Predictive Factors for Excellent or Extremely Poor Functional Outcome in Initial Atrial Fibrillation-Related Cardioembolic Stroke

摘要

Background: We aimed to determine the predictive factors for excellent or extremely poor functional outcome in patients with first-ever atrial fibrillation (AF)-related cardioembolic stroke. Methods: Retrospective observational study from a database. Patients with AF-related cardioembolic stroke with a premorbid modified Rankin Scale (mRS) score of 0 or 1 and without a previous history of stroke were included. Results: Factors associated with excellent functional outcome (mRS scores of 0 or 1; n = 77; 30.4 of patients) included age >78 years (OR 0.31, 95 CI 0.15-0.61), male sex (OR 2.16, 95 CI 1.04-4.60), absence of hypertension (OR 0.46, 95 CI 0.22-0.94) and initial National Institutes of Health Stroke Scale (NIHSS) score of >9 (OR 0.08, 95 CI 0.03-0.16). Factors associated with extremely poor functional outcome (mRS scores of 5 or 6; n = 63; 24.9) included age >78 years (OR 3.30, 95 CI 1.54-7.39), initial NIHSS score of >9 (OR 12.38, 95 CI 5.40-32.56), congestive heart failure (OR 4.82, 95 CI 2.00-12.19) and ischemic heart disease (OR 4.02, 95 CI 1.18-14.69). Conclusions: Predictive factors exist to delineate excellent and extremely poor functional outcomes after a first-time stroke associated with AF. (C) 2016 S. Karger AG, Basel
