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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a machine learning model can predict the outcome of a common heart procedure — placing a stent to open a hardened, calcified artery. Researchers will measure blood flow and pressure before and after the procedure in 100 adults with coronary artery disease. The goal is to see if the AI can accurately forecast whether the stent successfully restores blood flow.

What this could mean

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

Active substance
machine learning model integrating coronary flow and pressure measurements
What this could lead to
If successful, this AI tool could help doctors predict which patients will benefit most from coronary stenting, potentially improving outcomes and reducing repeat procedures.
What could go wrong
This is a small, early-stage study focused on data analysis, not a treatment. The AI model may not generalize to broader populations or different hospital settings.
