Biomarkers After Out-of-hospital Cardiac Arrest- a STEPCARE Substudy

Summary

A prospective multicenter biomarker study with adult patients treated on intensive care units after out-of-hospital cardiac arrest. Patients will be recruited from specific sites participating in the Sedation, Temperature and Pressure After Cardiac Arrest and Resuscitation (STEPCARE) trial. (ClinicalTrials.gov ID NCT05564754). Blood samples will be collected at 12, 24, 48, and 72 hours after randomization in selected sites, aliquoted and frozen on-site. After trial completion, samples will be stored in a central biobank. Sample analysis will be performed in batch after trial completion. Functional outcome will be assessed at 30 days and 6 months after cardiac arrest.
