Patients were categorized into four groups based on past medical history and admission electrocardiogram: (1) no (neither past nor current), (2) incident (newly diagnosed), (3) past and (4) chronic (past and current) atrial fibrillation. The primary outcome was 4-year all-cause mortality. Bivariate and multivariable Cox proportion hazards analyses were used to determine risk of all-cause mortality. In the multivariable model, we adjusted for various demographic and clinical covariates. Compared with patients who never had atrial fibrillation, those with incident atrial fibrillation had a 57% higher risk of death (unadjusted hazard ratio, 1.57; 95% confidence interval, 1.22\u20132.03). After adjustment for other covariates the association remained unchanged (adjusted hazard ratio, 1.41; 95% confidence interval, 1.08\u20131.83). Past or chronic atrial fibrillation was not associated with increased risk of death.<\/jats:p>","DOI":"10.1016\/j.ejheart.2004.12.004","type":"journal-article","created":{"date-parts":[[2005,4,9]],"date-time":"2005-04-09T07:57:04Z","timestamp":1113033424000},"page":"1118-1121","source":"Crossref","is-referenced-by-count":28,"title":["Incident Atrial Fibrillation and Mortality in Older Adults with Heart Failure"],"prefix":"10.1093","volume":"7","author":[{"given":"Ali","family":"Ahmed","sequence":"first","affiliation":[{"name":"Division of Gerontology and Geriatric Medicine, Department of Medicine, School of Medicine , Birmingham, AL ,","place":["United States"]},{"name":"Department of Epidemiology, School of Public Health, University of Alabama at Birmingham , Birmingham, AL ,","place":["United States"]},{"name":"Section of Geriatrics, Veterans Affairs Medical Center , Birmingham, AL ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gilbert J.","family":"Perry","sequence":"additional","affiliation":[{"name":"Division of Cardiovascular Disease, Department of Medicine, School of Medicine , Birmingham, AL ,","place":["United States"]},{"name":"Section of Cardiology, Veterans Affairs Medical Center , Birmingham, AL ,","place":["United States"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"286","published-online":{"date-parts":[[2005,12,22]]},"reference":[{"issue":"4","key":"2026020203571573300_ejhf2004-12-004-bib-0001","doi-asserted-by":"crossref","first-page":"421","DOI":"10.1016\/j.ejheart.2003.11.011","article-title":"Impact of atrial fibrillation on mortality and readmission in older adults hospitalized with heart failure","volume":"6","author":"Ahmed","year":"2004","journal-title":"Eur.
