Sleep and wake episodes during such studies are usually identified by means of sleep diaries but these may be inaccurate in stroke patients. We performed a study to determine whether sleep\u2013wake data obtained using wrist-mounted actimeters would significantly influence the results of routinely performed nocturnal ambulatory blood pressure monitoring when compared with diary-based sleep\u2013wake recording and fixed time-period data.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>Actimetry was performed using a wrist-mounted device during routine ambulatory blood pressure monitoring in subjects who had suffered a transient ischaemic attack or stroke.

Patients were found to have slept for a median of six-hours (one- to eight-hours) by diary and five-hours (zero- to eight-hours) by actimeter data. Diary and actimeter data agreed in 69% of recordings. The mean sleeping systolic blood pressure was lower when calculated by actimeter data than by diary data (119\u00b76 mmHg vs. 123\u00b72 mmHg, P = 0\u00b7049, paired t-test) but there was no significant difference in diastolic blood pressure. The mean nocturnal blood pressure calculated from 11:00 pm to 7:00 am was higher than sleeping blood pressure calculated from diary data, (mean systolic blood pressure: 127\u00b76 mmHg vs. 123\u00b76 mmHg, P = 0\u00b7065; mean diastolic blood pressure 69\u00b70 vs. 64\u00b70, P = 0\u00b7028).<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Calculation of nocturnal and sleeping blood pressure is lower in subjects with stroke and transient ischaemic attack when objective actimeter-derived sleep\/wake data are used.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.1111\/j.1747-4949.2011.00593.x","type":"journal-article","created":{"date-parts":[[2011,4,18]],"date-time":"2011-04-18T02:33:23Z","timestamp":1303094003000},"page":"388-391","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Actimeter-Derived Sleep and Wake Data and Nocturnal Ambulatory Blood Pressure Estimation in Subjects with Stroke and Transient Ischaemic Attack"],"prefix":"10.1177","volume":"6","author":[{"given":"Blaithin Ni","family":"Bhuachalla","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Suzanne","family":"Walsh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Joseph","family":"Harbison","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2011,4,18]]},"reference":[{"key":"bibr1-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1016\/0140-6736(90)90878-9"},{"key":"bibr2-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.313.7050.147"},{"key":"bibr3-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1016\/S0140-6736(10)60308-X"},{"key":"bibr4-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1161\/01.HYP.0000170138.56903.7a"},{"key":"bibr5-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1136\/bmj.320.7242.1128"},{"key":"bibr6-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1161\/01.HYP.0000258215.26755.20"},{"key":"bibr7-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/30.4.519"},{"key":"bibr8-j.1747-4949.2011.00593.x","first-page":"363","volume":"3","author":"Barna I","year":"1998","journal-title":"Blood Press Monit"},{"key":"bibr9-j.1747-4949.2011.00593.x","first-page":"31","volume":"27","author":"Falconer M","year":"2009","journal-title":"Cerebrovasc Dis"},{"key":"bibr10-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.5664\/jcsm.27281"},{"key":"bibr11-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1093\/sleep\/18.8.646"},{"key":"bibr12-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1159\/000165344"},{"key":"bibr13-j.1747-4949.2011.00593.x","first-page":"65","volume":"5","author":"O'Shea JC","year":"2000","journal-title":"Blood Press Monit"},{"key":"bibr14-j.1747-4949.2011.00593.x","doi-asserted-by":"publisher","DOI":"10.1097\/00126097-200102000-00004"}],"container-title":["International Journal of Stroke"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/api.wiley.com\/onlinelibrary\/tdm\/v1\/articles\/10.1111%2Fj.1747-4949.2011.00593.x","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1111\/j.1747-4949.2011.00593.x","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1111\/j.1747-4949.2011.00593.x","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1111\/j.1747-4949.2011.00593.x","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T04:43:30Z","timestamp":1777610610000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1111\/j.1747-4949.2011.00593.x"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011,4,18]]},"references-count":14,"journal-issue":{"issue":"5","published-print":{"date-parts":[[2011,10]]}},"alternative-id":["10.1111\/j.1747-4949.2011.00593.x"],"URL":"https:\/\/doi.org\/10.1111\/j.1747-4949.2011.00593.x","relation":{},"ISSN":["1747-4930","1747-4949"],"issn-type":[{"value":"1747-4930","type":"print"},{"value":"1747-4949","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011,4,18]]}}}
