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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 study tests whether artificial intelligence can evaluate how well surgeons perform a key step in heart bypass surgery. Researchers will compare AI scores to those from human experts. The trial involves 284 patients undergoing bypass grafting and aims to see if AI can reliably assess surgical skill.

What this could mean

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

What this could lead to
If successful, this could lead to AI tools that help train surgeons and improve surgical quality in heart bypass procedures.
What could go wrong
This is an observational study, not a treatment trial. The AI may not match expert judgment, and results may not apply to other surgeries or hospitals.

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

Who can take part

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

Who is studied

The study population consists of adult patients who meet the inclusion criteria of being aged 18 years or older, undergoing their first isolated coronary artery bypass grafting (CABG) surgery using internal mammary artery-to-left anterior descending artery bypass grafting. All participants should signed written informed consent prior to inclusion in the study. Exclusion criteria include patients with acute coronary syndrome, contraindications to coronary CT angiography or coronary angiography, and those with renal insufficiency or active liver disease. Specifically, patients with persistently elevated serum transaminases of unknown cause or those with any serum transaminase levels exceeding three times the upper limit of normal will also be excluded from the study.
