对９４例有高血压病史的脑卒中死亡病例（脑出血４６例，脑梗塞４８例）病前、起病时及起病后不同时间血压变化的平均数值进行了比较研究。结果：脑出血与脑梗塞组之间病前血压的比较无显著差异（Ｐ＞０．０５），起病时与起病后血压的比较有显著意义（Ｐ＜０．０１，Ｐ＜０．０５）。脑出血患者发病后在原高血压的基础上血压仍显著升高（Ｐ＜０．０１），而脑梗塞患者在病后较病前的血压明显降低（Ｐ＜０．０１，Ｐ＜０．０５）。提示脑卒中与血压的变化有密切关系，脑卒中时血压过高可以加重病情及增加致死率，然而，血压降得过低，又能增加脑缺血的危险。
94 patients with a history of hypertension stroke death cases (46 cases of cerebral hemorrhage, 48 cases of cerebral infarction) before and during the onset and onset of different time after the mean changes in blood pressure were compared. Results: There was no significant difference in the prehypertensive blood pressure between cerebral hemorrhage and cerebral infarction groups (P> 0.05). There was a significant difference between the onset and post - onset blood pressure (P <0.01, P <0. 05). The incidence of cerebral hemorrhage in patients with hypertension on the basis of the original blood pressure was significantly higher (P <0.01), while patients with cerebral infarction in the disease after the disease than before the blood pressure was significantly lower (P <0.01, P <0.05 ). Tip stroke and blood pressure changes are closely related to high blood pressure during stroke can aggravate the condition and increase mortality, however, low blood pressure, but also increase the risk of cerebral ischemia.
