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 Results may not be published yet.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)

Summary

This study of 102 heart surgery patients examined whether drops in brain oxygen levels during surgery are linked to memory or thinking problems after the operation. Researchers used a special monitor to track brain oxygen and tested patients' thinking skills before and after surgery. The goal was to identify risk factors that could help prevent cognitive decline in future 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 it works, this could help identify patients at higher risk for cognitive decline after heart surgery, leading to better monitoring or preventive strategies.
What could go wrong
This is a small, completed observational study, not a treatment trial. The findings may not apply to all heart surgery patients or lead to direct changes in care.
