Methods: Evaluation of motor functions and total functional capacity was performed in 30 HD mutation carriers or patients at the beginning and in 22 subjects after 8\u201310 years. Continuous arterial blood pressure, heart rate (HR), and ECG at rest were measured, and HR variability analysis was performed in four different ways. A group of matched controls was also evaluated. Results: Eighteen subjects were assorted in 3 groups: 6 HD mutation carriers without motor symptoms (PHD) who remained so (PHD-PHD); 6 early symptomatic patients (EHD) who remained so (EHD-EHD); and 6 early symptomatic patients who deteriorated to a late symptomatic (LHD) (EHD-LHD). At the beginning, sympathetic tonic activity in PHD was elevated, according to mean arterial pressure (99 \u00b1 10.6 mm Hg) higher than in controls (85 \u00b1 8.7 mm Hg) and EHD (82 \u00b1 9.9 mm Hg) (Dunnett\u2019s test, p &lt; 0.05) and higher HR (78 \u00b1 16 beats\/min) than after 8\u201310 years (64 \u00b1 11.3 beats\/min) (paired t test, p &lt; 0.05). There was also a decreased phasic sympathetic activity in EHD patients compared controls at the beginning (219 \u00b1 106 vs. 664 \u00b1 466 s2\/Hz) and after 8\u201310 years (182 \u00b1 136 vs. 1,012 \u00b1 1,369 s2\/Hz) (Dunnett\u2019s test, p &lt; 0.05). In patients who deteriorated from EHD to LHD, there was a drop in phasic parasympathetic activity from 887 \u00b1 433 to 230 \u00b1 235 s2\/Hz (paired t test, p &lt; 0.05). Conclusions: Our long-term observational study provides important information on the timeline of ANS activity in HD progress. There was a temporary increase in cardiac and vascular sympathetic activity in PHD subjects. The normalization of HR in PHD subjects might indicate the approach of an outbreak of clinical disease phase. <\/jats:p>","DOI":"10.1159\/000525415","type":"journal-article","created":{"date-parts":[[2022,6,29]],"date-time":"2022-06-29T21:00:31Z","timestamp":1656536431000},"page":"1-6","source":"Crossref","is-referenced-by-count":6,"title":["Heart Rate Variability in Huntington Disease: A Long-Term Longitudinal Study"],"prefix":"10.1159","volume":"22","author":[{"given":"Jan","family":"Kobal","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ksenija","family":"Cankar","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0533-9911","authenticated-orcid":false,"given":"Ziva","family":"Melik","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2022,6,29]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016\/s1474-4422(14)70238-8"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1136\/jnnp.2010.208264"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016\/j.expneurol.2011.06.011"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-014-7319-6"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016\/B978-0-12-801893-4.00006-7"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0404.2009.01251.x"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.3389\/fneur.2019.00545"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1007\/s00415-011-6279-3"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1038\/nrneurol.2014.24"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1109\/10.678605"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1152\/ajpheart.00405.2000"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1113\/expphysiol.2010.056259"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1186\/1751-0759-2-12"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1016\/s0361-9230(01)00648-7"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1212\/01.wnl.0000174432.87383.87"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1093\/brain\/awn025"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1111\/j.1468-1331.2008.02173.x"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1186\/1471-2458-11-601"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.3389\/fphys.2018.00559"}],"container-title":["Neurodegenerative Diseases"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/ndd\/article\/22\/1\/1\/825123\/Heart-Rate-Variability-in-Huntington-Disease-A","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/karger.com\/ndd\/article\/22\/1\/1\/825123\/Heart-Rate-Variability-in-Huntington-Disease-A","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T15:04:44Z","timestamp":1745420684000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000525415"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2022]]},"references-count":19,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2022,11,16]]},"published-print":{"date-parts":[[2022,11,29]]}},"URL":"https:\/\/doi.org\/10.1159\/000525415","archive":["Portico"],"relation":{},"ISSN":["1660-2854","1660-2862"],"issn-type":[{"value":"1660-2854","type":"print"},{"value":"1660-2862","type":"electronic"}],"subject":[],"published":{"date-parts":[[2022]]}}}
