To assess whether changes in N-terminal pro-brain natriuretic peptide levels after mitral, aortic, and double-valve replacement reflect changes in heart failure symptoms, a prospective observational nonrandomized study was undertaken in 24 consecutive patients (mean age, 55.3\u2009\u00b1\u200916.2 years; 58% male) undergoing mitral and\/or aortic valve replacement. Mitral valve replacement was carried out in 12 patients, aortic valve replacement in 8, and combined mitral and aortic valve replacement in 4. N-terminal pro-brain natriuretic peptide measurements, echocardiography, and functional class assessment were performed before and 6 months after surgery. A decrease in N-terminal pro-brain natriuretic peptide at 6 months postoperatively was significantly associated with decreased left atrial dimension, left ventricular end-diastolic and end-systolic dimensions, increased ejection fraction, and improvement in functional class. Thus we can hypothesize that measurement of N-terminal pro-brain natriuretic peptide might allow early detection of any clinical deterioration as well as assessment of the long-term outcome in valve replacement patients.<\/jats:p>","DOI":"10.1177\/0218492311424779","type":"journal-article","created":{"date-parts":[[2013,5,6]],"date-time":"2013-05-06T09:37:22Z","timestamp":1367833042000},"page":"399-402","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":1,"title":["NT-pro-brain natriuretic peptide levels after valve replacement"],"prefix":"10.1177","volume":"19","author":[{"given":"Abdelfatah A","family":"Elasfar","sequence":"first","affiliation":[{"name":"Adult Cardiology Department, Prince Salman Heart Center, King Fahad Medical City, Riyadh, Saudi Arabia."}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2011,12,1]]},"reference":[{"key":"bibr1-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejheart.2003.12.015"},{"key":"bibr2-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.87.2.464"},{"key":"bibr3-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.90.1.195"},{"key":"bibr4-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(03)00787-3"},{"key":"bibr5-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1016\/j.ehj.2003.07.005"},{"key":"bibr6-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.0000144310.04433.BE"},{"key":"bibr7-0218492311424779","doi-asserted-by":"crossref","first-page":"159","DOI":"10.1007\/s10554-006-9138-z","volume":"23","author":"Poldermans D","year":"2007","journal-title":"Int J Cardiovasc Imaging"},{"key":"bibr8-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1016\/j.amjcard.2004.01.008"},{"key":"bibr9-0218492311424779","first-page":"608","volume":"6","author":"Brookes CI","year":"1997","journal-title":"J Heart Valve Dis"},{"key":"bibr10-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1016\/S0735-1097(03)00486-8"},{"key":"bibr11-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1309\/PDJ2RMM80FVRDH7W"},{"key":"bibr12-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1007\/s10554-006-9138-z"},{"key":"bibr13-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejheart.2005.08.004"},{"key":"bibr14-0218492311424779","doi-asserted-by":"publisher","DOI":"10.1007\/s00392-010-0118-x"}],"container-title":["Asian Cardiovascular and Thoracic Annals"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0218492311424779","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/0218492311424779","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/0218492311424779","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,28]],"date-time":"2026-04-28T15:15:25Z","timestamp":1777389325000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/0218492311424779"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,12]]},"references-count":14,"journal-issue":{"issue":"6","published-print":{"date-parts":[[2011,12]]}},"alternative-id":["10.1177\/0218492311424779"],"URL":"https:\/\/doi.org\/10.1177\/0218492311424779","relation":{},"ISSN":["0218-4923","1816-5370"],"issn-type":[{"value":"0218-4923","type":"print"},{"value":"1816-5370","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,12]]}}}
