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The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.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 sub-study to the large pragmatic Target Temperature Management 2 Trial (TTM2-trial, ClinicalTrials.gov Identifier: NCT02908308), assessing effectiveness of controlled hypothermia after out-of-hospital cardiac arrest (OHCA).

This study is designed to provide detailed information on cognition after OHCA and its relationship to associated factors as emotional function, fatigue, and sleep. A secondary aim is to utilize this information to validate a neurocognitive screening battery used 6 months after OHCA in the TTM2-trial.

Approximately 7 and 24 months after OHCA, survivors at selected TTM2 study sites will perform a standardized neuropsychological assessment including performance-based tests of cognition and questionnaires of behavioral and emotional function, fatigue, and insomnia. At 1:1 ratio, a control group of myocardial infarction (MI) patients but no occurrence of cardiac arrest will be recruited and perform the same test battery. Group differences at 7 and 24 months will be analyzed per cognitive domain (verbal, visual/constructive, short-term working memory, episodic memory, processing speed, executive functions). Results of the OHCA survivors on the TTM2 neurocognitive screening battery will be compared with neuropsychological test results at 7 months time.
