It was determined whether they were receiving prior antithrombotic treatment.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>RESULTS<\/jats:title>\n                  <jats:p>Atrial fibrillation was known before stroke in 148 patients (69.5%). Of 213 patients, 34 (16.0%) were receiving anticoagulation treatment before stroke, but only six had an international normalised ratio between 2.0 and 3.5; 65 (30.5%) were receiving antiplatelet treatment; and three (1.4%) were receiving both anticoagulation and antiplatelet treatment. Of 137 patients eligible for oral anticoagulation, 108 (78.8%) did not receive treatment. Of 142 patients eligible for any antithrombotic treatment, 62 (43.7%) were not treated. The logistic regression analysis, assuming anticoagulation treatment as a dependent variable, found digoxin treatment, absence of arterial hypertension, mitral stenosis, and cardioversion as independent factors. Assuming any antithrombotic treatment as a dependent variable, previously known atrial fibrillation, lower age, being a non-smoker, and absence of arterial hypertension were found to be independent factors.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>CONCLUSION<\/jats:title>\n                  <jats:p>More than half of the patients with atrial fibrillation admitted for acute stroke or TIA were not receiving any antithrombotic treatment beforehand. New onset atrial fibrillation and contraindications account for a minority of non-prescriptions; thus, other reasons should be identified to improve stroke prevention in the community.<\/jats:p>\n               <\/jats:sec>","DOI":"10.1136\/hrt.82.5.563","type":"journal-article","created":{"date-parts":[[2014,10,22]],"date-time":"2014-10-22T15:31:45Z","timestamp":1413991905000},"page":"563-569","update-policy":"https:\/\/doi.org\/10.1136\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":31,"title":["Stroke and atrial fibrillation: is stroke prevention treatment appropriate beforehand?"],"prefix":"10.1136","volume":"82","author":[{"given":"D","family":"Deplanque","sequence":"first","affiliation":[{"name":"aDepartment of Neurology, Stroke Unit, University of Lille, Roger Salengro Hospital, F-59037 Lille, France, \n\nbUniversity of Perugia, Via Enrico dal Pozzo, I-06126 Perugia, Italy, \n\ncSainte-Anne Hospital, 1 rue Cabanis F-75674 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"F","family":"Corea","sequence":"additional","affiliation":[{"name":"aDepartment of Neurology, Stroke Unit, University of Lille, Roger Salengro Hospital, F-59037 Lille, France, \n\nbUniversity of Perugia, Via Enrico dal Pozzo, I-06126 Perugia, Italy, \n\ncSainte-Anne Hospital, 1 rue Cabanis F-75674 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"C","family":"Arquizan","sequence":"additional","affiliation":[{"name":"aDepartment of Neurology, Stroke Unit, University of Lille, Roger Salengro Hospital, F-59037 Lille, France, \n\nbUniversity of Perugia, Via Enrico dal Pozzo, I-06126 Perugia, Italy, \n\ncSainte-Anne Hospital, 1 rue Cabanis F-75674 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"L","family":"Parnetti","sequence":"additional","affiliation":[{"name":"aDepartment of Neurology, Stroke Unit, University of Lille, Roger Salengro Hospital, F-59037 Lille, France, \n\nbUniversity of Perugia, Via Enrico dal Pozzo, I-06126 Perugia, Italy, \n\ncSainte-Anne Hospital, 1 rue Cabanis F-75674 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"J L","family":"Mas","sequence":"additional","affiliation":[{"name":"aDepartment of Neurology, Stroke Unit, University of Lille, Roger Salengro Hospital, F-59037 Lille, France, \n\nbUniversity of Perugia, Via Enrico dal Pozzo, I-06126 Perugia, Italy, \n\ncSainte-Anne Hospital, 1 rue Cabanis F-75674 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"V","family":"Gallai","sequence":"additional","affiliation":[{"name":"aDepartment of Neurology, Stroke Unit, University of Lille, Roger Salengro Hospital, F-59037 Lille, France, \n\nbUniversity of Perugia, Via Enrico dal Pozzo, I-06126 Perugia, Italy, \n\ncSainte-Anne Hospital, 1 rue Cabanis F-75674 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D","family":"Leys","sequence":"additional","affiliation":[{"name":"aDepartment of Neurology, Stroke Unit, University of Lille, Roger Salengro Hospital, F-59037 Lille, France, \n\nbUniversity of Perugia, Via Enrico dal Pozzo, I-06126 Perugia, Italy, \n\ncSainte-Anne Hospital, 1 rue Cabanis F-75674 Paris, France"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"the SAFE I Study Investigators","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"239","published-online":{"date-parts":[[1999,11,1]]},"reference":[{"key":"2025100707310622000_82.5.563.1","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.22.3.312"},{"key":"2025100707310622000_82.5.563.2","doi-asserted-by":"publisher","DOI":"10.1212\/WNL.28.10.973"},{"key":"2025100707310622000_82.5.563.3","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.27.10.1760"},{"key":"2025100707310622000_82.5.563.4","doi-asserted-by":"publisher","DOI":"10.1161\/01.STR.27.10.1760"},{"key":"2025100707310622000_82.5.563.5","doi-asserted-by":"crossref","first-page":"1","DOI":"10.7326\/0003-4819-116-1-1","article-title":"Predictors of thromboembolism in atrial fibrillation: part I.
