Abstract 4125334: Disparities In Clinical And Demographic Outcomes Of Non-Acute Myocardial Infarction-Associated Cardiogenic Shock In African American Vs. Non-African American Patients: An Analysis From The National Inpatient Sample Database

Background: Limited knowledge exists regarding non-acute myocardial infarction-associated cardiogenic shock (nACS-CS) and its associated outcomes within the African American population. Aim: This investigation aimed to examine the clinical outcomes of nACS-CS in the African American population compared to the non-African-American population in the United States. Methods: The National Inpatient Sample (NIS) database was employed to identify hospitalizations with nACS-CS from 2018 to 2020. Patients were categorized as either African Americans or non-African Americans. Statistical analyses, including Chi-square and t-tests, were conducted using STATA version 18. Results: Out of 8,607 nACS-CS hospitalizations, 1,325 (15.4%) involved African Americans between 2018 and 2020 (Figure 1a). African American patients with nACS-CS tended to be younger (60.9±16.6 vs. 65.8±16.7 years; p < 0.05). Moreover, the length of stay for this cohort was notably longer (16.2±0.75 vs. 14.8±0.32 days; p < 0.05). The demographic age group affected by cardiogenic shock exhibited a decreasing trend as time progressed up to 2020 (p-trend<0.05; Figure 1b). The mean hospital charges were also higher for the African American cohort (p<0.05). In-hospital mortality also showed a progressive increase among African Americans over time (p<0.05). Conclusion: Among African American patients with nACS-CS, there is an escalating burden on healthcare, evidenced by a progressively younger demographic being affected over time, coupled with worsening rates of in-hospital mortality. Furthermore, there is a higher mean cost of hospitalization and a prolonged length of stay compared to their non-African American counterparts.
