Abstract 17276: Impact of Cardiovascular Comorbidities on COVID-19 Infection Risk

Introduction: A disproportionate amount of COVID-19 infections has occurred in minority populations and in individuals with comorbid disease. We sought to evaluate the impact of patient demographics, cardiovascular disease (CVD), and known CVD risk factors on the incidence of COVID-19 infection. Methods: Between April 1st to May 1st, 2020, 844 adult patients (mean age 51.4±17.7 years, mean BMI 29.6±8.3, 50% male) admitted for any reason and tested for COVID-19 based on CDC criteria were studied in this large, metropolitan, single-center retrospective cohort analysis. Bivariate and multivariate analysis between patient demographics, CVD, and CVD risk factors with COVID-19 were evaluated. The nonlinear effects of age on COVID-19 test results were further analyzed. Results: Prevalence of COVID-19 was 21.7%. African Americans, Latinos, and Caucasian were 463(55%), 216(25%), 165(20%) respectively. Unadjusted, diabetes mellitus (DM) was significantly related with the COVID-19 positivity (OR 1.83, 95% CI 1.30-2.58, P=0.0005), but age adjusted DM was insignificant (OR 1.35, 95% CI 0.93-1.97, P=0.12). Similar results were found with other CVD risk factors (see Tables 1,2). Stratified analysis by age groups (18-40 years, ≥40 years), DM in the younger age group was the most significant risk factor for the COVID-19 positivity (OR 4.52, 95% CI 1.95-10.52, P=0.0002) but not in older inpatients (OR 1.23, 95% CI 0.85-1.81, P=0.2763). In the older age group, Latinos were significantly higher risk for COVID-19 compared to Caucasian (OR 2.27, 95% CI 1.26-4.07, P=0.005). Conclusions: Increased resources for testing in younger individuals with DM and the Hispanic population may be merited.
