REsynchronization reVErses Remodeling in Systolic Left vEntricular Dysfunction (REVERSE) - Study Results

Study Type:	Interventional
Study Design:	Randomized, Double Blind (Subject, Investigator), Active Control, Parallel Assignment
Condition:	Heart Failure
Intervention:	Device: Cardiac Resynchronization Therapy (CRT) Device or Implantable Cardioverter Defibrillator (ICD) with CRT

Participant Flow

Recruitment Details

Key information relevant to the recruitment process for the overall study, such as dates of the recruitment period and locations
Patients were enrolled from September 2004 through September 2006 at 73 sites located in the United States, Canada, and Europe.

Pre-Assignment Details

Significant events and approaches for the overall study following participant enrollment, but prior to group assignment
A total of 684 patients were enrolled in the study. Of these, 642 patients were attempted for cardiac resynchronization therapy (CRT) device implant. 21 were unsuccessful, leaving 621 patients successfully implanted with a CRT device. Of these 621 patients, 610 were randomized.

Reporting Groups

	Description
CRT OFF	Cardiac Resynchronization Therapy (CRT) turned OFF in conjunction with optimal medical therapy
CRT ON	Cardiac Resynchronization Therapy (CRT) turned ON in conjunction with optimal medical therapy

Certain Agreements:

Principal Investigators are NOT employed by the organization sponsoring the study.

There IS an agreement between Principal Investigators and the Sponsor (or its agents) that restricts the PI's rights to discuss or publish trial results after the trial is completed.

The agreement is:

	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is less than or equal to 60 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	The only disclosure restriction on the PI is that the sponsor can review results communications prior to public release and can embargo communications regarding trial results for a period that is more than 60 days but less than or equal to 180 days. The sponsor cannot require changes to the communication and cannot extend the embargo.
	Other disclosure agreement that restricts the right of the PI to discuss or publish trial results after the trial is completed. Restriction Description: In most cases, contracts allow investigators to publish study results per the publication plan/protocol following Medtronic's review to determine whether confidential information ("CI") is disclosed. Any such CI is deleted prior to publication/presentation. Medtronic may not censor/interfere with the publication except as described. Investigators may not publish any single-site publications until the main multi-site study publication has occurred.

Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
