Relationship between Ankler-brachial Index and Extent of Intracranial Artery Stenosis / 中国康复理论与实践

ABSTRACT

@# ObjectiveTo evaluate the significance of ankler-brachial index (ABI) to predict the extent of intracranial artery stenosis in ischemic stroke patients. Methods243 ischemic stroke patients were enrolled, brain angiography were examined and all of the ABI and basic data were collected. ResultsABI≤0.9 was associated with a specificity of 84.6% and a sensitivity of 16.8% for predicting the presence of severe stenosis in intracranial artery. The area under receiver operating characteristic curve was (0.591±0.046) (P<0.05). ConclusionABI≤0.9 has a relative specificity and sensitivity for predicting the presence of severe stenosis of intracranial artery.
