NCT02754193

Brief Summary

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).

Outcome Measures

Primary Outcomes (1)

  • All-cause Mortality

    The study objective is to determine whether early moderate hypothermia (33°C≤ T°C ≤34°C) is superior to normothermia (37°C ± 0.3°C) in patients with cardiogenic shock treated with VA-ECMO with respect to 30-day mortality

    Day 30

Secondary Outcomes (17)

  • All-cause mortality

    Hour 48, Day 7, Day 60, day 180

  • Venous Arterial ECMO duration

    up to 180 days (from date of randomization until ECMO weaning)

  • Death

    day 30, Day 60, Day 180

  • cardiac transplant

    day 30, Day 60, Day 180

  • escalation to Left Ventricular Assist Device

    day 30, Day 60, Day180

  • +12 more secondary outcomes

Study Arms (2)

Moderate hypothermia

EXPERIMENTAL

Moderate hypothermia :Patients with cardiogenic shock treated with arteriovenous ECMO to a strategy of moderate hypothermia during 24 hours (Temperature at 33°C≤ T°C ≤34°C) associated with usual care

Other: moderate hypothermia

Normothermia

NO INTERVENTION

Normothermia: Patients with cardiogenic shock treated with arteriovenous ECMO to a strategy of normothermia (36°C≤ T°C ≤37°C) associated with usual care

Interventions

moderate hypothermia will be induced using the heat controller of the VA-ECMO circuit. Temperature will be maintained between 33°C≤ T°C ≤34°C during 24 hours ± 1h followed by a progressive reheating (0.2±0.1°C/h) to reach 37 °C. Temperature at 37°C ± 0.3°C will be maintained during 48 hours ± 4h after having reached 37 °C.
