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 Results may not be published yet.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 looks at people whose coronary arteries are abnormally widened (coronary artery ectasia). Researchers want to see if exercise stress tests and certain blood markers can detect when the heart muscle isn't getting enough blood. The goal is to better understand the link between inflammation and blood-flow problems in this condition.

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 patterns emerge, this could point toward better ways to detect heart-muscle blood-flow problems in people with coronary artery ectasia.
What could go wrong
This is an observational study with only 90 participants, so any links found will need much larger trials to confirm. It does not test a treatment.

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