Heart attack survivors get a secret weapon: a mini monitor that spots hidden danger

NCT ID NCT05073419

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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

After a heart attack, patients face a high risk of dangerous heart rhythms, but current monitoring methods may miss them. This trial tests whether a small implantable cardiac monitor (ICM) placed under the skin can catch these rhythms earlier and help doctors adjust treatment. Two hundred adults who recently had a heart attack will either receive the ICM or standard follow-up care. The goal is to see if the device leads to more timely and effective treatment changes.

What this could mean

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

Active substance
Implantable cardiac monitor (ICM)
What this could lead to
If successful, this could show that routine monitoring with an ICM helps doctors detect and treat heart rhythm problems earlier after a heart attack, potentially improving survival.
What could go wrong
This is a small, early-phase study (200 participants) focused on detecting arrhythmias, not on proving survival benefit. The monitor may find harmless rhythms that lead to unnecessary procedures, or it may not change outcomes at all.

Study facts

What this study's own registry entry says, in plain language.

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.

Started

Aug 2022

Expected to finish

Dec 2026

An estimate. End dates often move.

Lead sponsor

Other sponsor

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

Who can take part

This study's own entry requirements. Only the study team can say for certain whether you qualify.

Ages

18 years and older

Sex

Anyone

Healthy volunteers

Not accepted

This study is not open to healthy volunteers. The entry requirements below say who it is open to.
