What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
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
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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 treat a fast, dangerous heart rhythm called ventricular tachycardia in people with coronary artery disease and relatively good heart function. One treatment uses a catheter to burn the tiny area causing the problem (radiofrequency ablation), and the other uses a small device implanted in the chest to shock the heart back to normal (defibrillator). The goal is to see which approach leads to fewer serious events like death or hospital visits over three years. About 268 adults with a history of heart attack and a preserved pumping ability will take part.

Phase

Not a phased trial

Phase numbers describe drug development. The registry uses this when they do not apply, as it does for trials of devices, procedures or behaviour changes, and for observational studies.

Participants

About 268 people

The number the study aims to enrol. It can still change while the study runs.

Other sponsor

The registry's catch-all category, for sponsors it does not file as a company, a government agency, or a research network.
