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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 system can analyze standard heart tracings (ECGs) to detect pulmonary hypertension—a serious but often unnoticed condition—before surgery. About 1,380 adults scheduled for non-cardiac surgery will be randomly assigned to get the AI screening or usual care. The goal is to see if the AI finds more cases and helps reduce surgical complications.

What this could mean

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

Active substance
Artificial intelligence-enabled electrocardiography system
What this could lead to
If it works, this could become a routine, low-cost way to catch dangerous heart conditions before surgery, potentially preventing complications.
What could go wrong
This is an early-stage trial with no phase assigned, so the AI may not be accurate enough in real-world use. It also only looks at detection, not treatment.

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 1,380 people

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

Expected to start

Jan 2026

An estimate. Start dates often move.

Expected to finish

Jan 2027

An estimate. End dates often move.

Lead sponsor

A government agency

The lead sponsor is a government body.

Who can take part

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

Healthy volunteers

Not accepted

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

Show the full entry requirements

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

Inclusion Criteria: 1. Age between 18 and 80 years. 2. Patients scheduled for non-cardiac surgery under general anesthesia. 3. Patients who have a scheduled standard preoperative electrocardiogram (ECG). 4. Patients capable of understanding the study and willing to provide medical records for research purposes, and who have signed the informed consent form. Exclusion Criteria: 1. Patients scheduled for emergency surgery. 2. Patients who explicitly refuse to participate or withdraw consent. 3. Patients with specific comorbidities that interfere with ECG interpretation or data collection (e.g., implanted pacemakers).
