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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.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 is looking at 400 people with weak hearts who are getting an implantable defibrillator (ICD) to prevent sudden cardiac death. Researchers want to see if detailed heart MRI scans can find structural problems that better predict who will actually have a dangerous heart rhythm. The goal is to improve how doctors decide who needs an ICD, avoiding unnecessary implants and their risks.

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 successful, this could lead to better ways to identify who truly needs an implantable defibrillator, saving lives and avoiding unnecessary procedures.
What could go wrong
This is an observational study, not a treatment trial. It may not find a clear link, and results may not change practice for years.

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

Who can take part

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

Who is studied

Patients with LV ejection fraction (LVEF) ≤35% of ischemic or nonischemic etiology (as measured by a clinical echocardiogram, ventriculogram, or radionuclide study) referred clinically for ICD insertion for primary prevention purposes (i.e. no prior history of sustained ventricular arrhythmias)

Ages

21 to 80 years

Sex

Anyone

Healthy volunteers

Not accepted

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

Inclusion Criteria: * LVEF≤35%, referred clinically for ICD insertion for primary prevention purposes (i.e. no prior history of sustained ventricular arrhythmias) * Between the ages of 21 and 80 years old * Permission of the patient's clinical attending physician Exclusion Criteria: * Patients who refuse or are unable to give consent. * Individuals with contraindications to MRI (i.e. implanted metallic objects such as pre-existing cardiac pacemakers, cerebral clips or indwelling metallic projectiles) * Minors. * Pregnant women. * NYHA Class IV heart failure. * Chronic renal insufficiency with creatinine clearance\<60 ml/min; acute renal insufficiency of any severity * Claustrophobia * Prior adverse reaction to gadolinium-based contrast
