While pulmonary artery catheterisation remains the gold standard, its invasive nature necessitates reliable noninvasive alternatives. However, the literature on echocardiographic SV accuracy is inconsistent. This study evaluated commonly used echocardiographic techniques\u2014Doppler-derived and Simpson\u2019s method\u2014against invasive thermodilution in 39 patients. SV by Doppler showed strong correlation (\n                    <jats:italic toggle=\"yes\">r<\/jats:italic>\n                    \u2009=\u20090.91,\n                    <jats:italic toggle=\"yes\">p<\/jats:italic>\n                    \u2009&lt;\u20090.0001) and minimal bias, whereas the Simpson\u2019s method exhibited weaker correlation and more significant underestimation. These findings suggest Doppler echocardiography as the more accurate noninvasive tool for SV estimation, addressing prior discrepancies and enhancing haemodynamic management in critical care.\n                  <\/jats:p>","DOI":"10.1177\/17511437251338609","type":"journal-article","created":{"date-parts":[[2025,5,8]],"date-time":"2025-05-08T14:03:03Z","timestamp":1746712983000},"page":"532-534","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Doppler echocardiography: The noninvasive method for accurately estimating stroke volume in ischaemic cardiogenic shock"],"prefix":"10.1177","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-5630-3065","authenticated-orcid":false,"given":"Hazem","family":"Lashin","sequence":"first","affiliation":[{"name":"Adult Critical Care Unit, Barts Heart Centre, St Bartholomew\u2019s Hospital, London, UK"},{"name":"William Harvey Research Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olusegun","family":"Olusanya","sequence":"additional","affiliation":[{"name":"Adult Critical Care Unit, Barts Heart Centre, St Bartholomew\u2019s Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrew","family":"Smith","sequence":"additional","affiliation":[{"name":"Adult Critical Care Unit, Barts Heart Centre, St Bartholomew\u2019s Hospital, London, UK"},{"name":"William Harvey Research Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sanjeev","family":"Bhattacharyya","sequence":"additional","affiliation":[{"name":"William Harvey Research Institute, Barts and the London School of Medicine and Dentistry, Queen Mary University of London, London, UK"},{"name":"Cardiology Department, Barts Heart Centre, St Bartholomew\u2019s Hospital, London, UK"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,5,8]]},"reference":[{"key":"e_1_3_2_2_2","doi-asserted-by":"publisher","DOI":"10.1097\/CCM.0000000000003422"},{"key":"e_1_3_2_3_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.chest.2017.08.022"},{"key":"e_1_3_2_4_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.jvca.2022.05.009"},{"key":"e_1_3_2_5_2","doi-asserted-by":"publisher","DOI":"10.1053\/j.jvca.2024.07.024"},{"key":"e_1_3_2_6_2","doi-asserted-by":"publisher","DOI":"10.1186\/cc7129"},{"key":"e_1_3_2_7_2","doi-asserted-by":"publisher","DOI":"10.1530\/ERP-20-0035"},{"key":"e_1_3_2_8_2","doi-asserted-by":"publisher","DOI":"10.1186\/s43044-024-00544-9"},{"key":"e_1_3_2_9_2","doi-asserted-by":"publisher","DOI":"10.1093\/ehjci\/jev014"},{"key":"e_1_3_2_10_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejcts.2006.03.002"}],"container-title":["Journal of the Intensive Care Society"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/17511437251338609","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/full-xml\/10.1177\/17511437251338609","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/journals.sagepub.com\/doi\/pdf\/10.1177\/17511437251338609","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,4,29]],"date-time":"2026-04-29T10:55:25Z","timestamp":1777460125000},"score":1,"resource":{"primary":{"URL":"https:\/\/journals.sagepub.com\/doi\/10.1177\/17511437251338609"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2025,5,8]]},"references-count":9,"journal-issue":{"issue":"4","published-print":{"date-parts":[[2025,11]]}},"alternative-id":["10.1177\/17511437251338609"],"URL":"https:\/\/doi.org\/10.1177\/17511437251338609","relation":{},"ISSN":["1751-1437","1751-1437"],"issn-type":[{"value":"1751-1437","type":"print"},{"value":"1751-1437","type":"electronic"}],"subject":[],"published":{"date-parts":[[2025,5,8]]}}}
