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 Results may not be published yet.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.

Summary

This study looks at heart pumps (Impella) after they have been used in patients with heart failure. Researchers will analyze deposits and biological material on the pumps and see if they relate to patient health or medical history. The goal is to learn more about how the pump interacts with the body, which could help improve future care. About 200 patients who had the pump for several days or more will be included.

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
This study could help doctors understand how the Impella pump interacts with the body, potentially leading to safer use and better outcomes for heart failure patients.
What could go wrong
This is an observational study, not a treatment trial. It will not directly test a new therapy, and findings may not lead to immediate changes in patient care.
