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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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 pilot study will evaluate the efficacy and safety of CCM therapy in heart failure patients with baseline EF=50% (HFpEF) who have New York Heart Association (NYHA) Class II or III symptoms despite appropriate medication.

The terminology of the HF classification HFpEF is based on the 2016 European Society of Cardiology (ESC) Heart Failure Guidelines.
