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 Results may not be published yet.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

Details not published

Summary

This trial tests whether using detailed CT images of the heart's arteries to plan invasive procedures can reduce radiation exposure, procedure time, contrast use, and tools needed. Adults with stable angina and significant blockages are randomly assigned to receive either standard care or a CT-guided approach. The goal is to see if this smarter planning makes the procedure more efficient and potentially safer.

What this could mean

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

Active substance
CCTA-guided focused coronary angiography examination
What this could lead to
If effective, this approach could make heart procedures faster, safer, and less resource-intensive.
What could go wrong
The trial is relatively small and early, so benefits may not be confirmed or widely applicable.
