Prognostic performance of the SCAI shock classification at admission and during ICU treatment: A retrospective, observational cohort study.

Background: Cardiogenic shock (CS) is characterized by high mortality and requires accurate prognostic tools to predict outcomes and guide treatment. The Society for Cardiovascular Angiography and Interventions (SCAI) shock classification indicates shock severity and can be used for outcome prediction.

Objective: Here, we compare the prognostic performance of SCAI shock classification determined on admission and during intensive care unit (ICU) stay.
