Racial, ethnic and sex disparity in acute heart failure patients with COVID-19: A nationwide analysis

Abstract

Background: Patients with acute heart failure (AHF) exacerbation are susceptible to complications in the setting of COVID-19 infection. Data regarding the racial/ethnic and sex disparities in patients with AHF and COVID-19 remains limited. Objective: We aim to evaluate the impact of race, ethnicity, and sex on the in-hospital outcomes of AHF with COVID-19 infection using the data from the National Inpatient Sample (NIS). Methods: We extracted data from the NIS (2020) by using ICD-10-CM to identify all hospitalizations with a diagnosis of AHF and COVID-19 in the year 2020. The associations between sex, race/ethnicity, and outcomes were examined using a multivariable logistic regression model. Results: We identified a total of 158,530 weighted AHF hospitalizations with COVID-19 infection in 2020. The majority were White (63.9 %), 23.3 % were Black race, and 12.8 % were of Hispanic ethnicity, mostly males (n = 84,870 [53.5 %]). After adjustment, the odds of in-hospital mortality were lowest in White females (aOR 0.83, [0.78–0.98]) and highest in Hispanic males (aOR 1.27 [1.13–1.42]) compared with White males. Overall, the odds of cardiac arrest (aOR 1.54 [1.27–1.85]) and AKI (aOR 1.36 [1.26–1.47] were higher, while odds for procedural interventions such as PCI (aOR 0.23 [0.10–0.55]), and placement on a ventilator (aOR 0.85 [0.75–0.97]) were lower among Black males in comparison to White males. Conclusion: Male sex was associated with a higher risk of in-hospital mortality in white and black racial groups, while no such association was noted in the Hispanic group. Hispanic males had the highest odds of death compared with White males.
