Incidence of Transient Ischemic Attack before and after the pandemic

Resumo

COVID-19 is an infectious disease caused by SARS-CoV-2. The most important clinical manifestation is the respiratory one, although, an increase in neurological features and cerebrovascular disorders have been reported as increased risk of stroke and transient ischemic attacks (TIA). This study aims to evaluate the change in the incidence of TIA regarding to the coronavirus pandemic context experienced in Brazil. This is a cross-sectional, quantitative epidemiological study, with analysis of data collected by the SUS Department of Informatics (DATASUS). In 2020 and 2021, there was a significant reduction in cases when compared to 2018 and 2019, with an average reduction of 15%. The average number of cases in the last two years analyzed was close to 18,261 cases. The region with the highest incidence of cases over the years analyzed was the Southeast region, representing 30,829 cases, followed by the South region with a total of 20,308 cases. North and Midwest were the least incident regions, representing 6,392 and 4,492 cases, respectively. Although there is an association between COVID-19 and an increase in the risk of cerebrovascular events, such as TIA, the number of cases did not increase in the years 2020 and 2021, which may reflect both underreporting and overload of the health care system during the pandemic.
