Brief 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.

Condition or disease
Congestive Heart Failure

Detailed 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.
