Abstract
ORTIZ, Mónica et al. Stroke and COVID-19: A review of observational studies published during the pandemic. Acta Neurol Colomb. [online]. 2020, vol.36, n.2, pp.63-74. ISSN 0120-8748. https://doi.org/10.22379/24224022280.
INTRODUCTION:
In March 2020, COVID-19 was declared a pandemic by the World Health Organization and cases of stroke related to the virus soon were reported.
OBJECTIVES:
To become aware of the experiences different parts of the world have encountered with stroke and COVID 19 in order to enhance our knowledge, improve recognition and response to patients in our clinical setting.
METHODS:
A review of the available observational studies was done using PubMed, Scopus and other sources of gray literature for the publications on stroke and COVID-19. Demographic data, time of stroke onset since the diagnosis of COVID-19, main radiological findings, lab tests and prognosis were identified.
RESULTS:
Eight studies were selected with 43 subjects who had ischemic stroke and SARS-CoV-2 infection. The average age was 67.4 years, being mostly men (58%). An important finding was the number of stroke cases with large vessel occlusion, with 22 of 31 cases reported (71%). The NIHSS median was 14.5 points, and 27.5% of subjects with stroke and COVID-19 died. The most frequent disease severity for COVID-19 was "severe", accounting for 58% of the cases. The onset of stroke after SARS-CoV-2 infection was 10.6 days on average. In the laboratories an elevation of fibrinogen (92%), D-Dimer (76%) and LDH (82%) were respectively identified. The most frequent treatment received for stroke were antiplatelet medications (51%), while reperfusion therapy was done in 30% of cases. Most patients presented to the hospital with typical symptoms of COVID-19 (93%), (7%) 3 patients did not have respiratory symptoms, however they presented with a decreased level of consciousness associated with stroke findings.
CONCLUSION:
Inflammation and hypercoagulability, both present during the infection by SARS-CoV-2, are probably related to the development of a stroke, which in this case could explain the large number of large vessel occlusions. Protected stroke code is a protocol that should be implemented in our region.
