Abstract Body: Objectives
A rapid and severe increase in blood pressure resulting in new or progressive end-organ damage is defined as a hypertensive emergency. Our study sought to estimate the clinical outcomes of black and white patients admitted for hypertensive emergency.

Methods
Using the National Inpatient Sample Database of 2020 (NIS), retrospective data of black and white patients who were admitted for hypertensive emergency were identified using ICD-10 codes. Outcomes were in-hospital mortality, cerebrovascular accident (CVA), acute kidney injury (AKI), myocardial infarction (MI), pulmonary edema, acute hypoxic respiratory failure, length of hospital stay, and total hospital charges.

Results
A total of 59690 patients were admitted for hypertensive emergency. 80.6% of patients were either black or white. Black patients were younger (54 years, 95% CI 54 – 55 VS 65 years, 95% CI 65 – 65) when compared to white patients. There were no statistically significant differences in inpatient mortality (p=0.2345), myocardial infarction (p=0.8618), and pulmonary edema (p=0.8835). Black patients had increased acute kidney injury (p<0.0001), acute hypoxic respiratory failure (p=0.0014), length of hospital stays (4 days, 95% CI 4 – 5 VS 3 days, 95% CI 3 – 4), and total hospital charges ($47,132.68, 95% CI $44,808.58 - $49,456.79 VS $43,882.58, 95% CI $42,394.76 - $45,370.39). White patients had increased cerebrovascular accident (p<0.0001) when compared to black patients.

Conclusion
Per this study, there was no difference in in-hospital mortality between black and white patients admitted for hypertensive emergency. Black patients had increased AKI, acute hypoxic respiratory failure, length of hospital stays, and charges.
