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 This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early

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.

Summary

After coronary artery bypass grafting, doctors place tubes to drain fluid from around the heart. This trial compares two ways of monitoring that drainage: using gentle negative pressure (suction) or letting it drain on its own. Researchers will track fluid buildup around the heart, total drainage volume, and complications like irregular heartbeats or bleeding in 400 adults having planned bypass surgery.

What this could mean

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

Active substance
negative-pressure drainage monitoring
What this could lead to
If negative pressure works better, it could become a standard way to drain fluid after heart bypass surgery and reduce complications like fluid around the heart.
What could go wrong
This is a single-center study of 400 people, so results may not apply everywhere. Negative pressure could also cause more bleeding or other problems, which the trial is designed to detect.
