踝臂指数的临床应用

踝臂指数（踝动脉与肱动脉收缩压的比值）是诊断外周动脉疾病的一种简单、非侵入性、可靠的方法。大量研究表明，低踝臂指数不仅是心脑血管病发病和死亡的独立预测因素，为系统性动脉硬化的重要指标。现着重阐述踝臂指数异常（〈0．9）与外周动脉病、心血管疾病、脑血管疾病、慢性肾功能衰竭等多种疾病之间的关系，旨在分析踝臂指数的临床应用价值，明确动脉粥样硬化为全身性疾病，以期在临床工作中更好地防治动脉粥样硬化性疾病。

Clinical Application of Ankle-brachial Index

The ankle-brachial index （ the ratio of ankle to brachial systolic blood pressure index） is a simple, non-invasive, and reliable method to access peripheral-arterial disease. Large-scale studies showed that, low ankle-brachial index is not only an independent predictor for cardio-cerebral vascular diseases and mortality, but also an important indicator of systemic atherosclerosis. The relationship of abnormal ankle-brachial index with those diseases, including peripheral arterial disease, cardiovascular disease, cerebrovascular disease and chronic renal failure are examined in this article. It is our purpose to analyze the clinical value of ankle-brachial index, and realize that atherosclerosis is a systemic disease in order to improve the prevention and cure of the disease.
