Simple nerve block could prevent Post-Surgery heart rhythm problems
NCT ID NCT05932485
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a stellate ganglion block (a nerve injection) before coronary artery bypass surgery can prevent new atrial fibrillation, a common complication. 108 patients were included. The approach aims to calm the nervous system and reduce inflammation. Results could lead to a simple way to lower stroke and heart failure risks after surgery.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
stellate ganglion block with ropivacaine
What this could lead to
If it works, this could offer a simple procedure to lower the risk of atrial fibrillation after heart bypass surgery, reducing stroke and other complications.
What could go wrong
This is a small, single-center study with 108 patients. The nerve block may not work for everyone, and there are risks like bleeding or nerve damage from the injection.
