Abstract: Background: COVID-19 infections have been shown to increase risk of major cardiovascular events. We aim to compare the incidence rate (IR) of all cardiovascular hospitalizations in Veterans hospitalized with COVID-19 with those hospitalized without COVID-19. Methods: This retrospective nationwide Veterans Health Administration (VHA) observational cohort study included hospitalized COVID-19 patients aged 18 years and older from January 2020 through January 2022 as the intervention cohort while the control cohort consisted of patients who were hospitalized for reasons other than COVID-19 without a positive COVID-19 test prior to or during the study duration. Propensity scores were utilized for 1:1 matching. The primary outcome included all cardiovascular. Results: The matched cohort included 50,805 patients in each group. Primary and secondary outcome results showed that incidence rates of all cardiovascular hospitalizations [90-day IRR 1.08 (95% CI 1.05-1.11), p<0.001; 180-day IRR 1.11 (95% CI 1.08-1.14), p<0.001] were significantly higher in the COVID-19 cohort as compared to the control group. No treatment modification was noted based on the predefined subgroups of age, sex, or Charlson comorbidity index. Conclusion: Veterans hospitalized with COVID-19 had higher rates of cardiovascular related hospitalization compared to those hospitalized without COVID-19. Further research is needed to assess the long-term effects of COVID-19 infection on cardiovascular health in individuals not hospitalized for COVID-19 to help illuminate any possible correlation between severity of illness and cardiovascular effects.
