Evaluation of the 1-year Prognosis of Patients Under Veno-arterial Extracorporeal Membrane Oxygenation for Cardiogenic Shock With Blood Transfusion Requirement

The primary objective of this work is to study the 1-year prognosis of patients who received Veno-arterial extracorporeal membrane oxygenation for cardiogenic shock with the need for blood transfusion. Secondary objectives are to determine whether the transfusion strategy used (liberal or restrictive) still has an impact on overall mortality. We will also determine the factors associated with overall in-hospital mortality and look at the impact of transfusion in relation to the risk of hemolysis on the consequences in the occurrence of long-term chronic renal failure.
