Brief Summary:
This chronic, prospective, non-randomized feasibility study is designed to evaluate the Integrated Patient Care (IPC) concept in subjects who already have either a Medtronic Chronicle Implantable Hemodynamic Monitor (IHM) or Chronicle Implantable Cardioverter Defibrillator (ICD) device implanted, and are currently enrolled in the Chronicle Offers Management to Patients with Advanced Signs & Symptoms of Heart Failure (COMPASS-HF) Extension Phase Study (IDE # G020304). The purpose of the study is to use daily cardiac filling pressures from the Chronicle device to provide timely medication adjustments (diuretics) to subjects.

Condition or disease Intervention/treatment Phase
Heart Failure Drug: Diuretics Phase 2

Detailed Description:

Subjects will be asked to transmit to the CareLink Network daily. Data specific to this study (subject's daily estimated Pulmonary Arterial Diastolic (ePAD) pressure values) will be extracted from the CareLink database and transferred to the IPC clinician website.

As each subject is enrolled, clinicians at each participating site will determine the appropriate target pressure range for each subject based on a review of the subject's pressure data. Each day after enrollment, the subject's current pressure data will be compared to a target pressure range that the clinician sets for that subject.

The patient instruction set (PtIS) is limited to a daily diuretic prescription and associated supplements, per physician discretion. The PtIS should not include adjustments of non-heart failure medications and should not include heart failure medications that are not indicated for day-to-day adjustments (e.g. ACE-Inhibitors, Angiotensin Receptor Blockers (ARBs), and Beta-Blockers). The PtIS will be sent from the IPC clinician website to the subject through a Patient Home Monitor.

Primary Outcome Measures :
  1. Characterize the technical feasibility of the network based IPC system [ Time Frame: Baseline through Completion/Exit ]
    The proportion of study days that the delivered PtIS is based on the subjects' daily pressure state will be summarized.

Secondary Outcome Measures :
  1. Characterize the rate of IPC setup system changes [ Time Frame: Baseline through Completion/Exit ]
    The frequency and reason for changes in the IPC setup will be documented and summarized.

  2. Quantify subject compliance to daily PtIS [ Time Frame: Baseline through Completion/Exit ]
    The frequency of patient use and compliance with the daily IPC system will be summarized.

  3. Estimate changes in clinical markers of heart failure and kidney function [ Time Frame: Baseline through Completion/Exit ]
    Changes in laboratory measurements (BNP, BUN, eGFR, etc.) and ePAD will be summarized.

  4. Summarize adverse events [ Time Frame: Baseline through Completion/Exit ]
    All serious adverse events, cardiovascular adverse events, and event related to the IPC system will be documented and summarized.
