Evaluation of ABCD2 score during the development of stroke in COVID-19 patients diagnosed with transient ischemic attack in the emergency department.
Journal of Stroke and Cerebrovascular Diseases : the Official Journal of National Stroke Association 2022 December 3
BACKGROUND: The aim of the present study is to reveal the association between the risk of stroke using ABCD2 score and COVID-19 in patients who presented to our emergency department during the pandemic and were diagnosed with TIA.
METHODS: According to the recommendations of the European Stroke Association, patients with an ABCD2 score of <4 were classified as low-risk, and patients with an ABCD2 score of ≥4 were classified as high-risk. Within 90 days of the patient's admission to the emergency room, the development of stroke was tracked and recorded on the system.
RESULTS: Stroke occurred in 35.78% of the patients. Regarding COVID-19, 75.34% of stroke patients were positive for COVID-19 and 65.75% had COVID-19 compatible pneumonia on 'thoracic CT'. Regarding mortality, 16.4% of the patients who were positive for COVID-19 and developed a stroke died. The presence of COVID-19 compatible pneumonia on thorax CT, PCR test result and ABCD2 score were determined as independent risk factors for the development of stroke. According to the PCR test results, the probability of having a stroke decreases 0.283 times in patients who are negative for COVID-19. According to the PCR test results, the probability of having a stroke increased 2.7 times in COVID-19 positive patients.
CONCLUSIONS: Adding the presence of COVID-19 and the presence of COVID-19 pneumonia to the ABCD2 score, based on the information about the increased risk of stroke in TIA patients, improves the predictive power of the score. More studies are needed in this regard.
