March 25, 2026

Association between pre-existing heart failure and in-hospital outcomes and management in admissions with cardiogenic shock

Key Result

Preexisting heart failure in patients admitted with cardiogenic shock is associated with lower in-hospital mortality and higher resource utilization.

Key Points

The study investigates the relationship between pre-existing heart failure and outcomes in patients with cardiogenic shock during hospital admissions.
Analyzed patient admissions with cardiogenic shock and pre-existing heart failure
Compared in-hospital mortality and resource utilization
Examined the need for tailored management strategies
Patients with pre-existing heart failure had lower in-hospital mortality rates
Higher resource utilization was noted in these patients
The findings suggest specific management strategies may be beneficial for this patient group

Structured PICO

Does pre-existing heart failure affect in-hospital mortality and resource utilization in admissions with cardiogenic shock?

Abstract

Preexisting HF is associated with a distinct CS phenotype, including lower in-hospital mortality and higher resource utilization, highlighting the need for phenotype-specific strategies and refined risk models in CS management.
