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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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 looking at overweight patients with chronic heart failure (CHF), to compare the effects of a modified fat diet with a reduced glycaemic load (diet 1); and a conventional low fat, high carbohydrate diet (diet 2) on:

* insulin sensitivity (using the homeostasis model assessment \[HOMA\] model)
* lipid profile
* symptomatic status (6 minute walk distance and Heart Failure Quality of Life \[HF QOL\] Questionnaire)
* body weight
* inflammatory mediators (tumor necrosis factor \[TNF\] alpha, C-reactive protein \[CRP\], interleukin-6 \[IL-6\])

The hypotheses of this study are:

* Diet 1 will be associated with lower insulin resistance than diet 2.
* The lipid profile will be better in CHF patients on diet 1 than on diet 2.
* Patients on diet 1 will have a better symptomatic status than patients on diet 2.
* Diet 1 will maintain body weight in patients with CHF as well as diet 2.
* Diet 1 will suppress the expression of TNF-alpha, CRP and IL-6 more than diet 2.
