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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

This study looks at whether a special type of ECG (called wavECG) can predict atrial fibrillation, a common irregular heartbeat after open-heart surgery. Researchers will follow 100 patients having their first heart surgery, using wavECG and echocardiograms to see who develops atrial fibrillation. The goal is to improve prediction so doctors can better manage risk.

What this could mean

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

What this could lead to
If successful, this could lead to better prediction tools for atrial fibrillation after heart surgery, helping doctors identify high-risk patients earlier.
What could go wrong
This is an early exploratory study with only 100 participants. The new ECG technology may not prove accurate enough for clinical use, and results may not apply to all heart surgery patients.
