What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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.

Summary

This study looks at whether new, fully automated software can measure heart muscle strain as accurately as the current manual method during heart surgery. The manual method takes about 5 minutes, which is often too slow in the operating room. The automated method takes just seconds. Researchers will enroll 70 adult heart surgery patients and compare the two measurement techniques.

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 automated strain analysis proves reliable, it could speed up heart function assessment during surgery, helping doctors make faster decisions.
What could go wrong
This is a small, early-stage observational study (70 participants) comparing measurement methods, not testing a treatment. Results may not apply to all patients or settings.
