The aim of the study was to prospectively analyze the risk factors attributed to syncope recurrence. &lt;b&gt;&lt;i&gt;Materials and Methods:&lt;\/i&gt;&lt;\/b&gt; Between 2009 and 2010, 289 patients with all cause of syncope visited our institution. Syncope recurrences were followed for 1 year by telephone interview every 3 months. &lt;b&gt;&lt;i&gt;Results:&lt;\/i&gt;&lt;\/b&gt; We diagnosed 181 (63%) patients with neurally mediated syncope (NMS), 39 (13%) with orthostatic hypotension, 34 (12%) with cardiac syncope, and 35 (12%) with unexplained syncope. During the 1-year follow-up period, 19 (6.6%) patients suffered recurrent syncope. Kaplan-Meier curves showed that recurrent syncope was observed more often in patients with unexplained syncope compared with those with NMS (p &lt; 0.01), and also observed more often in patients with six previous syncopal episodes compared to those with fewer episodes (p = 0.02). Cox regression analysis showed that the recurrence of syncope was significantly associated with more than six previous syncopal episodes (HR 5.38, 95% CI 1.17-24.71, p = 0.03) and that there was a tendency for association between recurrence of syncope and unexplained syncope (HR 6.13, 95% CI 0.96-39.1, p = 0.05). &lt;b&gt;&lt;i&gt;Conclusions:&lt;\/i&gt;&lt;\/b&gt; Patients with previous frequent syncopal episodes or unexplained syncope had higher rates of syncope recurrence during the follow up period.<\/jats:p>","DOI":"10.1159\/000366267","type":"journal-article","created":{"date-parts":[[2017,4,18]],"date-time":"2017-04-18T21:52:56Z","timestamp":1492552376000},"page":"233-239","source":"Crossref","is-referenced-by-count":0,"title":["Clinical Factors Affecting Symptom Recurrence in Patients with Syncope"],"prefix":"10.1159","volume":"129","author":[{"given":"Sung Ho","family":"Lee","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Bum Soo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Seung-Jung","family":"Park","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Young Keun","family":"On","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"June","family":"Huh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"June Soo","family":"Kim","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2014,11,11]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/S0002-9343(01)00797-5"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1097\/00005792-199005000-00004"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/0002-9343(87)90901-6"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1053\/euhj.2001.2739"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/j.ahj.2003.11.022"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1016\/0895-4356(91)90005-T"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1053\/eupc.2001.0182"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2008.01352.x"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1111\/j.1540-8167.2010.01848.x"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1007\/s10286-011-0125-7"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1093\/eurheartj\/ehp298"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.93.5.973"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.99.3.406"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/j.ehj.2004.05.013"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016\/j.eupc.2004.09.003"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016\/j.eupc.2005.02.116"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016\/j.ijcard.2013.04.179"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.3349\/ymj.2013.54.3.590"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1016\/j.hrthm.2011.01.039"},{"key":"ref20","doi-asserted-by":"publisher","DOI":"10.1016\/j.jacc.2006.06.059"}],"container-title":["Cardiology"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/366267","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/366267","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/366267","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T17:36:49Z","timestamp":1745429809000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000366267"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2014]]},"references-count":20,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2014,11,1]]},"published-print":{"date-parts":[[2014,12,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000366267","archive":["Portico"],"relation":{},"ISSN":["0008-6312","1421-9751"],"issn-type":[{"type":"print","value":"0008-6312"},{"type":"electronic","value":"1421-9751"}],"subject":[],"published":{"date-parts":[[2014]]}}}
