Study Description

Brief Summary:

This is a steering group approved substudy to the Target Temperature Management trial (TTM, ClinicalTrials.gov Identifier: NCT01020916). TTM compares the effect of two strictly controlled temperature regimes for survivors of out-of-hospital cardiac arrest.

The primary aim of this sub-study is to compare the amount of cognitive impairment in cardiac arrest survivors treated with 33 degrees and 36 degrees and with a matched group of control patients with myocardial infarction.

Our secondary aims are:

To investigate the impact of cognitive impairment on our patients' ability to participate in society and their health related quality of life.
To investigate the relationship between our patients cognitive impairments and their relatives/informants health related quality of life and feelings of burden.
To test the hypothesis that the simple cognitive screening battery used in the TTM main trial is sensitive enough to detect all patients with significant cognitive disability.
