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 Results may not be published yet.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

Summary

This study will follow 1200 people who have had a heart attack or unstable angina and also have sleep apnea. Researchers will collect blood, urine, and stool samples to understand how sleep apnea affects metabolism and heart risk. The goal is to build an AI-based tool to better predict future heart attacks or strokes in these patients.

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 a more accurate way to predict heart and brain events in people with both sleep apnea and acute coronary syndrome.
What could go wrong
This is an observational study, not a treatment trial. It will not directly test any therapy, and the model may not be accurate enough for widespread use.

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