Cardioembolic stroke, the most common subtype of stroke in COVID 19: A single center experience from Isfahan, Iran

Abstract

Background: Some studies showed the cerebrovascular manifestation in patients with recently pandemic coronavirus 2 named the coronavirus disease 2019 (COVID-19). However, there are rare reports about stroke subtypes in these patients. Here, we reported the stroke subtype in patients with laboratory-confirmed diagnosis of COVID-19 and treated at our hospitals, which are located in Isfahan, Iran.Materials and Methods: This is a retrospective, observational case series. Data were collected from March 01, 2020, to May 20, 2020, at three designated special care centers for COVID-19 of Isfahan University of Medical Sciences. The study included 1188 consecutive hospitalized patients with laboratory-confirmed diagnosis of COVID-19.Results: Of 1188 COVID-19 patients, 7 (0.5) patients developed stroke. Five (0.4) had ischemic arterial stroke, 1 (0.08) hemorrhagic stroke and 1(0.08 ) cerebral venous and sinus thrombosis. Sixty percent of ischemic stroke were cardioembolic stroke (CE) and the rest 2 (40) were embolic stroke of undetermined source. Three male patients (40) had stroke as a presenting and admitted symptom of COVID-19. Four patients (57) had severe COVID-19.Conclusion: Stroke was an uncommon manifestation in COVID-19 patients. CE was a common subtype of stroke in COVID-19 patients in our centers.
