ABSTRACT
BackgroundCOVID-19 infection is associated with thrombotic events; however, this phenomenon is poorly understood. Few studies have reported the association between COVID-19 and stroke in the hospital setting. MethodsWe retrospectively reviewed and characterized all patients who presented to a single, quaternary medical center between March and December 2020 (N=603). COVID-19 positive patients who developed ischemic or hemorrhagic stroke were included in the analysis (N=66). This cohort was compared with patients who were COVID-19 negative at the time of stroke presentation in the same period (N=537). Statistical significance was evaluated using Pearsons Chi squared test with Yates continuity correction and linear model ANOVA. ResultsSixty-six patients had COVID-19 and Stroke. Of these patients, 22 (33.4%) patients initially presented with stroke and 44 (66.7%) initially presented with COVID-19. Patients who presented with COVID-19 and had a stroke during their hospitalization (COVID-first) had worse outcomes than patients presenting to the hospital with stroke whose COVID test became positive later in the hospitalization (stroke-first). Patients who presented with COVID-19 and had a stroke during their hospitalization had an increased rate of acute renal failure (48.9% vs 19.0%, p=0.021) and need for ventilation (60.0% vs 28.6%, p=0.017). Further, in the COVID-first cohort, the use of heparin prior to the stroke event was not associated with mortality or type of stroke (ischemic or hemorrhagic). ConclusionIn the early pandemic, patients with COVID-19 infection and stroke had a higher mortality rate compared to COVID-19 negative patients with stroke. Among patients with both COVID-19 and stroke, patients presenting with COVID-19 first had worse outcomes than patients presenting with stroke first. The use of heparin prior to the stroke event was not associated with mortality or type of stroke.
