长期高血压引起大脑血液循环适应性的改变是中风和TIA的最重要的危险因子。抗高血压治疗可以预防中风,但不能预防急性心肌梗死。高血压往往会有头痛症状,偶尔还会发展为急性高血压脑病,二者通过降压治疗均可得到好转,而头痛也有可能是某些降压药物的副作用。高血压亦有可能与脑室周围的白质丧失有关,通过MRI或CT等影像技术可以查清。 The long-term hypertension-induced altered cerebral blood circulation is the most important risk factor for stroke and TIA. Antihypertensive treatment can prevent stroke, but can not prevent acute myocardial infarction. Hypertension often presents with headache symptoms and occasional development of acute hypertensive encephalopathy, both of which can be ameliorated by antihypertensive therapy and headache may also be a side effect of certain antihypertensive drugs. High blood pressure may also be related to the loss of white matter around the ventricle, MRI or CT imaging techniques can be found.
