Twenty-three percent (82 of 353) had atrial fibrillation or flutter on their admission electrocardiogram. This group differed significantly from that with sinus rhythm in three respects: 1) They were older (p less than 0.01); 2) they had more severe current stroke deficit as evidenced by lower limb power (p less than 0.05) and Mini-Mental State Score (p less than 0.001), higher incidence of homonomous hemianopia (p less than 0.05), and lower incidence of lacunar syndrome stroke (p less than 0.001); and 3) they had a significantly higher incidence of cardiomegaly and congestive heart failure (p less than 0.01). Functional outcome was insignificantly better in the group with sinus rhythm. During a mean follow-up period of 18 months, mortality was significantly higher in the group with atrial fibrillation (p = 0.001). Proportional hazards modeling, however, showed that the apparently poorer survival in those patients with atrial fibrillation could be explained by factors other than cardiac rhythm, such as age, Mini-Mental State Score, level of consciousness, and interstitial edema on admission chest radiograph. Thus, atrial fibrillation was not an independent predictor of survival after stroke.<\/jats:p>","DOI":"10.1161\/01.str.22.2.209","type":"journal-article","created":{"date-parts":[[2011,6,17]],"date-time":"2011-06-17T20:08:03Z","timestamp":1308341283000},"page":"209-214","update-policy":"https:\/\/doi.org\/10.1161\/crossmarkpolicy","source":"Crossref","is-referenced-by-count":18,"title":["Atrial fibrillation after stroke in the elderly."],"prefix":"10.1161","volume":"22","author":[{"given":"P J","family":"Friedman","sequence":"first","affiliation":[{"name":"Stroke Unit, Waikato Hospital, Hamilton, New Zealand."}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"276","container-title":["Stroke"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.ahajournals.org\/doi\/pdf\/10.1161\/01.STR.22.2.209","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2024,5,12]],"date-time":"2024-05-12T22:08:51Z","timestamp":1715551731000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.ahajournals.org\/doi\/10.1161\/01.STR.22.2.209"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[1991,2]]},"references-count":0,"journal-issue":{"issue":"2","published-print":{"date-parts":[[1991,2]]}},"alternative-id":["10.1161\/01.STR.22.2.209"],"URL":"https:\/\/doi.org\/10.1161\/01.str.22.2.209","relation":{},"ISSN":["0039-2499","1524-4628"],"issn-type":[{"value":"0039-2499","type":"print"},{"value":"1524-4628","type":"electronic"}],"subject":[],"published":{"date-parts":[[1991,2]]},"assertion":[{"value":"1991-02-01","order":2,"name":"published","label":"Published","group":{"name":"publication_history","label":"Publication History"}}]}}
