目的 探讨踝臂血压比值与脑梗死的关系。方法 研究对象为 2 0 0例脑梗死病例和 2 0 0例非脑梗死病例组成 ,二组年龄和性别相匹配 ,二组均采用袖带式自动血压计进行测量血压 ,分别测量左踝和左上臂的血压 3次 ,取其收缩压的平均值作为踝臂血压比值。结果 脑梗死组年龄 (63 .6± 1 2 .5)岁 ,对照组年龄 (64 .1± 1 3 .2 )岁 ,二组年龄之间差异无统计学意义。脑梗死组的踝臂血压比值为0 .92± 0 .0 7;对照组为 1 .1 0± 0 .0 6 ,二组踝臂血压比值差异有统计学意义。脑梗死组的踝臂血压比值 <0 .90的占 51 % ;而对照组的踝臂血压比值 <0 .90的占 4 % ,二组之间差异有统计学意义。结论 颈动脉狭窄和低的踝臂血压比值均被认为是全身动脉硬化疾病的标志 ,踝臂血压比值很容易测量 ,建议对存在脑动脉硬化的老年人如果踝臂血压比值 <0 .90应高度警惕脑梗死的发生 ,并应积极进行干预 ,从而降低脑梗死的发病率
Objective To investigate the relationship between ankle-brachial blood pressure ratio and cerebral infarction. Methods The subjects were 200 cases of cerebral infarction and 200 cases of non-cerebral infarction. The age and gender of the two groups were matched. The cuff-type automatic blood pressure monitor was used to measure the blood pressure. The left ankle and left upper left Arm blood pressure 3 times, whichever is the average systolic blood pressure as ankle-arm blood pressure ratio. Results The age of the infarction group was (63.6 ± 12.5) years old and the age of the control group (64.1 ± 132.2) years old. There was no significant difference between the two groups in age. The ratio of ankle-brachial blood pressure was 0.92 ± 0.0 7 in cerebral infarction group and 1.10 ± 0.60 in control group, and there was significant difference between the two groups in the ratio of ankle-brachial blood pressure. Cerebral infarction group, ankle-arm blood pressure ratio <0 .90 51%; while the control group ankle-arm blood pressure ratio <0 .90 of 4%, the difference between the two groups was statistically significant. Conclusions Carotid artery stenosis and low ratio of ankle-brachial blood pressure are both considered as markers of systemic arterial disease. The ratio of ankle-brachial blood pressure is easy to measure. It is recommended that for an elderly with cerebral arteriosclerosis, ankle-brachial blood pressure ratio <0 .90 should be highly Be alert to the occurrence of cerebral infarction, and should actively intervene to reduce the incidence of cerebral infarction
