If the ExtraCorporeal Membrane Oxygenation (ECMO) improves survival in the management of refractory cardiac arrest (RCA), this technique is still an invasive technique, not devoid of complications and requiring intensive care that can have serious consequences for patients. If the studies so far show an acceptable quality of life post ECMO in refractory cardiac arrest, the study looks about the quality of life of our patients in Grenoble who survived a refractory cardiac arrest between 2006 and 2018 at the hospital university Grenoble Alps and the factors influencing this quality of life.

Inclusion Criteria:

• Adult >18 years
• Admission to intensive care unit after a Refractory Cardiac Arrest
• Hemodynamic instability after resumption of spontaneous cardiac activity.
• Non-opposition of the patient or his relatives
• Admission to intensive care unit From 2006 Through 2018

Exclusion Criteria:

• ECMO for hypothermia or drug intoxication.
• Comorbidity contraindicated the ECMO
• Patients dead before hospital discharge

monocentric study based on clinical data and quality of life assessement,

Retrospective step :

• Clinical data collection for live patients admissed for Refractory Cardiac Arrest with ECMO from january 2006 through december 2018,
• Clinical data collection for live patients admissed for Refractory Cardiac Arrest without ECMO from january 2015 through december 2018,

Prospective step:

• Quality of life assessment via telephone interview based on SF36 questionnaire performed for live patients admissed for Refractory Cardiac Arrest with ECMO from january 2006 through december 2018
• Quality of life assessment via telephone interview based on SF36 questionnaire performed for live patients admissed for Refractory Cardiac Arrest without ECMO from january 2015 through december 2018
