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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 develops and tests an AI system that reads de-identified patient admission notes to classify four types of coronary syndromes, including heart attacks and angina. The tool is designed to protect patient privacy while helping doctors diagnose more accurately and quickly. Researchers will evaluate the system using 10 hospital records and additional external datasets.

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 includes (1) de-identified clinical encounter records and (2) physician participants for usability testing. For record-based cohorts, eligible encounters contain an admission/presentation History of Present Illness (HPI) (text or image-derived text) sufficient for 4-class coronary syndrome subtyping (e.g., STEMI, NSTEMI, unstable angina, chronic coronary syndrome). Records are analyzed at the encounter level and are organized into five dataset-based cohorts (internal validation, multicenter external validation, ED external validation, English EHR external validation, and clinician usability). Reference labels are assigned using a prespecified clinical adjudication process.

Ages

Inclusion Criteria:Hospital encounters with admission HPI documenting sym 2a4afaef-9dc1-47fc-874f-9dffaf7… evant to coronary syndrome subtyping. Cases with sufficient documentation to assign one of four target subtypes (STEMI, NSTEMI, UA, CCS) by adjudication. \- Exclusion Criteria: Unclear subtype or incomplete/uncertain time information preventing gold standard assignment. Non-CHD primary reason for admission after screening (for MIMIC-IV cohort). \-
