肾血管性高血压尚缺乏一种假阴性率或假阳性率低的简单的筛选试验。血浆肾素活性测定及肾素测定图曾受到重视,约1/2的肾动脉狭窄病人的绝对值及相对值都有所增加。但由于约15％的原发性高血压病人的血浆肾素值也有所升高,且无定形的测定方法,因而在临床应用上受到限制。以往的研究指出Sara-lasin或SQ_(20881)(teprotide)都有使血压立即下降的作用。作者应用此类阻滞剂在47例肾血管性高血压及100例正常肾素型或高肾素型原发性高血压病人
Renal vascular hypertension still lacks a simple screening test with a false negative rate or a low false positive rate. Plasma renin activity and renin measurements have been taken seriously, with an increase in the absolute and relative values of approximately one-half of patients with renal artery stenosis. However, due to the fact that about 15% of patients with essential hypertension also have elevated plasma renin concentrations and no amorphous assay, their clinical application is limited. Previous studies indicated that Sara-lasin or SQ_ (20881) (teprotide) had the effect of lowering blood pressure immediately. The application of such blockers in 47 cases of renovascular hypertension and 100 cases of normal renin or renin hypertensive patients
