The captopril test has been suggested as a sensitive and specific noninvasive tool for the diagnosis of renovascular hypertension. We applied the test to 72 consecutive hypertensive patients in whom renal artery stenosis was suspected. The test was positive in seven cases (9.7%), of whom four were true positive and three false positive. The captopril test has value in screening for renovascular hypertension, but its limitations should be recognized. False positive results are not uncommon and false negative results have been reported under certain circumstances. Nevertheless, when properly applied to appropriate patients, the test can enhance the diagnosis of renal artery stenosis.
卡托普利试验已被认为是诊断肾血管性高血压的一种敏感且特异的非侵入性工具。我们对72例连续的疑似肾动脉狭窄的高血压患者进行了该试验。试验结果阳性的有7例（9.7%），其中4例为真阳性，3例为假阳性。卡托普利试验在筛查肾血管性高血压方面有价值，但应认识到其局限性。假阳性结果并不罕见，在某些情况下也有假阴性结果的报道。然而，当正确应用于合适的患者时，该试验可提高肾动脉狭窄的诊断率。
