中老年高血压患者动态血压与脑卒中的关系

RELATIONSHIP OF AMBULATORY BLOOD PRESSURE AND STROKE IN ELDERLY HYPERTENSIVE PATIENTS

目的探讨中老年高血压患者动态血压与脑卒中的关系。方法采用２４ｈ动态血压监测（ＡＢＰＭ）技术对４０例中、老年高血压并发脑卒中患者的２４ｈ平均血压、日间和夜间血压、血压负荷及血压的昼夜节律进行观察，并与４０例单纯高血压病患者进行对照。结果脑卒中组血压昼夜节律消失者显著高于对照组，夜间血压水平和收缩压负荷也有显著升高，而２４ｈ平均血压、日间血压和舒张压负荷两组间差异无显著性。结论①血压昼夜节律状况、夜间血压水平和收缩压负荷对中、老年高血压患者发生脑卒中起重要作用；

ObjectiveTo analy relationship of ambulatory blood pressure (ABP) and stroke in elderly hypertensive patients.MethodsMean blood pressure in 24 hours,daytime blood pressure,nighttime blood pressure,load of blood pressure and circadian of blood pressure were observed by ABP monitoring (ABPM) in 40 middle or old aged patients with hypertension,and compared with 40 cases of hypertension.ResultsNumber of patients with blood pressure circadian lost in the stroke group was significantly higher than that in the control group,and level of blood pressure at nighttime and load of systolic blood pressure showed the same changes.Conclusion①Circadian of blood pressure,level of blood pressure at nighttime and load of systolic blood pressure play an important role in the development of stroke.②ABPM is of important value in the assessment of prognosis and guidance of treatment in patient with hypertension.
