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 Results may not be published yet.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.

Summary

This Canadian study tests whether remote monitoring of implantable defibrillators can replace regular in-clinic checkups. Over 1,100 participants will either use a home transmission system or receive usual care. The goal is to see if remote monitoring can detect heart issues faster and reduce hospital visits without increasing risks.

What this could mean

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

Active substance
Remote patient management via home monitoring device
What this could lead to
If successful, this could allow heart device patients to be monitored from home, reducing the need for frequent clinic visits and catching problems earlier.
What could go wrong
This is a large trial but still observational in nature; it may not show clear benefits over standard care, and remote monitoring could miss some urgent issues.
