目的 :探索高原地区脑血管病的患病率及其危险因素。方法 :分析我院 1 998年— 2 0 0 3年间 1 876例脑卒中病人的临床资料 ,并利用SPSS统计软件包进行频数和logistic回归等项目分析。结果 :脑出血、蛛网膜下腔出血、脑梗塞和TIA的患病率分别为 32 .2 % ,4 .5 % ,4 1 .7%和2 1 .6 %。影响脑卒中发生的相关危险因素有 :高血压、年龄、性别、血红蛋白、红细胞压积、胆固醇和冠心病、糖尿病 (B =- 0 .6 6 0 ,B =0 .0 1 3,B =- 0 .4 6 2 ,B =- 0 .0 1 1 ,B =- 0 .2 86 ,B =- 0 .1 91 ,B =- 0 4 2 6 ,B =- 0 .30 7) ,其中血红蛋白和红细胞压积的水平都较平原地区的值高。结论 :高原地区脑血管病的患病率及其危险因素在主要指标方面与现有报道基本一致 ,但也有其高海拔的特点 ,Hb和Hct可能在高原脑卒中发生方面起着重要的作用
Objective: To explore the prevalence and risk factors of cerebrovascular disease in the plateau area. Methods: The clinical data of 1 876 stroke patients in our hospital from 1998 to 2003 were analyzed. SPSS statistical package was used to analyze frequency and logistic regression. Results: The prevalence of cerebral hemorrhage, subarachnoid hemorrhage, cerebral infarction and TIA were 32.2%, 4.5%, 41.7% and 21.6% respectively. The risk factors influencing stroke include hypertension, age, sex, hemoglobin, hematocrit, cholesterol and coronary heart disease, diabetes mellitus (B = -0.686, B = 0.013, B = 0 .4 6 2, B = - 0 .0 1 1, B = - 0 .2 86, B = - 0 .1 91, B = - 0 4 2 6, B = - 0 .30 7), where hemoglobin And hematocrit levels are higher than the value of the plain. Conclusion: The prevalence and risk factors of cerebrovascular disease in the plateau area are basically the same as those in the existing reports, but also have the characteristics of high altitude. Hb and Hct may play an important role in the occurrence of stroke in the plateau
