Using VA-ECMO to treat cardiogenic shock in heart attack patients

Official title: Assessment of ECMO in Acute Myocardial Infarction With Non-reversible Cardiogenic Shock to Halt Organ Failure and Reduce Mortality (ANCHOR)

Run by Assistance Publique - Hôpitaux de Paris · NCT04184635 · Data updated 2026-11-12

This study is testing if using a special heart support machine along with another device can help heart attack patients in severe shock feel better compared to just standard treatment.

Is this trial a fit for you?

Likely a good fit

Ideal candidates are adults experiencing cardiogenic shock due to acute myocardial infarction who require immediate revascularization.

Probably not a fit

Patients with shock from causes other than acute myocardial infarction or those who are moribund at the time of randomization may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This study evaluates the effectiveness of venoarterial extracorporeal membrane oxygenation (VA-ECMO) combined with intra-aortic balloon pump (IABP) support in patients experiencing cardiogenic shock due to acute myocardial infarction (AMI). It aims to determine if this combination improves patient outcomes compared to optimal medical treatment alone. Patients will be closely monitored, and those who do not respond to conventional treatment will have access to VA-ECMO as a rescue option. The study is designed to provide critical data on the potential benefits of early intervention in this high-risk population.

Why it matters

Potential benefit: If successful, this approach could significantly reduce mortality rates in patients suffering from cardiogenic shock due to heart attacks.

How similar studies have gone: While the use of VA-ECMO in this context is gaining traction, high-level evidence is still lacking, making this approach somewhat novel.
