目的:通过测量踝臂指数(ankle-brachial index,ABI)评价我国缺血性卒中(ischaemic stroke,IS)患者下肢外周动脉病(Peripheral arterial disease,PAD)的患病情况。方法:对入院的423例IS患者进行踝臂指数测定,并进行资料收集和统计学处理。结果:423例缺血性卒中患者中150例合并下肢外周动脉病(平均ABI 0.64),其中只有11例(7.3％)患者得到了明确的诊断。PAD组与非PAD组患者相比,年龄(P=0.000)和糖尿病史(P=0.001)有统计学意义,而吸烟史(P=0.154),高血压病史(P=0.179)和血脂异常(P=0.383)无统计学意义。结论:通过测量ABI确诊下肢PAD简便易行;缺血性卒中患者易合并下肢PAD;缺血性卒中合并下肢PAD多见于高龄和糖尿病患者。
OBJECTIVE: To evaluate the prevalence of peripheral arterial disease (PAD) in the lower limbs of ischemic stroke patients in China by measuring the ankle-brachial index (ABI). Methods: Ankle brachial index was measured in 423 IS patients admitted to hospital and data collection and statistical analysis were performed. Results: Of the 423 ischemic stroke patients, 150 had peripheral arterial disease of the lower extremities (mean ABI 0.64), of whom only 11 (7.3%) had a definite diagnosis. There were significant differences in age (P = 0.000) and diabetes mellitus (P = 0.001) between the PAD group and non-PAD group, while smoking history (P = 0.154), history of hypertension (P = 0.179) and dyslipidemia P = 0.383) was not statistically significant. Conclusions: The diagnosis of lower extremity PAD by measuring ABI is simple and easy. In patients with ischemic stroke, lower extremity PAD is easy to be incorporated. PAD in ischemic stroke complicated with lower extremity is more common in elderly and diabetic patients.
