广西壮族与汉族脑梗死患者脑血管狭窄分布特征及影响因素

目的探讨广西壮、汉族脑梗死患者脑血管狭窄的分布特征及影响因素。方法对广西地区975例脑梗死患者行数字减影血管造影术(DSA)检查,按民族分为壮族组328例和汉族组647例,比较2组患者脑血管狭窄部位分布特点、狭窄程度、常规危险因素,采用logistic回归多因素分析。结果壮族组椎动脉颅内段狭窄发生率和脑血管重度狭窄率明显高于汉族组,差异有统计学意义(χ~2=4.833,P<0.05;χ~2=10.766,P<0.05)。同型半胱氨酸、年龄、民族、吸烟史、高血压等因素为脑血管重度狭窄的独立危险因素,其中同型半胱氨酸、年龄、吸烟史为汉族脑血管重度狭窄的独立危险因素,年龄、高血压为壮族脑血管重度狭窄的独立危险因素。结论壮族脑梗死患者脑血管重度狭窄率高于汉族患者,控制高血压是降低壮族患者脑血管狭窄风险的预防措施之一。

Distribution of cerebral vascular stenosis and influencing factors in Zhuang and Han patients with CI in Guangxi province

Objective To study the distribution characteristics of cerebral vascular stenosis and influencing factors in Zhuang and Han patients with cerebral infarction in Guangxi province.Methods 975 patients with cerebral infarction were examined by DSA.According to nationality,they were divided into two groups;Zhuang group including 328 patients and Han group including 647 patients.The distribution characteristics of cerebral vascular stenosis,the degree of stenosis and conventional risk factors were compared between the two groups.Logistic regression was used for multifactor analysis.Results The incidence of intracranial vertebral artery stenosis and rate of severe cerebral vascular stenosis in Zhuang group were significantly higher than those in Han group (x~2=4.833,P <0.05;x~2=10.766,P<0.05).The independent risk factors for severe stenosis in all patients included Hcy,age,nationality,smoking history and hypertension.Among the two groups,Hcy,age and smoking history were the independent risk factors for Han nationality,age and hypertension were the independent risk factors for Zhuang nationality.Conclusion The incidence of severe cerebral vascular stenosis in Zhuang patients with cerebral infarction is higher than that in Han patients.Control of blood pressure is one of the important preventive measures for decreasing the risk of cerebral vascular stenosis in Zhuang nationality.
