Does Lung Impedance Correlate With Changes in BNP in Stable and Acutely Decompensated Heart Failure Patients? — IMPEDE-HF  

Congestive Heart Failure Clinical Trial

Official title:
Does Lung Impedance Correlate With Changes in BNP in Stable and Acutely Decompensated Heart Failure Patients?

Clinical Trial Summary

The purpose of this study is to determine whether there is a relationship between serial B-natriuretic peptide (BNP) and implantable device measured intrathoracic impedance in symptomatic and asymptomatic heart failure patients over a 1-year period. Furthermore, this study will establish whether implantable device measured intrathoracic impedance trends with the distance walked on a six-minute hall walk (6MHW), an exercise-based acute measure that has also been associated with heart failure clinical status.

Clinical Trial Description

This is a prospective non-randomized longitudinal study. One hundred subjects will participate in 6 monthly and 3 bi-monthly serial assessments of plasma-based BNP, implantable device measured intrathoracic impedance, and clinical evaluation of heart failure status. Each patient will be enrolled in the study for a period of 12 months. ;
