RESUMO
BACKGROUND AND OBJECTIVES: Past history of stroke has been associated with an increased risk of a new ischemic stroke. Several studies have indicated increased prevalence of strokes among coronavirus patients. However, the role of past history of stroke in COVID19 patients is still unclear. The purpose of this systematic review is to evaluate and summarize the level of evidence on past history of stroke in COVID19 patients. METHODS: A systematic review was performed according to the PRISMA guidelines was performed in PubMed, Embase, EBSCO Host, Scopus, Science Direct, Medline, and LILACS. Eligibility criteria: We evaluated studies including patients with diagnosis of COVID 19 and a past history of stroke. Risk of bias: was evaluated with the Newcastle- Ottawa Scale (NOS) and experimental studies were evaluated using the ROBINS-I scale. RESULTS: Seven articles out of the total 213 articles were evaluated and included, involving 3244 patients with SARS VOC 2 Disease (COVID19) of which 198 had a history of cerebrovascular disease. Meta-analysis of the data was performed, observing an increase in mortality in patients with a history of cerebrovascular disease compared to those with different comorbidities or those without underlying pathology (OR 2.78 95 % CI [1.42-5.46] pâ¯=â¯0.007; I2â¯=â¯49 %) showing adequate heterogeneity. The presence of publication bias was evaluated using the Egger test in a funnel plot, showing adequate. Asymmetry, indicating that there is no publication bias; however, due to the low number of included studies, we could not rule out or confirm the presence of bias. CONCLUSIONS: The history of cerebrovascular disease was associated with a 2.78-fold increased risk of mortality compared to patients with other comorbidities or without underlying pathologies.
