原发性高血压患者中20%～40%血浆肾素活性呈低水平,其原因未明。曾提到这类患者有醛固酮活性偏高,细胞外液潴留,肾上腺有形态学改变,以及这种类型高血压对肾上腺素抑制剂、醛固酮拮抗剂和噻嗪类利尿剂敏感等特征。为证实低肾素原发性高血压患者是否盐皮质激素过高,许多研究者曾测定血液或尿 20% to 40% of patients with essential hypertension plasma renin activity was low, the reason is not yet clear. Mention of such patients have aldosterone activity, extracellular fluid retention, adrenal morphological changes, and this type of hypertension on adrenergic inhibitors, aldosterone antagonists and thiazide diuretics and other sensitive features. To confirm whether mineralocorticoid is too high in patients with low renin hypertension, many researchers have measured blood or urine
