原发性高血压的病因大致为二类。第一类由血管收缩引起,第二类则由血容量增加所致。前者大多为高肾素性以及一部分正常肾素性的原发性高血压。第二类高血压常与钠离子及盐皮质类固醇的活性有关。在临床上,低肾素性原发性高血压与假性原发性醛固酮增多症(Pseudoprimary aldos-teronism)有时不易鉴别,故有人提出假性原醛是否是低肾素性原发性高血压的一种表现。原发性醛固酮增多症是由于肾上腺皮质的单个腺瘤所致,切除腺瘤常可纠正代谢异常并 The causes of essential hypertension are roughly two categories. The first category is caused by vasoconstriction, and the second category is caused by an increase in blood volume. The former mostly high renin as well as part of the normal renin of essential hypertension. The second category of hypertension and sodium ion and salt corticosteroid activity. Clinically, low-renin essential hypertension and pseudo-primary aldosteronism (Pseudoprimary aldos-teronism) is sometimes not easy to identify, it was put forward pseudo-original aldehyde whether low-renin essential hypertension is a Performance. Primary aldosteronism is due to a single adenoma of the adrenal cortex, removal of adenomas often corrects metabolic abnormalities and
