目的研究踝臂指数(ABI)与缺血性脑卒中患者颈动脉内膜中层厚度(IMT)、颈动脉硬化斑块程度的相关性,从而探讨ABI与缺血性脑卒中动脉硬化程度的关系。方法对200例缺血性脑卒中患者行ABI测量,同时行IMT及颈动脉斑块的检查,分析ABI与IMT、斑块程度的关系。结果 IMT与ABI呈高度负相关,斑块程度2级以上,ABI明显降低。结论 ABI可较好地反映颈动脉内膜中层厚度情况,对缺血性脑卒中动脉硬化程度的评价具有一定意义。
Objective To study the relationship between ankle-brachial index (ABI) and carotid intima-media thickness (IMT) and carotid atherosclerotic plaque in patients with ischemic stroke, and to explore the relationship between ABI and the degree of atherosclerosis in ischemic stroke. Methods A total of 200 ischemic stroke patients underwent ABI measurement. Meanwhile, IMT and carotid artery plaque were examined. The relationship between ABI and IMT and plaque was analyzed. Results IMT and ABI were highly negative correlation, plaque level above 2, ABI decreased significantly. Conclusion ABI can better reflect the intima-media thickness of carotid artery, which is of certain significance for evaluating the degree of atherosclerosis in ischemic stroke.
