Cardiogenic shock is a frequent reason for hospitalization in critical care units, with high mortality (50%). Several French registries have been created to improve knowledge of the prognostic factors of cardiogenic shock. In recent years, temporary mechanical circulatory support has become more important in cardiogenic shock. The monitoring of catecholamines is also performed with a global score: the vaso-inotropic score. The purpose of our study is to consider using these new data and techniques to create a cohort of cardiogenic shock within our critical care unit. This observational study is based on clinical, biological, and hemodynamic data recorded during the ICU stay of patients for cardiogenic shock. The primary endpoint is the relationship between the hemodynamic evolution of cardiogenic shock and in-hospital mortality.
