NCT ID NCT07285915
First seen Jun 24, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether long-term stress, measured by cortisol levels in hair, is linked to cardiac arrest. Researchers will take a small hair sample from 136 patients who had a cardiac arrest or heart attack. The goal is to see if higher stress levels over the past three months are associated with worse outcomes. This is an observational study, so it does not test any treatment.

If successful, this could help doctors understand how chronic stress contributes to cardiac arrest and improve prevention strategies.
What could go wrong
