NCT ID NCT07410481
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests a new therapy called AMBET (Acceptance- and Mindfulness-Based Exposure Therapy) for treating PTSD in people who survived a cardiac arrest. About 90 adults will be randomly assigned to either AMBET or a standard talk therapy (PCT) for 12 weeks. Researchers will track PTSD symptoms, mood, sleep, and activity to see which therapy works better.
