目的:探讨老年急性脑梗死患者脑动脉狭窄的分布及其危险因素。方法:对150例老年急性脑梗死患者及144例对照组人群进行经颅多普勒超声和血压、血脂、血糖、吸烟饮酒史、心脑血管病家族史进行收集。结果:研究组颅内动脉狭窄检出率(42.0%)高于对照组(13.9%)(P<0.05),颅内动脉狭窄分布为MCA 41.3%、TICA 31.7%、VA 14.3%、ACA 9.5%、BA 6.3%、PCA4.8%。血脂异常、长期吸烟、长期饮酒、高血压、糖尿病、心脑血管病家族史、胆红素、尿酸以及C反应蛋白与颅内动脉狭窄相关。结论:关注颅内动脉狭窄及其危险因素对老年急性脑梗死患者非常重要,控制危险因素是医务工作者的重要工作。
Objective: To investigate the distribution and risk factors of cerebral artery stenosis in elderly patients with acute cerebral infarction. Methods: A total of 150 elderly patients with acute cerebral infarction and 144 controls were enrolled in transcranial Doppler echocardiography and blood pressure, blood lipid, blood glucose, smoking and drinking history, and family history of cardiovascular and cerebrovascular diseases. Results: The detection rate of intracranial arterial stenosis was 42.0% in study group (13.9%) (P <0.05). The distribution of intracranial arterial stenosis was 41.3% in MCA, 31.7% in TICA, 14.3% in VA, 9.5% , BA 6.3%, PCA 4.8%. Dyslipidemia, long-term smoking, long-term alcohol consumption, hypertension, diabetes, family history of cardiovascular and cerebrovascular disease, bilirubin, uric acid and C-reactive protein were associated with intracranial arterial stenosis. Conclusion: Concerned about intracranial arterial stenosis and its risk factors are very important for elderly patients with acute cerebral infarction. To control risk factors is an important task for medical workers.
