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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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
Objective target of the registry is to investigate the prevalence of SDB as well as the clinical characteristics of patients with and without SDB as well as the predominant type of sdb.

For this purpose data from patients suffering from chronic, symptomatic heart failure with impaired left ventricular ejection fraction will be collected prospectively.
