What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing
Running, but no longer taking on new participants.
Completed This study
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.

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.
