Could a simple Beta-Blocker stop a second cardiac arrest?
NCT ID NCT07405229
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study looks at whether low-dose beta-blockers can reduce dangerous heart rhythms in people who have survived a cardiac arrest with no clear cause. About 218 participants will receive one of several beta-blockers and be followed for up to 3 years. The goal is to see if this treatment lowers the need for shocks from an implanted defibrillator.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
beta-blocker (propranolol, nadolol, atenolol, bisoprolol, or metoprolol)
What this could lead to
If beta-blockers work, this could give doctors a standard way to lower the chance of repeat cardiac arrest in people with unexplained ventricular fibrillation.
What could go wrong
This is a relatively small, early-phase study. Beta-blockers may not reduce arrhythmias in these patients, and side effects like fatigue or low blood pressure could occur.
