症状性高血压又称继发性高血压,此种高血压是某些疾病的一部分表现,其中有些原发病治愈之后,高血压就消失了。高血压病人中约有10～20%为继发性高血压。其病因常见的有:1.泌尿系统疾病:(1)肾实质性疾病:急性及慢性肾小球肾炎、肾盂肾炎、多囊肾、胶原疾患所致肾损害。由于血容量增加,心排血量增加而使血压升高。(2)肾动脉病变:肾动脉狭窄、硬化、血栓形成等导致的肾缺血引起的肾素分泌增加。 Symptomatic Hypertension, also known as secondary hypertension, is a symptom of some diseases, some of which disappear after the primary disease is cured. About 10 to 20% of hypertensive patients are secondary to hypertension. Common causes of the disease are: 1. Urinary system diseases: (1) renal parenchymal disease: acute and chronic glomerulonephritis, pyelonephritis, polycystic kidney disease, kidney damage caused by collagen disease. Due to increased blood volume, increased cardiac output increased blood pressure. (2) renal artery lesions: Renal artery stenosis, sclerosis, thrombosis caused by renal ischemia caused by increased renin secretion.
