【Abstract】ObjectiveTo explore the value of ASTRAL scale to assess the prognosis of posterior circulation acute cerebral infarction. MethodsA total of 211 patients with posterior circulation acute cerebral infarction were enrolled as the research objects, at 24 hours after admission, patients were given ASTRAL score, and were divided into high score group and low score group according to ASTRAL score; on 30 days after onset, patients were given mRS score to predict the prognosis, and were divided into favorable prognosis group and unfavorable prognosis group according to mRS score. The ASTRAL scores were compared between favorable prognosis group and unfavorable prognosis group, and the incidence of adverse reactions were compared between high score group (ASTRAL scores≥19) and low score group (ASTRAL scores＜19)，the relationship between ASTRAL scores and prognosis was analyzed. ResultsAmong 200 cases patients, 161 cases had favorable prognosis, and 39 cases had unfavorable prognosis; the ASTRAL scores in the favorable prognosis group was significantly lower than those in the unfavorable prognosis group (P＜0.05); the higher the ASTRAL score was, the higher the incidence of adverse reactions was (P＜0.05); the incidence of adverse reactions in the high score group was significantly higher than that in the low score group (P＜0.05). ConclusionsASTRAL scale is simple and easy application, the patients information that the scale need collects easily, and is no need to use complex formulas, doctors can assess the prognosis of patients quickly,which has a certain appraisal value for the prognosis of patients with posterior circulation acute cerebral infarction.
