Prognostic Implication of Pre-Cannulation Cardiac Arrest in Patients Undergoing Extracorporeal Membrane Oxygenation for the Management of Cardiogenic Shock.

In our cohort, pre-ECMO cardiac arrest carries a negative prognostic value across all indications and is associated with an increased prevalence of neurological-etiology death. This finding is true in patients with sustained ROSC as well as those resuscitated with eCPR. Cardiac arrest can inform survival probability with VA-ECMO as early implementation of VA-ECMO may mitigate adverse outcomes in patients at the highest risk of hemodynamic collapse.
