Background:
Patients with heart failure with reduced ejection fraction (HFrEF) are at increased risk for sepsis/septic shock.
Method:
A retrospective study was conducted using the Nationwide Readmission Database (2016-2020). Adult patients admitted with sepsis or septic shock were identified and stratified based on the presence of underlying HFrEF. Multivariable logistic regression assessed the association between HFrEF and in-hospital mortality, 90-day readmission, and other complications.
Results:
Among 7,326,930 sepsis/septic shock admissions, 6.2 % had HFrEF. HFrEF patients had higher in-hospital mortality (17 % vs. 9.6 %, p < 0.01) and 90-day readmission rates (30.2 % vs. 22.5 %, p < 0.01) compared to those without HFrEF. These differences persisted after adjustment with increased risk of in-hospital mortality (aOR 1.40, 95 %CI 1.38-1.42) and 90-day readmission (aOR 1.15, 95 %CI 1.13-1.16).
Conclusion:
HFrEF patients admitted with sepsis/septic shock have significantly higher rates of in-hospital mortality, complications, and 90-day readmissions compared to those without HFrEF.
