Meta-analyses of observational studies report a 1.1-1.7% pooled risk of stroke among patients with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection requiring hospitalization, but consultations for stroke and reperfusion procedures have decreased during the outbreak that occurred during the first half of the year 2020. It is still unclear whether a true increase in the risk of stroke exists among patients with coronavirus disease 2019 (COVID-19). In-hospital ischemic stroke (IHIS) complicated the 0.04-0.06% of all admissions in the pre-COVID-19 era, but its incidence has not been assessed among inpatients with COVID-19. We aimed to compare IHIS incidence among patients with SARS-CoV-2 infection with that of inpatients with non-COVID-19 illnesses from the same outbreak period and from previous periods. ⋯ SARS-CoV-2 outbreak was associated with an increase in the incidence of IHIS when compared with inpatients from a historical cohort. Viral infection itself may be related to the increased risk of IHIS among patients with COVID-19, but in view of our results from the 20NCC, it is likely that other factors, such as hospital saturation and overwhelming of health systems, may have played a role in the increased frequency of IHIS.
