目的探讨高血压脑出血与脑梗塞患者血压的昼夜变化规律。方法８２例高血压患者中３６例发生脑出血；４６例发生脑梗塞。４０例Ⅰ期高血压作对照。全部患者均作２４小时动态血压测定。结果脑出血组与脑梗塞组２４小时及夜间平均收缩压和舒张压均较对照组升高，有显著差异（Ｐ＜０．０５），但脑出血组较脑梗塞组更明显，二者有显著差异（Ｐ＜０．０５）。上午平均舒张压和下午平均收缩压脑出血组高于脑梗塞组，差异显著（Ｐ＜０．０５）。血压下降率在脑出血组与脑梗塞组亦有明显差异（Ｐ＜０．０５）。结论血压的昼夜波动变化特点与发生脑卒中的类型有密切关系。
Objective To investigate the circadian blood pressure changes in patients with hypertensive cerebral hemorrhage and cerebral infarction. Methods Cerebral hemorrhage occurred in 36 cases of 82 hypertensive patients and 46 cases of cerebral infarction. 40 cases of hypertension as a control. All patients were 24 hours ambulatory blood pressure measurement. Results The average systolic and diastolic blood pressure in cerebral hemorrhage group and cerebral infarction group at 24 hours and at night were significantly higher than those in control group (P <0.05), but the cerebral hemorrhage group was more obvious than the cerebral infarction group Significant difference (P <0.05). The mean diastolic pressure in the morning and mean systolic pressure in the afternoon were higher in the cerebral hemorrhage group than in the cerebral infarction group, with significant difference (P <0.05). The rate of decrease of blood pressure was also significantly different between cerebral hemorrhage group and cerebral infarction group (P <0.05). Conclusion The fluctuation of blood pressure is closely related to the type of stroke.
