缺血性卒中患者踝臂指数与颅内动脉狭窄数量的关系

Relationship between Ankle Brachial Index and Number of Intracerebral Artery Stenosis in Patients with Ischemic Stroke

目的探讨缺血性脑卒中患者踝臂指数（ABI）与颅内动脉狭窄支数的相关性。方法测量314例行脑血管造影的缺血性卒中患者的ABI值，并收集其相关临床资料。结果ABI异常、年龄与缺血性卒中患者颅内动脉狭窄数量有关。ABI值与患者具备的危险因素（高血压、糖尿病、冠心病及缺血性卒中史）数量之间存在负相关性，两者之间存在线性趋势（χ2=36．35，P〈0．001）。ABI值与狭窄血管数量之间存在负相关性，两者之间存在线性趋势。结论缺血性脑卒中患者ABI值与颅内动脉狭窄数量具有相关性。

Objective To investigate the relationship of ankle brachial index and the number of intraeranial artery stenosis. Methods Ankle brachial index were measured in 314 patients with ischemie cerebrovascular disease received cerebral angiograpathy. Their data including general information and medical history were collected. Results Abnormality of ankle brachial index and age were associated with the number of intracranial artery stenosis in pa- tients with isehemic stroke. Ankle brachial index was negative correlation with the number of risk factors（ hyperten- tionJdiabetes/coronary heart disease/isehemic stroke history）（ r, = -0. 292,P 〈 0. 001 ）. Linear trend analysis showed linear trend between them（χ2 = 36. 35 ,P 〈 0. 001 ）. Ankle brachial index was negative correlation with the number of intracranial artery stenosis （ rs = - 0.161, P = 0. 004 ）. Trend analysis showed linear trend between them （χ2 = 6. 53, P = 0.01 ）. Conclusion Ankle brachial index was associated with the number of intracerebral artery stenosis.
