COVID-19 and the incidence of post-infection ischemic stroke: An integrative literature review.

Abstract

SARS-CoV-2 is a virus that emerged in 2019, being responsible for causing a respiratory syndrome that was named COVID-19. The virus has a protein, called Spike protein, which interacts with ACE2, which are present in the respiratory tract and endothelial cells, causing inflammation, apoptosis and prothrombotic effects that activate the coagulation pathway. Thus, it is presumed that the hypercoagulable state of the virus and endothelial inflammation are related to the pathophysiology of post-infection ischemic stroke. The aim of this review was to analyze the pathophysiology and etiology of strokes associated with SARS-CoV-2 virus infection and their risk factors. A search for previous works was carried out on PubMed and VHL platforms, and a total of 26 scientific articles were included after applying inclusion and exclusion criteria. Through the studies analyzed, a correlation was observed between the increased incidence of stroke after infection with SARS-CoV-2, and the main risk factors present were arterial hypertension, atrial fibrillation, diabetes mellitus, dyslipidemia and heart failure. In conclusion, SARS-CoV-2 infection is related to the increased incidence of stroke, possibly due to its thrombotic and endothelial inflammatory mechanism.
