Brief Summary:
A prospective post-market study to evaluate the performance and clinic usability of heart failure risk status (HFRS) feature on CareLink.

Condition or disease
Heart Failure

Detailed Description:
Patients with systolic heart failure (HF) implanted with Medtronic wireless implantable cardiac defibrillator (ICD) or cardiac resynchronization therapy device with defibrillation capabilities (CRT-D) devices will be enrolled in the study. The purpose of the study is to evaluate the usability of CareLink HFRS to manage a patient's heart failure.

no treatment
non-randomized, all subjects who have been implanted with an ICD or CRT-D for at least 3 months

Primary Outcome Measures :
  1. Heart Failure Risk Status Performance Characterization [ Time Frame: from baseline until a subject completes 8 months of follow up ]
    The clinical signs and symptoms of worsening HF that are associated with an Heart Failure Risk Status triggered by an OptiVol alert

Secondary Outcome Measures :
  1. Heart Failure Risk Status and medical management [ Time Frame: from baseline for each subject until they complete 8 months of follow up ]
    The correlation between HFRS burden and clinician's assessment of a subject risk and the subject's medical management
