Transient Circulatory Support in Cardiogenic Shock

• Conditions: Acute Cardiogenic Shock

• Registration Number: NCT03528291
• Lead Sponsor: University Hospital, Montpellier

Brief Summary

The purpose of this multicenter prospective study is to determine if the decision of transient circulatory support (TCS) in cardiogenic shock is relevant. TCS is a recommended treatment of refractory cardiogenic shock but precise indications are not definitively founded. Some studies described patients with TCS in order to establish mortality predictive scores (ENCOURAGE, SAVE), but no study has assessed the clinical relevance of the TCS decision yet. Therefore, The investigators propose to compare the characteristics and the follow-up of patients in acute cardiogenic shock, once TCS implantation was decided or not by the heart team.

Detailed Description

This French multicenter prospective observational study is aimed at determining if the decision of transient circulatory support (TCS) in cardiogenic shock is pertinent, i.e. at least as effective as the medical treatment.

All patients with cardiogenic shock for whom indication of TCS was discussed within the multidisciplinary heart team (cardiologist, intensivist and cardiac surgeon) are consecutively included in the study.

Two groups of patients are defined:

* Patients with cardiogenic shock treated by medical treatement

* Patients with cardiogenic shock treated by TCS (extracorporeal circulatory life support and/or Impella).

The main objective is to compare mortality between the 2 groups. Secondary objectives are ICU follow-up characteristics and quality of life questionnaire at day 180.

Statistical analysis will include a propensity-matched method to compare the groups to avoid confounding factors. The number of necessary subjects (n=240, 120 in each group) was calculated assuming that TCS has a superiority of 20% in comparison with medical treatment in severe cardiogenic shock, with a study power of 80%, and an alpha risk of 5%.

Primary Outcome Measures

Name	Time	Method
Hospital Mortality	From inclusion day to day 180	Mortality rate in the 2 groups at the time of hospital discharge

Secondary Outcome Measures

Name	Time	Method
Short term mortality rate	From inclusion day to Intensive Care Unit (ICU) discharge or day 28 whichever came first	Mortality rate at day 28
Bleeding events	From inclusion day to ICU discharge or day 28 whichever came first	Incidence of red blood cell transfusion
ICU stays	From inclusion day to day 180	Length of stay in ICU (number of days)
Respiratory failure	From inclusion day to ICU discharge or day 28 whichever came first	Days of mechanical ventilation
Hospital stays	From inclusion day to day 180	Length of stay in hospital (number of days)
Long term mortality rate	From inclusion day to day 180	Mortality rate at day 180
Acute renal failure	From inclusion day to ICU discharge or day 28 whichever came first	Incidence of renal replacement therapy
Thromboembolic events	From inclusion day to ICU discharge or day 28 whichever came first	Incidence of stroke, peripheral or mesenteric ischemia
Quality of life score SF 36	From inclusion day to day 180	Quality of life, evaluated by the Short Form Survey scoring (SF36 score) using the RAND 36-Item Health Survey 1.0, which will be sent by mail at day 180 after inclusion.; The RAND 36-Item Health Survey (Version 1.0) taps eight health concepts: physical functioning, bodily pain, role limitations due to physical health problems, role limitations due to personal or emotional problems, emotional well-being, social functioning, energy/fatigue, and general health perceptions. It also includes a single item that provides an indication of perceived change in health. Each item is scored on a 0 to 100 range so that the lowest and highest possible scores are 0 and 100, respectively.
