Racial Disparities in Mortality Associated With Acute Myocardial Infarction and COVID-19 in the United States: A Nationwide Analysis

Abstract

This study assessed the COVID-19 pandemic's impact on racial disparities in acute myocardial infarction (AMI) management and outcomes. We reviewed AMI patient management and outcomes in the pandemic's initial nine months, comparing COVID-19 and non-COVID-19 cases using 2020's National Inpatient Sample data. Our findings revealed that patients with concurrent AMI and COVID-19 had higher in-hospital mortality (aOR 3.19, 95% CI 2.63-3.88), increased mechanical ventilation (aOR 1.90, 95% CI 1.54-2.33), and higher initiation of hemodialysis (aOR 1.38, 95% CI 1.05-1.89) compared to those without COVID-19. Moreover, Black and Asian/Pacific Islander patients had higher in-hospital mortality than White patients, (aOR 2.13, 95% CI 1.35-3.59; aOR 3.41, 95% CI 1.5-8.37). Also, Black, Hispanic, and Asian/Pacific Islander patients showed higher odds of initiating hemodialysis (aOR 5.48, 95% CI 2.13-14.1; aOR 2.99, 95% CI 1.13-7.97; aOR 7.84, 95% CI 1.55-39.5), and were less likely to receive PCI for AMI (aOR 0.71, 95% CI 0.67-0.74; aOR 0.81, 95% CI 0.77-0.86; aOR 0.82, 95% CI 0.75-0.90). Black patients also showed less likelihood of undergoing CABG (aOR 0.55, 95% CI 0.49-0.61). Our study highlights elevated mortality and complications in COVID-19 AMI patients, emphasizing significant racial disparities. These findings underscore the pressing need for initiatives addressing healthcare disparities, enhancing access, and promoting culturally sensitive care to boost health equity.
