Effects of Induced Moderate HYPOthermia on Mortality in Cardiogenic Shock Patients Rescued by Veno-arterial ExtraCorporeal Membrane Oxygenation (ECMO)

Effects of Induced Moderate HYPOthermia on Mortality in Cardiogenic Shock Patients Rescued by Veno-arterial ExtraCorporeal Membrane Oxygenation (ECMO)

A multicenter, prospective, controlled, randomized (moderate hypothermia 33°C≤ T°C ≤34°C) during 24 hours ± 1h versus normothermia (36°C≤ T°C ≤37°C), comparative open trial will be conducted on two parallel groups of patients with cardiogenic shock treated with VA-ECMO.

The HYPO-ECMO trial will test the hypothesis that moderate hypothermia (temperature between 33°C≤ T°C ≤34°C) associated with VA-ECMO support results in a reduction in 30-day mortality in comparison with the normothermia group (36°C≤ T°C ≤37°C).
