We obtained simultaneous venous blood samples from the left renal vein and a peripheral vein and from the radial artery in 28 patients with primary aldosteronism and 10 patients with essential hypertension. Renal extraction of atrial natriuretic peptide was significantly (<jats:italic>P<\/jats:italic>&lt;.001) reduced (40\u00b12%) in primary aldosteronism compared with essential hypertensive patients (62\u00b13%). Peripheral forearm extraction was also reduced (<jats:italic>P<\/jats:italic>&lt;.01) in primary aldosteronism compared with essential hypertensive patients (24\u00b13% versus 38\u00b14%). These findings are consistent with widespread downregulation of atrial natriuretic peptide receptors in primary aldosteronism. Consistent with reports that marked reduction in glomerular filtration rate is required before the renal extraction of atrial natriuretic peptide is reduced, no significant relationship between renal extraction of atrial natriuretic peptide and plasma creatinine was seen in primary aldosteronism or essential hypertension. Although the major regulators of atrial natriuretic peptide secretion in primary aldosteronism are presumably alterations in arterial blood pressure and plasma volume, reduced renal and peripheral extraction of atrial natriuretic peptide in primary aldosteronism may also contribute significantly to the elevated circulating levels observed.<\/jats:p>","DOI":"10.1161\/01.hyp.26.4.624","type":"journal-article","created":{"date-parts":[[2012,6,12]],"date-time":"2012-06-12T00:24:03Z","timestamp":1339460643000},"page":"624-627","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":2,"title":["Reduced Renal Extraction of Atrial Natriuretic Peptide in Primary Aldosteronism"],"prefix":"10.1161","volume":"26","author":[{"given":"Terry J.","family":"Tunny","sequence":"first","affiliation":[{"name":"From the Hypertension Unit, Greenslopes Hospital, Brisbane, Queensland, Australia."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard D.","family":"Gordon","sequence":"additional","affiliation":[{"name":"From the Hypertension Unit, Greenslopes Hospital, Brisbane, Queensland, Australia."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shelley A.","family":"Klemm","sequence":"additional","affiliation":[{"name":"From the Hypertension Unit, Greenslopes Hospital, Brisbane, Queensland, Australia."}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Michael","family":"Stowasser","sequence":"additional","affiliation":[{"name":"From the Hypertension Unit, Greenslopes Hospital, Brisbane, Queensland, Australia."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"276","reference":[{"key":"e_1_3_2_1_2","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1981.00340130033011"},{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1111\/j.1440-1681.1985.tb02641.x"},{"key":"e_1_3_2_3_2","unstructured":"Gordon RD Stowasser M Klemm SA Tunny TJ.
