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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 looks at two ways to perform coronary artery bypass grafting, a surgery that reroutes blood around blocked heart arteries. One method uses a single chest artery for the graft, while the other uses both chest arteries. Researchers will compare long-term survival, stroke risk, and wound complications in 666 adults who had first-time bypass surgery. The goal is to see whether using both arteries offers better outcomes than the standard single-artery approach.

What this could mean

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

Active substance
Bilateral internal thoracic artery (BITA) grafting compared with single internal thoracic artery (SITA) grafting during coronary artery bypass surgery
What this could lead to
If BITA grafting proves safer and more durable, it could become the preferred standard for bypass surgery, improving long-term survival and reducing repeat procedures.
What could go wrong
This is a retrospective review, not a randomized trial, so hidden differences between groups could skew results. BITA grafting may also raise the risk of sternal wound infections, especially in certain patients.
