Background: Cardiogenic shock (CS) is associated with high mortality. We report on a "Shock Team" approach of combined interdisciplinary expertise for decision making, expedited assessment, and treatment. Methods: We reviewed 100 patients admitted in CS over 52 months. Patients managed under a Code Shock Team protocol (n ¼ 64, treatment) from 2016 to 2019 were compared with standard care (n ¼ 36, control) from 2015 to 2016. The cohort was predominantly male (78% treatment, 67% control) with a median age of 55 years (interquartile range [IQR], 43-64) for treatment vs 64 years (IQR, 48-69) for control (P ¼ 0.01). New heart failure was more common in the treatment group: 61% vs 36%, P ¼ 0.02. Acute myocardial infarction comprised 13% of patients in CS. There were no significant differences between treatment and control in markers of clinical acuity, including median left ventricular ejection fraction (18% vs 20%), prevalence of R ESUM E Contexte : Le choc cardiog enique (CC) est associ e à une mortalit e elev ee. Nous d ecrivons une approche où la prise de d ecision, l' evaluation rapide des cas et le traitement sont confi es à une « equipe de choc » interdisciplinaire. M ethodologie : Nous avons examin e les cas de 100 patients hospitalis es en raison d'un CC sur une p eriode de 52 mois. Les patients pris en charge par une equipe interdisciplinaire selon un protocole d'intervention d eclench e par un code-choc (n ¼ 64, groupe trait e) de 2016 à 2019 ont et e compar es à des patients ayant reçu des soins courants (n ¼ 36, groupe t emoin) de 2015 à 2016. Les patients de la cohorte etaient majoritairement de sexe masculin (78 % dans le groupe trait e, 67 % dans le groupe t emoin) et l'âge m edian etait de 55 ans (intervalle interquartile [IIQ]: 43-64) au sein du groupe trait e par rapport à 64 ans (IIQ : 48-69) au sein du groupe t emoin (p ¼ 0,01). Les nou-Cardiogenic shock (CS) is defined as a low cardiac output state with end-organ hypoperfusion. 1 The etiology is broad and includes acute myocardial infarction (AMI), acute decompensated heart failure (ADHF) of preexisting cardiomyopathy, fulminant myocarditis, and tachyarrhythmia. 1 Clinical presentation is variable ranging from rapid hemodynamic deterioration over hours to a more insidious onset over days. Heterogeneity of etiology, presentation, and clinical trajectory have contributed to difficulties standardizing definitions for diagnosis, leading to delayed recognition, management variability, and uncertain optimal practice. Consequently, despite medical advances, clinical outcomes in CS remain poor with up to 50% in-hospital mortality reported in most series. 2,3 An increasing number of institutions are adopting a multidisciplinary team-based strategy for CS and have shown feasibility associated with improved outcomes. [4][5][6][7] In 2016, a Code Shock Team approach was implemented at our institution, which uses an emergent "Code" activation similar to other high-acuity, time-sensitive conditions such as ST-elevation myocardial infarction, cardiac arrest, and...
