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 Results may not be published yet.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

Summary

This study measured how fast pulse waves travel from the heart to different arteries in 40 patients undergoing heart surgery with a heart-lung machine. The goal was to see if this speed can detect when blood pressure in central arteries differs from that in arm or leg arteries. Researchers used non-invasive arm and leg cuffs plus a standard wrist catheter to track these changes.

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 improve how doctors monitor blood pressure during heart surgery, potentially leading to better decisions about medication.
What could go wrong
This is a small, observational study with only 40 participants, so results may not apply to all patients. It does not test a treatment, so direct patient benefit is not expected.

This is an AI summary of the original study and may miss details. Read our disclaimer.
