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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 trial tests whether planning coronary artery bypass grafting (CABG) using a non-invasive CT scan (CCTA) works as well as the standard invasive angiography (CAG). About 826 people with blocked heart arteries will be randomly assigned to have their surgery planned with one of the two imaging methods. The main goal is to compare major heart-related events within one year, such as heart attacks, strokes, and repeat procedures. If CCTA proves non-inferior, it could offer a safer, more comfortable alternative for surgical planning.

What this could mean

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

Active substance
Coronary computed tomography angiography (CCTA) as a surgical planning tool
What this could lead to
If successful, this could make bypass surgery planning less invasive and more accessible, potentially reducing risks and improving recovery.
What could go wrong
The trial is still in progress, and results may not show non-inferiority. CCTA may miss details that invasive angiography captures, and the approach may not suit all patients.

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

Study facts

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 826 people

The number the study aims to enrol. It can still change while the study runs.
