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 Results may not be published yet.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

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.

Summary

This study tests whether ultrasound scans can detect leftover fluid in the lungs and veins of people hospitalized for heart failure. About 580 adults will get scans at several points during their stay, but doctors won't see the results. Researchers will then track who is readmitted or dies within 90 days to see if the scans predict problems better than standard exams.

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 help doctors identify which heart failure patients need more treatment before leaving the hospital, potentially reducing readmissions.
What could go wrong
This is an observational study, not a treatment trial, so it won't directly improve outcomes. The ultrasound method may not prove better than standard checks.
