Feasibility Study of an Integrated Diagnostic System to Manage Heart Failure (INDICATE HF)

April 13, 2012 updated by: Medtronic Cardiac Rhythm and Heart Failure

Integrated Diagnostics Can Alter Heart Failure

The purpose of this clinical trial is to evaluate the potential benefits of a new heart failure diagnostic system for heart failure patients with implanted cardiac resynchronization therapy devices. This system consists of patient tools, a new heart failure risk score and a new clinician website. This study will evaluate this new system as a whole and establish the feasibility of implementing it into clinical practice.

How is the study designed?

Design Details

  • Primary Purpose: Diagnostic
  • Allocation: Randomized
  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Active Comparator: Control Arm
Other: Routine in office visits
Heart failure will be managed with scheduled in-office visits every three months.
Experimental: Integrated Diagnostics Arm
Other: Integrated diagnositic system
Heart failure will be managed using the integrated diagnostic system which consists of patient tools and a new Heart Failure Clinician's website which displays a new Heart Failure Risk score. This Heart Failure Clinician's website will be reviewed every 2 weeks in addition to scheduled in-office visits every three months.
