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 Results may not be published yet.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
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This status has not been confirmed recently, so it may be out of date.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 tested a new automatic tool on a pocket ultrasound device to measure how well the heart pumps blood (left ventricle ejection fraction). Researchers compared its results to those from heart MRI, the gold standard, in 60 adults with shortness of breath, low blood pressure, or chest pain. The goal was to see if the automatic tool gives more consistent readings between different doctors than the usual visual assessment.

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 make it easier and faster for emergency doctors to accurately assess heart function using a small, portable device.
What could go wrong
This is a small, completed study focused on comparing measurement methods, not on treating a disease. The automatic tool may not be as accurate as MRI in all patients.
