脑血管意外(CVA)患者常伴高血压,其降压治疗因病型与病情不同而异。慢性期的降压治疗可预防CVA复发及降低死亡率。急性CVA时的降压处理也因病型不同而异。此外,CVA时的血压变化除对脑循环有明显影响外,在降压治疗时对心、肺、肾等重要脏器的影响亦不容忽视。在决定降压时应考虑以下病理生理。 1.不论何种CVA或以往有无高血压,在CVA发病后一般均有血压增高。在严重、广泛脑损害时血压显著上升,系因脑水肿或脑脊液有血引起颅内压增高所致血压反应性增高 Patients with cerebrovascular accident (CVA) often have high blood pressure, and its antihypertensive treatment varies according to the type and condition of the patient. Antihypertensive treatment of chronic phase can prevent recurrence of CVA and reduce mortality. Antihypertensive treatment of acute CVA also varies due to different types of disease. In addition, CVA blood pressure changes in addition to a significant effect on cerebral circulation, the antihypertensive treatment of heart, lung, kidney and other important organs can not be ignored. The following pathophysiology should be considered when deciding to step down. 1. No matter what kind of CVA or in the past with or without high blood pressure, blood pressure generally increases after the onset of CVA. In severe, extensive brain damage when blood pressure increased significantly due to cerebral edema or cerebrospinal fluid blood caused by increased intracranial pressure due to increased blood pressure response
