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 This study
Running, but no longer taking on new participants.
Completed
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 Results may not be published yet.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
Cancelled before anyone took part.

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.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.
Status unknown
This status has not been confirmed recently, so it may be out of date.

Summary

Researchers test whether cutting certain nerves around the heart during open-heart surgery can prevent atrial fibrillation, a common irregular heartbeat after the operation. The trial enrolls 560 adults scheduled for elective open-heart surgery. Half receive standard surgery plus nerve cutting, and half receive standard surgery alone. The team tracks heart rhythm for up to a week after surgery to see if the nerve cutting reduces episodes of atrial fibrillation.

What this could mean

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

Active substance
surgical cutting of heart nerves (cardiac sympathetic denervation)
What this could lead to
If it works, this could offer a way to prevent irregular heartbeats after heart surgery, reducing the need for extra medications or procedures.
What could go wrong
Cutting nerves around the heart may not stop atrial fibrillation, and it could cause unwanted effects like changes in heart rate or blood pressure. The trial is still testing whether the benefits outweigh the risks.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: Age ≥18 years scheduled for elective open-heart surgery via median sternotomy (CABG, valve repair/replacement, or combined procedures). \- Exclusion Criteria: * Preoperative permanent pacemaker or ICD. * Emergency surgery, active endocarditis, or severe hemodynamic instability. * Concomitant planned surgical ablation (e.g., Cox-Maze procedure) or left atrial appendage occlusion. * Preoperative use of antiarrhythmic drugs (AADs) other than beta-blockers within 5 half-lives of surgery.
