However, obtaining reliable and reproducible BP remains a challenge. This study, therefore, aimed to evaluate a novel cuffless wristband, based on photoplethysmography (PPG), for continuous BP monitoring.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods and results<\/jats:title>\n                  <jats:p>Predictions by a PPG-guided algorithm were compared to arterial BP measurements (in the sub-clavian artery), obtained during cardiac catheterization. Eligible patients were included and screened based on AAMI\/European Society of Hypertension (ESH)\/ISO Universal Standard requirements. The machine learning-based BP algorithm required three cuff-based initialization measurements in combination with \u223c100 features (signal-derived and patient demographic-based). Ninety-seven patients and 420 samples were included. Mean age, weight, and height were 67.1 years (SD 11.1), 83.4\u2005kg (SD 16.1), and 174\u2005cm (SD 10), respectively. Systolic BP was \u2264100\u2005mmHg in 48 samples (11%) and \u2265160\u2005mmHg in 106 samples (25%). Diastolic BP was \u226470\u2005mmHg in 222 samples (53%) and \u226585\u2005mmHg in 99 samples (24%). The algorithm showed mean errors of \u00b13.7\u2005mmHg (SD 4.4\u2005mmHg) and \u00b12.5\u2005mmHg (SD 3.7\u2005mmHg) for systolic and diastolic BP, respectively. Similar results were observed across all genders and skin colours (Fitzpatrick I-VI).<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Conclusion<\/jats:title>\n                  <jats:p>This study provides initial evidence for the accuracy of a PPG-based BP algorithm in combination with a cuffless wristband across a range of BP distributions. This research complies with the AAMI\/ESH\/ISO Universal Standard, however, further research is required to evaluate the algorithms performance in light of the remaining European Society of Hypertension recommendations.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Clinical trial registration<\/jats:title>\n                  <jats:p>www.clinicaltrials.gov, NCT05566886.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1093\/ehjdh\/ztae006","type":"journal-article","created":{"date-parts":[[2024,2,8]],"date-time":"2024-02-08T20:35:52Z","timestamp":1707424552000},"page":"335-343","source":"Crossref","is-referenced-by-count":24,"title":["Evaluation of a novel cuffless photoplethysmography-based wristband for measuring blood pressure according to the regulatory standards"],"prefix":"10.1093","volume":"5","author":[{"given":"Mariska","family":"van Vliet","sequence":"first","affiliation":[{"name":"Department of Cardiology, Reinier de Graaf Hospital , Reinier de Graafweg 5, 2625 AD Delft , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Stefan H J","family":"Monnink","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Reinier de Graaf Hospital , Reinier de Graafweg 5, 2625 AD Delft , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mathijs J","family":"Kuiper","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Reinier de Graaf Hospital , Reinier de Graafweg 5, 2625 AD Delft , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jan C","family":"Constandse","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Reinier de Graaf Hospital , Reinier de Graafweg 5, 2625 AD Delft , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dieke","family":"Hoftijzer","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Reinier de Graaf Hospital , Reinier de Graafweg 5, 2625 AD Delft , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4032-7863","authenticated-orcid":false,"given":"Eelko","family":"Ronner","sequence":"additional","affiliation":[{"name":"Department of Cardiology, Reinier de Graaf Hospital , Reinier de Graafweg 5, 2625 AD Delft , The Netherlands"},{"name":"Corsano Health B.V. , Wilhelmina van Pruisenweg 35, 2595 AN The Hague , The Netherlands"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"286","published-online":{"date-parts":[[2024,2,8]]},"reference":[{"key":"2024052015251373900_ztae006-B1","doi-asserted-by":"crossref","first-page":"199","DOI":"10.1186\/cc1489","article-title":"Clinical review: complications and risk factors of peripheral arterial catheters used for haemodynamic monitoring in anaesthesia and intensive care medicine","volume":"6","author":"Scheer","year":"2002","journal-title":"Critical Care"},{"key":"2024052015251373900_ztae006-B2","doi-asserted-by":"crossref","first-page":"35","DOI":"10.1161\/HYP.0000000000000087","article-title":"Measurement of blood pressure in humans: a scientific statement from the American heart association","volume":"73","author":"Muntner","year":"2019","journal-title":"Hypertension"},{"key":"2024052015251373900_ztae006-B3","doi-asserted-by":"crossref","first-page":"162","DOI":"10.1038\/hr.2010.223","article-title":"Blood pressure variability: a confounder and a cardiovascular risk factor","volume":"34","author":"Papadogiannis","year":"2010","journal-title":"Hypertens Res"},{"key":"2024052015251373900_ztae006-B4","doi-asserted-by":"crossref","first-page":"2037","DOI":"10.1097\/HJH.0000000000003228","article-title":"Comparison between cuff-based and invasive systolic blood pressure amplification","volume":"40","author":"Bui","year":"2022","journal-title":"J.
