Fig. 1 — Potential mechanisms of ischemic stroke in patients with COVID-19. While COVID-19-related systemic and cardiovascular alterations could potentially promote all types of ischemic stroke, the attributable risk is expected to be greater for Other and CE subtypes (larger arrows). LAA, large artery atherosclerosis; CE, cardiac embolism; SAO, small artery occlusion; Other, other uncommon causes of stroke; Undetermined, undetermined causes of stroke; DVT, deep venous thrombosis. It should be noted that in COVID-19, many large artery occlusions may not be due to atherosclerosis but to embolization (from an intracardiac thrombus, or paradoxical emboli from deep vein thrombosis).
