NCT ID NCT06046339

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 Results may not be published yet.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This status has not been confirmed recently, so it may be out of date.

Summary

This study looked at 116 people who had a cardiac arrest outside the hospital and were treated with a machine called ECMO (which pumps and oxygenates blood). Researchers measured how well the heart was pumping at 28 days and 90 days after the arrest. The goal was to understand if and how heart function improves over time in these very sick patients.

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 help doctors understand how well the heart recovers after a severe cardiac arrest treated with ECMO, guiding future treatment decisions.
What could go wrong
This is an observational study that only collects existing data, not testing a new treatment. Results may not apply to all patients, and the small size limits conclusions.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.

Inclusion Criteria: * Implementation of an extracorporeal membrane oxygenation (ECMO) following an acute coronary syndrome (ACS) defined for the purposes of the study by the existence of at least one of the following criteria: ST segment elevation or depression on the electrocardiogram associated with chest pain and elevated plasma troponin levels; a coronary angiography showing at least one significant coronary lesion and/or having required revascularization. Confirmation of an ischemic etiology by post-mortem examination. A coronary lesion is considered significant if it is described by the cardiologist as: acute and responsible for a reduction in the caliber of the artery strictly greater than 70% and less than 99% for a severe stenosis, and 100% for a complete stenosis. * Patients hospitalized at Necker Hospital for pre-hospital cardiac arrest between January 1, 2015 and October 31, 2019. * Sending to living patients of the study information note, a period of one month is given to the patients to oppose the use of their data for the study. Exclusion Criteria: * Extracorporeal membrane oxygenation implementation outside the context of refractory out-of-hospital cardiac arrest * In-hospital cardiac arrests * Obvious non-cardiological cause of cardiac arrest * Cardiac arrests unrelated to acute coronary syndrome * Cardiac arrests for which no etiology has been found * Patients opposed to the use of their data
