发病机制以血浆肾素和血管紧张素过多,小动脉收缩为主要因素的高血压病称为血管收缩性高血压。如恶性高血压、高肾素型原发性高血压、肾血管型高血压均属于收缩性高血压。以水钠过多为主要发病机制的高血压为容量性高血压。此型高血压血浆肾素活性降低,小动脉相对扩张、血浆及细胞外液容量增高,双侧肾病性高血压等属于此种类型。 Pathogenesis To plasma renin and angiotensin, arteriolar contraction as the main factor of hypertension is called vasoconstrictive hypertension. Such as malignant hypertension, high renin-type hypertension, renovascular hypertension are contractile hypertension. To sodium and water as the main pathogenesis of hypertension for the capacity of hypertension. This type of hypertension with reduced plasma renin activity, relative expansion of arterioles, increased plasma and extracellular fluid volume, bilateral renal hypertension and so on are of this type.
