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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This study tests whether the drug landiolol can safely keep heart rate below 90 beats per minute during major surgery in 114 patients with heart risks. The goal is to see if this approach is feasible and might reduce heart injury after surgery. Participants receive the drug through an IV during and after their operation.

What this could mean

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

Active substance
Landiolol (a short-acting beta-blocker given intravenously)
What this could lead to
If successful, this could show that controlling heart rate during surgery reduces heart damage in at-risk patients, paving the way for a larger trial.
What could go wrong
This is a small feasibility trial, not designed to prove effectiveness. The drug may cause low blood pressure or require additional medications. Results may not apply to all surgery types.
