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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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
High levels of good cholesterol (HDL) in our blood decreases our chance of having a heart attack. This relates in part to the role good cholesterol plays in reducing build up of fat in the arteries. However, good cholesterol has many other protective effects. We have recently identified three enzymes (proteins) activated by HDL in cells lining the blood vessels, which may be responsible for some of HDL's protective actions.
