摘要：

The usefulness of the captopril test as a simultaneous screening method for primary aldosteronism (PA) and renovascular hypertension (RVH) was evaluated in 111 patients with essential hypertension, and in 79 patients with secondary hypertension, which included 16 patients with PA and 18 with RVH. Plasma renin activity (PRA, ng/mL/h) and plasma aldosterone concentration (PAC, ng/dL) were determined before and 90 min after administration of 50 mg of captopril in the supine position on a normal NaCl diet. A cutoff point or a discriminant function in the screening was determined by discriminant analysis. A quadratic discriminant function of PRA and PAC after the captopril test identified patients with PA with a false negative rate of 6.3% (1/16), and a false positive rate of 0.6% (1/174) which was significantly lower than that of 3.4% at the basal state (P < .05). In the screening for RVH, the criterion of a postcaptopril PRA of greater than 10.6 ng/mL/h had a false negative rate of 5.6% (1/18) and a false positive rate of 15.1% (26/172). This false positive rate was also significantly lower than that using a criterion for precaptopril PRA of 2.21 ng/mL/h (P < .05). Accordingly, the captopril test was a useful method in the simultaneous screening for PA and RVH, and it may be particularly applicable in specialized hypertension clinics.
