Brief Summary:
Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. Using very low electrical pulses that travel across the inside of the chest cavity, thoracic fluid status monitoring (OptiVol™) can measure the level of resistance to the electrical pulses, which indicates the level of fluid in the chest. The purpose of this study is to collect information related to fluid build up in the chest of subjects with heart failure.

Intervention Details:
  • Device: Fluid Status Monitoring (OptiVol™)
    Thoracic Fluid Status Software downloaded on all subjects enrolled in the trial

Primary Outcome Measures :
  1. Number of Subjects With at Least 30 Days of Daily Impedance Measurements [ Time Frame: Up to 36 months. ]
    Impedance measurements were presented graphically over time in relation to clinical events for all subjects with at least 30 days of follow-up and impedance data collected during the follow-up period.

Secondary Outcome Measures :
  1. Change in Thoracic Impedance Associated With Heart Failure (HF) Hospitalization for an Exacerbation of HF [ Time Frame: 3 days pre-admission and 3 days post-discharge ]
    Difference in mean thoracic impedance: post-hospitalization minus pre-hospitalization.

  2. Change in Thoracic Impedance Associated With Heart Failure (HF) Outpatient Treatment of an Exacerbation of HF [ Time Frame: 1 day pre and 1 day post-outpatient visit ]
    Difference in mean thoracic impedance: post-outpatient visit minus pre-outpatient visit.

  3. Number of Adverse Events [ Time Frame: From enrollment to study exit (up to 36 months). ]
    All adverse events were collected for this trial such as (but not limited to): Atrial Fibrillation, Chest Pain, Pneumonia, Cold/Flu
