Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Summary
Brief summary
This study is a feasibility study of the HeartPOD™ Heart Failure Management System with DynamicRx® (HeartPOD system) in patients with severe chronic congestive heart failure. The device being studied in this trial monitors heart function and alerts the patient and physician of necessary changes to medication. The study will assess the safety, reliability, and preliminary efficacy of the HeartPOD™ system.
