The Role of Stress in Cardiac Arrest (Cortizol CPR)

The aim of this study is to assess long-term stress in patients after an out-of-hospital cardiac arrest. To do this, we will measure levels of the stress hormone cortisol in hair samples. Cortisol is produced in larger amounts during periods of ongoing stress and builds up in the hair as it grows. Because hair grows about 1 cm per month, a 3 cm hair sample can show your average stress level over the past three months. The results will be compared with anonymized information from your medical records and the care you received before and during your hospital stay.
