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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 an artificial intelligence (AI) tool can help emergency room doctors interpret heart CT scans more accurately. About 530 adults with chest pain and intermediate risk of a heart attack will be randomly assigned to have their scans read with or without AI assistance. The goal is to see if the AI tool improves the doctors' ability to correctly rule out serious coronary artery disease.

What this could mean

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

Active substance
AI-based coronary CT interpretation software (Angiomics)
What this could lead to
If successful, this AI tool could help emergency doctors diagnose heart attacks more accurately and quickly, especially when radiologists are not available.
What could go wrong
This is a relatively early-stage trial testing a tool in a controlled setting. The AI may not improve accuracy in real-world practice, and results may not apply to all hospitals or patient groups.

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

Study facts

What this study's own registry entry says, in plain language.

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 530 people

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

Expected to start

Nov 2025

An estimate. Start dates often move.

Expected to finish

Aug 2027

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.

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Adults aged 18 years or older * Patients presenting to the emergency department with chest pain * Patients assessed as intermediate risk (Heart Score 4-6) Exclusion Criteria: * Prior history of coronary revascularization (coronary artery bypass graft surgery or stent placement) * Presence of intracardiac metallic devices such as pacemaker or prosthetic heart valves * Contraindications to contrast media (e.g., contrast allergy, severe renal impairment with eGFR \< 30 mL/min/1.73 m²) * Patients unable to cooperate (e.g., severe anxiety, non-cooperation)
