Abstract
ObjectiveThe purpose of this study was to determine whether increased alkaline phosphatase (ALP) was associated with early neurological deterioration (END) in patients with atherothrombotic brain infarction (ATBI) attributable to intracranial atherosclerosis (ICAS) or not.MethodsWe analyzed data derived from 70 patients (47 men; mean age, 72.4 ± 12.8 years) with symptomatic ICAS who were admitted within 3 days of ATBI onset between April 2013 and December 2018. We defined END as an increase of ≥2 in the National Institutes of Health Stroke Scale scores during the first 72 h of hospitalization.ResultsEleven (15.7%) patients had END. Serum ALP levels on admission were significantly higher among patients with, than without END (median [interquartile range], 296 [233–338] vs. 216 [187–262] U/L, p = .0081).ConclusionIncreased serum ALP levels on admission may be able to predict developing END in patients with symptomatic ICAS.
