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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 a coronary CT angiography (CCTA) scan can safely identify heart attack patients who do not need invasive angiography. About 300 patients with non-ST-elevation myocardial infarction (NSTEMI) will undergo CCTA before the standard invasive test. The goal is to see if CCTA can accurately spot those who can skip the invasive procedure, reducing discomfort, risk, and costs.

What this could mean

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

Active substance
Coronary CT angiography (CCTA) as an initial imaging test before invasive coronary angiography
What this could lead to
If CCTA works, many NSTEMI patients could avoid invasive angiography, reducing risks and healthcare costs.
What could go wrong
CCTA may not accurately identify all who need revascularization, and the trial is early, so results may not apply broadly.

An estimate. End dates often move.

Lead sponsor

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
