Anterior and posterior circulation infarction image score（APCIIS），a novel approach to evaluate the prognosis of patients with acute ischemic stroke

Abstract:

Objective Development and validation of a novel acute ischemic stroke（AIS） scoring system： Anterior and posterior circulation infarction image score（APCIIS）.Methods Retrospective analysis of clinical data from 163 patients with acute ischemic stroke admitted to the First Affiliated Hospital of Chongqing Medical University from 2020/6 to 2021/6. The patients were divided into anterior circulation AIS group（n=109） and posterior circulation AIS group（n=54）. Univariate and multivariate analyses were performed to identify risk factors affecting the prognosis of patients with AIS. Using the Clot Burden Score（CBS） and the Basilar Artery on Computed Tomography Angiography score（BATMAN） as references，receiver operating characteristic（ROC） curves were plotted to analyze the predictive value of the novel scoring system（APCIIS） for prognosis assessment.Results In the anterior circulation AIS group，although the prognostic value of APCIIS was not superior to CBS，it demonstrated relatively higher sensitivity of 86.8%，specificity of 90.1%，and an area under the curve of 0.939. In the posterior circulation AIS group，APCIIS showed better prognostic value than the BATMAN score.Conclusion APCIIS is a convenient and reliable method for predicting the prognosis of patients with AIS.
