Ischaemic strokes associated with COVID-19: is there a specific pattern?


SARS-Cov2 is responsible for COVID-19 that can cause severe respiratory illness, and which can be associated with ischaemic stroke (IS).1 The objectives of our comparative cross-sectional study were to describe the characteristics of consecutive patients with IS and COVID-19, to compare them to COVID-19-negative IS patients admitted within the same period and to attempt to identify a specific pattern of IS in COVID-19.


We conducted a comparative cross-sectional study at two tertiary stroke units, Pitié-Salpêtrière and Saint-Antoine Hospitals, between March 20 and April 20 2020. Cases and controls were all consecutive adult patients hospitalised for recent IS, confirmed on neuroimaging. Cases were diagnosed with COVID-19 if a nasopharyngeal reverse transcription (RT-PCR) test for SARS-CoV-2 (Allplex 2019-nCoV Assay, Seegene) was positive and/or if a chest CT-scan was typical for COVID-19. Exclusion criteria were diagnoses of transient ischaemic attack, haemorrhagic stroke or stroke secondary to cerebral venous thrombosis.
