高血压是一个临床症状,并非病名。约80～90%的高血压是由于高血压病引起的。高血压病是以血压增高为其主要临床表现的一种疾病,由于病因不清称为原发性高血压,有人简称为高血压病。而另外约有10～20%的高血压是由于在肾炎、甲亢、嗜铬细胞瘤等疾病中作为继发症状的一种表现而出现的。高血压症状在这些疾病中可有可无,亦可为暂时或为持久性。为了使后者与前者的概念避免混淆,故又称后者为继发性高血压或症状性高血压。 Hypertension is a clinical symptom, not a disease name. About 80 ~ 90% of hypertension is caused by hypertension. Hypertension is a high blood pressure as its main clinical manifestations of a disease, due to etiology is not known as essential hypertension, some referred to as hypertension. In addition, about 10 to 20% of hypertension is due to nephritis, hyperthyroidism, pheochromocytoma and other diseases as a secondary symptom of a manifestation. Hypertension symptoms are dispensable in these conditions and can be temporary or permanent. In order to avoid confusion between the latter and the former concept, it is also referred to as the latter being secondary to hypertension or symptomatic hypertension.
