Study of Variables Related to Cerebrovascular Accident in Patients with COVID-19: A Literature Review

The objective of this article is to provide a bibliographic survey on the relationship between COVID-19 and stroke through a systematic review conducted in national and international journals without temporal delimitation, using articles indexed in multidisciplinary and health databases. The databases investigated were: BVS, PubMed, ERIC, SciELO, Web of Science, and Sociological Abstracts. Among the studies found, 43 articles were selected. Some of these were then used to produce the "literature review" section. Since stroke and COVID-19 can present similar symptoms, diagnosing stroke can be more challenging in some cases, highlighting the need for further research on the subject. The studies show a relationship between the severity of the condition and the occurrence of vascular events, with a higher incidence observed in patients hospitalized in intensive care units (ICUs). Additionally, it is important to mention the significance of d-dimer levels in the patient, as it is a factor with high predictive value for thrombotic events. The challenges in improving diagnosis and treatment are primarily due to the difficulty in understanding the pathophysiology, triggering events, and research on the topic.
