Heart recovery after cardiac arrest: ECMO patients studied
NCT ID NCT06046339
First seen Jun 26, 2026 · Last updated Jun 26, 2026
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.

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
