Outcomes and Risk Factors for Cardiovascular Events in Hospitalized COVID-19 Patients
2021
Objective To analyze outcomes and risk factors of cardiovascular events in a metropolitan COVID-19 database, and to perform a subgroup analysis in African American populations to determine whether outcomes and risk factors are influenced by race Design Retrospective cohort analysis from March 9, 2020 to June 20, 2020 Setting Population-based study in Louisville, KY, USA Participants 700 adult inpatients hospitalized with COVID-19 Interventions N/A Measurements and Main Results: Our cohort consisted of 126 patients (18%) with cardiovascular events and 574 patients without cardiovascular events Patients with cardiovascular events had a much higher mortality rate than those without cardiovascular events (45 2% vs 8 7%, p<0 001) There was no difference between African Americans and Whites regarding mortality (43 9% vs 46 3%, p=1) and length of stay for survivors (11 days vs 9 5 days, p=0 301) Multiple logistics regression analysis suggested that male, race, lower SaO2/FiO2, higher serum potassium, lower serum albumin, and number of cardiovascular co-morbidities were highly associated with the occurrence of cardiovascular events in COVID-19 patients Lower serum albumin and neoplastic/immune compromised diseases were highly associated with cardiovascular events for African American COVID-19 patients SaO2/FiO2 ratio and cardiovascular comorbidity count were significantly associated with cardiovascular events in white patients Conclusions : Cardiovascular events were prevalent and associated with worse outcomes in hospitalized patients with COVID-19 Outcomes of cardiovascular events in African American and white COVID-19 patients were similar after propensity score matching analysis There were common and unique risk factors for cardiovascular events in African American COVID-19 patients when compared with white patients
