Short term outcomes and resource utilization in de-novo versus acute on chronic heart failure related cardiogenic shock: a nationwide analysis

Our findings align with existing research, demonstrating higher in-hospital mortality in the DN-CS subgroup. After the index hospitalization, however, the CHF-CS cohort performed worse with higher all-cause readmission rate and readmission mortality. The study also underscores the need for further investigation into the underutilization of certain interventions and the observed trends in the management of these CS subgroups.
