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 Results may not be published yet.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

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This status has not been confirmed recently, so it may be out of date.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 pilot study is testing whether a smartphone app called HeartMate can help people with heart disease manage their condition from home. Over six weeks, participants use the app for daily heart checks, guided exercise, breathing training, and a mind program, with weekly coaching from staff. The goal is to see if this digital approach improves physical function, heart risk factors, and well-being compared to usual care. Because this is an early exploratory trial, the results will help design a larger, more definitive study.

What this could mean

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

Active substance
a 6-week smartphone application program called HeartMate that includes daily heart checks, exercise, breathing training, and remote coaching
What this could lead to
If it works, this could point toward a convenient, home-based way to manage heart disease risk factors and improve physical function without frequent hospital visits.
What could go wrong
This is a small pilot study, so results are preliminary and may not confirm effectiveness. The program requires a smartphone and daily engagement, which may not suit everyone.

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 200 people

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

Expected to start

Jul 2026

An estimate. Start dates often move.

Expected to finish

Aug 2028

An estimate. End dates often move.

Lead sponsor

Other sponsor
