Summary

This small study will test whether empagliflozin, a drug typically used for diabetes, can improve abnormal heart patterns in people with Brugada syndrome. Ten participants will take the drug daily for three months, and researchers will monitor their heart rhythms and any side effects. The goal is to see if the drug can reduce the risk of dangerous heart events.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Empagliflozin (a diabetes drug that lowers blood sugar by helping the kidneys remove it)
What this could lead to
If it works, this could point toward a new treatment option for Brugada syndrome, a rare heart condition that can cause dangerous heart rhythms.
What could go wrong
This is a very small early-phase trial with only 10 people, so results may not apply to everyone. The drug also has known side effects like infections and kidney issues.
