The influence of daytime blood pressure (BP) levels and aging on short-term BP variability during sleep in OSAS patients was investigated.<\/jats:p><jats:p>Twenty-nine subjects with newly-diagnosed untreated OSAS were categorised into three groups: normotensive subjects aged &lt;50\u2005yrs (n=10); subjects aged &lt;50\u2005yrs with untreated hypertension (n=8); and normotensive subjects aged &gt;50\u2005yrs (n=11). Beat-by-beat BP was recorded with a Finapres device during polysomnography. The average values\u00b1sd of apnoea-related BP elevations and the values of the frequency distribution of all BP variations during sleep were assessed to estimate short-term BP variability.<\/jats:p><jats:p>Apnoea-related systolic (or diastolic) BP elevations were significantly greater in hypertensives than in normotensives aged &lt;50\u2005yrs (50.3\u00b14.88<jats:italic>versus<\/jats:italic>30.7\u00b12.14\u2005mmHg, p&lt;0.001), as was the sd of systolic (or diastolic) BP variations during sleep (I9.6\u00b12.22<jats:italic>versus<\/jats:italic>11.1\u00b10.73, p&lt;0.001). Short-term BP variability was not significantly increased in normotensive elderly patients.<\/jats:p><jats:p>To conclude, the results suggested that systemic hypertension is associated with a greater exacerbation of short-term variability during sleep in obstructive sleep apnoea syndrome patients.<\/jats:p>","DOI":"10.1183\/09031936.02.00272202","type":"journal-article","created":{"date-parts":[[2002,10,11]],"date-time":"2002-10-11T18:37:23Z","timestamp":1034361443000},"page":"151-157","source":"Crossref","is-referenced-by-count":15,"title":["Exacerbation of sleep-apnoea related nocturnal blood-pressure fluctuations in hypertensive subjects"],"prefix":"10.1183","volume":"20","author":[{"given":"C.","family":"Plan\u00e8s","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Leroy","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"G.","family":"Fayet","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"P.","family":"Aegerter","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Foucher","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"B.","family":"Raffestin","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"81","published-online":{"date-parts":[[2002,7,1]]},"reference":[{"key":"2024101809353607000_20.1.151.1","first-page":"382","volume":"120","year":"1994","journal-title":"Arch Int Med"},{"key":"2024101809353607000_20.1.151.2","doi-asserted-by":"publisher","DOI":"10.1001\/archinte.1997.00440360178019"},{"key":"2024101809353607000_20.1.151.3","doi-asserted-by":"publisher","DOI":"10.1056\/NEJM200005113421901"},{"key":"2024101809353607000_20.1.151.4","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.320.7233.479"},{"key":"2024101809353607000_20.1.151.5","doi-asserted-by":"crossref","first-page":"S529","DOI":"10.1097\/00004872-198812040-00166","volume":"6","year":"1988","journal-title":"J Hypertens"},{"key":"2024101809353607000_20.1.151.6","doi-asserted-by":"publisher","DOI":"10.1161\/01.CIR.98.11.1071"},{"key":"2024101809353607000_20.1.151.7","doi-asserted-by":"crossref","first-page":"1897","DOI":"10.1172\/JCI118235","volume":"96","year":"1995","journal-title":"J Clin Invest"},{"key":"2024101809353607000_20.1.151.8","doi-asserted-by":"publisher","DOI":"10.1161\/01.HYP.31.1.68"},{"key":"2024101809353607000_20.1.151.9","doi-asserted-by":"publisher","DOI":"10.1097\/00004872-198702000-00013"},{"key":"2024101809353607000_20.1.151.10","doi-asserted-by":"publisher","DOI":"10.1097\/00004872-199310000-00019"},{"key":"2024101809353607000_20.1.151.11","first-page":"H1768","volume":"275","year":"1998","journal-title":"Am J Physiol"},{"key":"2024101809353607000_20.1.151.12","doi-asserted-by":"publisher","DOI":"10.1161\/01.HYP.28.6.937"},{"key":"2024101809353607000_20.1.151.13","unstructured":"Rechtschaffen A, Kales A.
