP) in elderly patients with heart failure. Sub-analysis of Italian RED Study

摘要

Background: Our aim was to determine if, in elderly heart failure (eHF) patients, serial B-type natriuretic peptide (BNP) assessments obtained during follow-up after hospital discharge could have prognostic utility for death and rehospitalizations. In eHF patients, BNP assessment at hospital discharge has been demonstrated to have a high prognostic value; however, its predictive role for future cardiovascular events in eHF patients, when assessed in the period after discharge, both for the correct timing and cut-off levels, has not been completely elucidated.
