Increasing evidence suggests that aldosterone and endothelins promote sympathetic overstimulation of failing hearts. Salt-sensitive Dahl rats (DS) fed a high-salt diet developed arterial hypertension and diastolic heart failure as well as elevated plasma levels of endothelin-1 and NE. Cardiac NE reuptake and NET-binding sites, as assessed by clearance of bolus-injected [3H]NE in isolated perfused rat hearts and [3H]mazindol binding, were reduced. Treatment of DS with the mineralocorticoid receptor antagonist spironolactone preserved the plasma levels of endothelin-1 and NE, cardiac NE reuptake, and myocardial NET density. Moreover, the ventricular function and survival of spironolactone-treated DS were significantly improved compared with untreated DS. The \u03b11-inhibitor prazosin decreased blood pressure in DS similar to spironolactone treatment, but did not normalize the plasma levels of endothelin-1 and NE, NE reuptake, or ventricular function. In a heart failure-independent model, Wistar rats that were infused with aldosterone and fed a high-salt diet developed impaired cardiac NE reuptake. Treatment of these rats with the endothelin A receptor antagonist darusentan attenuated the impairment of NE reuptake. In conclusion, spironolactone preserves NET-dependent cardiac NE reuptake in salt-dependent heart failure. Evidence is provided that aldosterone inhibits NET function through an interaction with the endothelin system. Selective antagonism of the mineralocorticoid and\/or the endothelin A receptor might represent therapeutic principles to prevent cardiac sympathetic overactivity in salt-dependent heart failure.<\/jats:p>","DOI":"10.1210\/en.2005-1167","type":"journal-article","created":{"date-parts":[[2006,1,27]],"date-time":"2006-01-27T01:32:55Z","timestamp":1138325575000},"page":"2526-2534","source":"Crossref","is-referenced-by-count":31,"title":["Spironolactone Preserves Cardiac Norepinephrine Reuptake in Salt-Sensitive Dahl Rats"],"prefix":"10.1210","volume":"147","author":[{"given":"Sebastian J.","family":"Buss","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Johannes","family":"Backs","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michael M.","family":"Kreusser","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan E.","family":"Hardt","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Christiane","family":"Maser-Gluth","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hugo A.","family":"Katus","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Markus","family":"Haass","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"80","reference":[{"key":"2020071612481453300_R1","doi-asserted-by":"crossref","first-page":"1259","DOI":"10.1016\/S0002-9149(99)80353-1","article-title":"Effects of adding spironolactone to an angiotensin-converting enzyme inhibitor in chronic congestive heart failure secondary to coronary artery disease.","volume":"76","author":"Barr","year":"1995","journal-title":"Am J Cardiol"},{"key":"2020071612481453300_R2","doi-asserted-by":"crossref","first-page":"1309","DOI":"10.1056\/NEJMoa030207","article-title":"Eplerenone, a selective aldosterone blocker, in patients with left ventricular dysfunction after myocardial infarction.","volume":"348","author":"Pitt","year":"2003","journal-title":"N Engl J Med"},{"key":"2020071612481453300_R3","doi-asserted-by":"crossref","first-page":"709","DOI":"10.1056\/NEJM199909023411001","article-title":"The effect of spironolactone on morbidity and mortality in patients with severe heart failure.
