In this prospective study of 88 consecutive patients referred to a university clinic for resistant hypertension, we determined the 24-hour urinary aldosterone excretion during high dietary salt ingestion, baseline plasma renin activity, and plasma aldosterone in all subjects. Primary hyperaldosteronism was confirmed if plasma renin activity was &lt;1.0 ng\/mL per hour and urinary aldosterone was &gt;12 \u03bcg\/24-hour during high urinary sodium excretion (&gt;200 mEq\/24-hour). Eighteen subjects (20%) were confirmed to have primary hyperaldosteronism. The prevalence of hyperaldosteronism was similar in black and white subjects. Of the 14 subjects with confirmed hyperaldosteronism who have been treated with spironolactone, all have manifested a significant reduction in blood pressure. In this population, an elevated plasma aldosterone\/plasma renin activity ratio (&gt;20) had a sensitivity of 89% and a specificity of 71% with a corresponding positive predictive value of 44% and a negative predictive value of 96%. These data provide strong evidence that hyperaldosteronism is a common cause of resistant hypertension in black and white subjects. The accuracy of these results is strengthened by having done suppression testing of all evaluated subjects.<\/jats:p>","DOI":"10.1161\/01.hyp.0000040261.30455.b6","type":"journal-article","created":{"date-parts":[[2002,12,5]],"date-time":"2002-12-05T16:43:15Z","timestamp":1039106595000},"page":"892-896","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":634,"title":["Hyperaldosteronism Among Black and White Subjects With Resistant Hypertension"],"prefix":"10.1161","volume":"40","author":[{"given":"David A.","family":"Calhoun","sequence":"first","affiliation":[{"name":"From the Vascular Biology and Hypertension Program, University of Alabama at Birmingham (M.K.N., M.A.Z.), and the Veterans Affairs Medical Center (D.A.C.), Birmingham, Ala; St. Joseph Mercy Hospital (R.B.T.), Ypsilanti, Mich; and the Hypertension Department, Favaloro Foundation (P.W.), Buenos Aires, Argentina."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mari K.","family":"Nishizaka","sequence":"additional","affiliation":[{"name":"From the Vascular Biology and Hypertension Program, University of Alabama at Birmingham (M.K.N., M.A.Z.), and the Veterans Affairs Medical Center (D.A.C.), Birmingham, Ala; St. Joseph Mercy Hospital (R.B.T.), Ypsilanti, Mich; and the Hypertension Department, Favaloro Foundation (P.W.), Buenos Aires, Argentina."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mohammad A.","family":"Zaman","sequence":"additional","affiliation":[{"name":"From the Vascular Biology and Hypertension Program, University of Alabama at Birmingham (M.K.N., M.A.Z.), and the Veterans Affairs Medical Center (D.A.C.), Birmingham, Ala; St. Joseph Mercy Hospital (R.B.T.), Ypsilanti, Mich; and the Hypertension Department, Favaloro Foundation (P.W.), Buenos Aires, Argentina."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Roopal B.","family":"Thakkar","sequence":"additional","affiliation":[{"name":"From the Vascular Biology and Hypertension Program, University of Alabama at Birmingham (M.K.N., M.A.Z.), and the Veterans Affairs Medical Center (D.A.C.), Birmingham, Ala; St. Joseph Mercy Hospital (R.B.T.), Ypsilanti, Mich; and the Hypertension Department, Favaloro Foundation (P.W.), Buenos Aires, Argentina."}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paula","family":"Weissmann","sequence":"additional","affiliation":[{"name":"From the Vascular Biology and Hypertension Program, University of Alabama at Birmingham (M.K.N., M.A.Z.), and the Veterans Affairs Medical Center (D.A.C.), Birmingham, Ala; St. Joseph Mercy Hospital (R.B.T.), Ypsilanti, Mich; and the Hypertension Department, Favaloro Foundation (P.W.), Buenos Aires, Argentina."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","reference":[{"key":"e_1_3_2_1_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1681.1994.tb02519.x"},{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1016\/S0272-6386(01)80117-7"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1681.1993.tb01687.x"},{"key":"e_1_3_2_4_2","first-page":"1863","volume":"85","year":"2000","unstructured":"Fardella CE, Mosso L, G\u00f3mez-S\u00e1nchez C, Cort\u00e9s P, Pinto M, Huete A, Oestreicher E, Foradori A, Montero J.
