选择北京市崇文、西城两地自然人群共19546人,对年龄35岁以上者,整群随机调查5441人进行前瞻性观察.本组结果脑卒中四年累积发病者181例,CT检查114例,占63%,在混合性高血压和单纯收缩期型高血压患者中并发脑卒中者,出血性占81%,缺血性占68.8%(P<0.01).收缩期型高血压发生卒中者,老年组(年龄60岁以上)高于非老年组(P<0.01),收缩压的升高是引起老年人中风的重要危险因素.脑卒中CT分类,脑出血占33.3%;脑梗塞占60.5%,有29.2%正常血压者发生缺血性卒中.因此积极寻找血压之外密切相关的危险因素也是降低缺血性卒中不容忽视的重要环节.
A total of 19546 people were selected from natural populations in Chongwen and Xicheng of Beijing, and 5441 persons were randomized to prospective observation in a randomized cohort of 3541. The results of this study were 181 patients with four-year cumulative stroke, 114 with CT, Accounting for 63% of patients with mixed stroke and isolated systolic hypertension in patients with stroke, hemorrhage accounted for 81%, ischemic 68.8% (P <0.01) .Stroke-type hypertension stroke, The elderly group (over 60 years of age) was higher than the non-elderly group (P <0.01), systolic blood pressure is an important risk factor for stroke in the elderly.CT classification of stroke, cerebral hemorrhage accounted for 33.3%; cerebral infarction accounted for 60.5% , There are 29.2% of normal blood pressure in patients with ischemic stroke.Therefore, actively looking for blood pressure outside the closely related risk factors are also important steps to reduce ischemic stroke can not be ignored.
