Impact of Baseline Cardiogenic Shock Severity on Outcomes in Patients Treated With Impella Device.

ABSTRACT:

Background

Risk stratification of patients with cardiogenic shock (CS) is of considerable importance. We aimed to test the utility of the Society for Cardiovascular Angiography and Intervention shock staging system recently refined by the CS Working Group in an Asian population and to investigate its association with in-hospital adverse events.

Methods

From the Japanese nationwide registry of Impella, the patients with CS who successfully received Impella support between February 2020 and December 2023 were included and assigned to any stage according to the CS Working Group-refined Society for Cardiovascular Angiography and Intervention staging system. We set the primary end point as in-hospital death and explored it within each stage, with stage B as a reference.
