Authors' conclusion

In HF-CS, kidney injury is associated with higher 30-day mortality, potentially mediated by bleeding and sepsis.

Study context

Population
Patients with heart failure-related cardiogenic shock (HF-CS), 2010–2021
Participants
1,010 patients
Exposure
Acute kidney injury (AKI) stages and severe renal dysfunction vs none
