An observational study of Heart Failure, Congestive and Cardiac Pacemaker, Artificial, run by Thomas Jefferson University at 5 sites in United States.
Trial summary
The objective of this study is to evaluate whether the heart rate variability, daily heart rate, and/or intrathoracic impedance recorded by implantable cardiac devices can be used in conjunction with other traditional clinical practice methods to determine if heart failure patients are ready for hospital discharge.

About this study
Official title: Comparing ICD Device Diagnostics to Hospitalized Heart Failure Patient Symptoms and Physician Opinion on Discharge Readiness
The objective of this study is to evaluate whether the heart rate variability, daily heart rate, and/or intrathoracic impedance recorded by implantable cardiac devices can be used in conjunction with other traditional clinical practice methods to determine if heart failure patients are ready for hospital discharge.
Read the detailed description
Implantable cardioverter defibrillator (ICD) devices with or without cardiac resynchronization therapy (CRT-D) have the ability to continuously monitor heart rate variability, daily heart rate, and patient activity. Changes in these measures have been associated with heart failure prognosis. In addition, ICD or CRT-D devices also have the ability to measure daily intrathoracic impedance. Previous data have demonstrated that device-based intrathoracic impedance measurements correlate with pulmonary capillary wedge pressure and fluid retention, both of which are common measures of heart failure status. The objective of this study is to evaluate whether the heart rate variability, daily heart rate, and/or intrathoracic impedance can be used in conjunction with other methods to determine if patients are ready for hospital discharge. This will be the first step in potentially developing an inpatient care strategy which includes implantable device data. It is hypothesized that device diagnostic data will identify an appropriate and safe time to discharge patients admitted for worsening heart failure symptoms before usual clinical indicators. More specifically, we hypothesize that device data will "normalize" at least one day prior to the clinical indicators of readiness for discharge and patients discharged prior to "normalization" of the device data will be at greater risk for rehospitalization

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
The objective of this study is to evaluate whether the heart rate variability, daily heart rate, and/or intrathoracic impedance recorded by implantable cardiac devices can be used in conjunction with other traditional clinical practice methods to determine if heart failure patients are ready for hospital discharge.
