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
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 This study
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 investigates whether different types of sleep apnea—a condition where breathing repeatedly stops during sleep—are linked to future heart problems or death in people who have recently had a heart attack. Researchers will use a home sleep test called polygraphy to measure breathing, oxygen levels, and heart rate in about 2,000 participants. By analyzing this data, they hope to identify distinct patient groups with varying risk levels, which could eventually lead to personalized treatments to improve heart health.

What this could mean

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

Active substance
Sleep polygraphy (a diagnostic test that records breathing, oxygen levels, and heart rate during sleep)
What this could lead to
If successful, this could identify heart attack survivors with specific sleep apnea patterns who face higher risks, paving the way for targeted treatments to improve their outcomes.
What could go wrong
This is an observational study, so it cannot prove cause and effect. The findings may not lead to immediate changes in care, and the complex data analysis might not yield clear, actionable clusters.
