踝臂指数(ABI)是评估下肢血液循环不良的指标。动脉粥样硬化可累及全身多处动脉,踝臂指数能反映全身其他动脉的粥样硬化程度。近年研究发现脑卒中发病的危险因素有很多,踝臂指数与颅内动脉粥样硬化程度关系密切,但踝臂指数可作为预测脑卒中患病率和病死率的重要因子之一。在此综述踝臂指数与缺血性脑血管病的关系。
Ankle brachial index (ABI) is an indicator of poor blood circulation in the lower limbs. Atherosclerosis can affect multiple arteries throughout the body. The ankle-brachial index reflects the degree of atherosclerosis in other arteries throughout the body. Recent studies have found that there are many risk factors for stroke. Ankle-brachial index is closely related to the degree of intracranial atherosclerosis. However, ankle-brachial index can be used as one of the important factors in predicting stroke morbidity and mortality. This article reviews the relationship between ankle brachial index and ischemic cerebrovascular disease.
