ECMOCardiogenic ShockTemporary Mechanical Circulatory Support
Investigational drug(s) / intervention(s)
phenotype
phenotype: Eligible patients will receive orally the cocktail probe drugs ( via a naso-gastric tube at D3 after tMCS implantation or after the beginning of the cardiogenic shock for the control group) and via an oral administration at 14 days after tMCS explantation (or cardiogenic shock termination for the control group defined as: no need to use inortropic or vasopressive agent and absence of organ insufficiency). The phenotyping probe drugs of the Geneva Cocktail will be given as: one capsule containing the remaining probe 'cocktail' drugs. According to clinical experience in our intensive care unit department, inflammation related to tMCS peaks at D3 after tMCS implantation.
Blood samples will be collected from the central venous line 2 hours after drug administration for CYP phenotyping and genotyping. Inflammatory markers blood levels (Il-6, TNF-α, Il-1β, IFN-γ) will be measured at tMCS implantation or shock initiation and at the same time than CYP phenotyping.
Study summary
Prospective open label observational study including patients requiring a tMCS (VA-ECMO or Impella® CP) or in in cardiogenic shock according to the SCAI (Society for Cardiovascular Angiography and Interventions) ESC (European Society of Cardiology) definition 41,42 and not requiring or not eligible to tMCS (ECMO, Impella®, intra-aortic balloon pump) (control group).

Inclusion Criteria:
* Male and female patients presenting a refractory cardiogenic shock, requiring temporary mechanical circulatory support (tMCS), with either the use of veno-arterial extracorporeal membrane oxygenation (VA-ECMO) or a micro-axial pump device (Impella® CP).
* Male and female patients in cardiogenic shock according to the SCAI (Society for Cardiovascular Angiography and Interventions) ESC (European Society of Cardiology) definition and not requiring or not eligible to temporary mechanical circulatory support (tMCS). (e.g. ECMO, Impella®, intra-aortic balloon pump) (control group)
* Age \> 18 years old
* Comprehension of French
* Ability to give consent (consent will be sought from the therapeutic representative or from relatives as the patient will be sedated and intubated. Definitive consent will be sought at patient's second blood sample planned after tMCS explantation (in case of patient's favorable outcome).
Exclusion Criteria:
* Male and female patients presenting a refractory ARDS requiring veno-venous extracorporeal membrane oxygenation (VV-ECMO)
* Inability to receive the Geneva cocktail by enteral way
* Severe or terminal Renal impairment (defined as GFR\<30ml/min according to Cockroft-Gault)
* Severe chronic hepatic insufficiency (CHILD B-C)
* Sensitivity to any of the drugs used in the Geneva Cocktail
* Intake of drugs altering CYPs activity (Strong inhibitor or inducer based on https://www.hug.ch/sites/hde/files/structures/pharmacologie\_et\_toxicologie\_cliniques/a5\_cytochromes\_6\_2.pdf)
Primary outcome measure(s)
Evaluate the impact of temporary mechanical circulatory support on the activity of CYPs as measured with metabolic ratios MRs (CYP activity at D3 post tMCS implantation and 14 days after tMCS explantation vs the activity of CYPs in the control grou — During the ECMO CYP450 3A4, 2C19, 2D6, 2B6, 1A2 activity will be assessed in using the metabolic ratio of the following probe respectively: midazolam, esomeprazole, dextrometorphan, bupropion and caffein.
