ABSTRACT

Introduction:

Recent studies have shown patients with coronavirus disease 2019 (COVID-19) develop significant coagulopathy with thromboembolic complications including ischemic stroke. However, data are sparse regarding the clinical characteristics, stroke mechanism, and patient outcomes.

Methods:

We conducted a retrospective cohort study of consecutive patients with ischemic stroke who were hospitalized between March 2020 and June 2021, within at a Regional Medical Center serving three large counties in South Carolina. We further investigated clinical and demographic characteristics, stroke severity as measured by the National Institutes of Health Stroke Scale (NIHSS), and stroke subtype as measured by the TOAST (Trial of ORG 10172 in Acute Stroke Treatment) criteria among patients with COVID-19 who also suffered from an acute ischemic stroke.

Results:

During the study period, out of 1087 hospitalized patients with a diagnosis of COVID-19 infection, 18 patients (1.6%) had an imaging-proven ischemic stroke. Of these 18 patients, 10 (56%) were men, 16 were African-Americans (89%), 2 (11.1%) patients were <55 years of age. All patients had at least one known vascular risk factor. Cryptogenic stroke was more common in patients with COVID-19 (83%). The median time (days) from COVID-19 symptom onset to stroke symptom onset was 11 (IQR 10-28), while the median time from being tested positive for COVID-19 to stroke diagnosis was 10 (IQR 2-24). Our study sample had a median admission NIHSS score of 5 (IQR 3- 11) and a median peak D-dimer level of 2101 (IQR 1349 - 3213). Interestingly, 38% of these patients were already on therapeutic anticoagulation before the diagnosis of stroke. Patients with COVID-19 and stroke had an inpatient mortality rate of 11%. None of these patients met the criteria for IV-tPA treatment or thrombectomy.

Conclusion:

We observed a modest rate of ischemic stroke in hospitalized patients with COVID-19. Most strokes were cryptogenic, possibly secondary to coagulopathy associated with COVID-19 infection. Further studies are needed to guide management for stroke prevention in patients with COVID-19.
