Abstract

Aims: Data on cardiogenic shock (CS) in autoimmune diseases (AID) is limited. Our study aims to evaluate in-hospital outcomes of CS in hospitalized patients with underlying AID compared with patients without AID.

Methods: The National Inpatient Sample (NIS) database years 2011-17 was used to identify hospitalizations for CS. We retrospectively compared in-hospital outcomes of CS in patients with underlying AID versus non-AID.

Results: Of 863,239 patients diagnosed with CS, 23,127 (2.7%) had underlying AID. The AID population was older with more women and African American patients (P < 0.001 for all). There was a significant increase in in-hospital mortality in patients with AID vs non-AID that persisted after adjustment for demographics, comorbidities, insurance, socioeconomic status and hospital characteristics (38.3% vs 36.3%, aOR 1.06; 95% CI: 1.02-1.09, P = 0.001). Patients with AID had a lower rate of respiratory complications (11.5% vs 13.1%), acute stroke (6.0% vs 6.8%), use of mechanical circulatory support (12.0% vs 14.5%) and discharge to an outside facility (29.1% vs 28.8%) (P ≤ 0.001 for all). Using multivariable logistic regression, we identified female gender, Native American ethnicity, heart failure, coagulopathy, pulmonary circulation disorders, metastatic cancer, and fluid and electrolytes disorders as independent predictors of mortality in patients with AID who were diagnosed with CS.

Conclusion: Patients with AID hospitalized with CS have increased mortality which may be related to their underlying disease process and lack of effective disease-directed therapy for CS related to AID.
