Brief Summary:

The objective of this study is to compare two different strategies of disease management in heart failure patients treated with cardiac resynchronization therapy devices

  1. Remote monitoring with CareLink Network System
  2. Standard management of the disease by means of scheduled routine in-patient follow-ups;

and to demonstrate that the remote monitoring strategy is superior to the standard strategy, both in terms of clinical effectiveness and total healthcare system utilization.

Arm Intervention/treatment
Active Comparator: Study Group
Patients of the study arm are CRT-D patients followed-up by means of a remote disease management system (Medtronic Carelink® Network), for which an automatic alerting system is enabled for fluid accumulation, AT/AF episodes and system integrity.
Device: Medtronic CareLink® Network

Continuous monitoring via a disease remote management system.

Patients of the Study group will receive a remote monitor and their device will be programmed to have wireless telemetry, Care Alerts, and the ability to transmit over the Medtronic CareLink® network. Clinical and device conditions will be then monitored continuously and alarms for the physician will be generated if a set of pre-defined potentially harming conditions should occur.

No Intervention: Control Group
Patients are CRT-D patients managed according to current standard clinical practice, based on routinely performed in-office visits.

Primary Outcome Measures :
  1. Phase 1: Median Time Between Event Onset Time and Clinical Decision for Each Subject. [ Time Frame: 1 year since the randomization ]
    The median delay from device-detected events to clinical decisions was considerably shorter in the Remote group compared to the Control group

  2. Phase 2: Combined Endpoint of Death From Any Cause, Cardiovascular and Device-related Hospitalizations (at Least 48 Hours Stay), Calculated as Number of Subjects With at Least One Event [ Time Frame: 2 years after randomization ]
    Time to first event
