Whether improving obstructive sleep apnoea (OSA) severity improves the HR response to both obstructive and central events remains unknown. Twenty\u2010four children (3\u201319\u2009years at baseline) were included. Children were grouped into improved (decrease in obstructive apnoea\u2010hypopnoea index to \u2264\u200950% of baseline;\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200912; seven treated between studies) and unimproved (\n                    <jats:italic>n<\/jats:italic>\n                    \u2009=\u200912; two treated between studies) 2\u2009years following baseline study. Beat\u2010to\u2010beat HR was averaged 10\u2009s before (pre), during, and the peak after (post) each obstructive and central event during sleep, expressed as percentage change. A total of 1018 obstructive respiratory events were analysed during total sleep; 583 events were analysed at baseline and 435 at follow\u2010up. A total of 330 central events were analysed during total sleep; 164 central events were at baseline and 166 were at follow\u2010up. In the unimproved group, the % change in HR from during the event to post\u2010event was smaller at follow\u2010up for both obstructive (mean 16.8%, 95% CI [17.4%, 20.6%] vs. 22.3% [21.1%, 26.0%] and central events: 15.8% [13.6%, 17.9%] vs. 26.1% [22.4%, 29.9%];\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.05 for both). % change remained unchanged between studies in the improved group. These results suggest that the dampened HR response to respiratory events seen in children with DS worsens over time when OSA does not improve, adding weight to the need for diagnosis and management of OSA in this population.\n                  <\/jats:p>","DOI":"10.1111\/jsr.70053","type":"journal-article","created":{"date-parts":[[2025,3,30]],"date-time":"2025-03-30T11:21:06Z","timestamp":1743333666000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":1,"title":["Improving Obstructive Sleep Apnoea Mitigates Dampened Heart Rate Responses to Respiratory Events in Children With Down Syndrome"],"prefix":"10.1111","volume":"34","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-1158-493X","authenticated-orcid":false,"given":"Lisa M.","family":"Walter","sequence":"first","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Marisha","family":"Shetty","sequence":"additional","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ahmad","family":"Bassam","sequence":"additional","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Margot J.","family":"Davey","sequence":"additional","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"},{"name":"Melbourne Children's Sleep Centre Monash Children's Hospital  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4944-7754","authenticated-orcid":false,"given":"Gillian M.","family":"Nixon","sequence":"additional","affiliation":[{"name":"Department of Paediatrics Monash University  Melbourne Australia"},{"name":"Melbourne Children's Sleep Centre Monash Children's Hospital  Melbourne Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3575-0461","authenticated-orcid":false,"given":"Rosemary S.
