Can a heart drug tame stress inflammation?
NCT ID NCT06263452
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests whether a single dose of the beta-blocker propranolol can reduce inflammation caused by psychological stress. Researchers will measure immune markers and brain activity in 120 healthy young adults before and after a stressful task. The goal is to understand the link between stress and heart disease risk.

- What this could lead to
- If successful, this study could reveal how stress triggers inflammation and point toward new treatments to lower heart disease risk.
- What could go wrong
- This is an early-phase, small study (120 people) focused on understanding mechanisms, not testing a treatment. Results may not lead to direct therapies.
