Résumé

{Background: Since atrial fibrillation (AF) may be undiagnosed when asymptomatic and paroxysmal, we aimed to investigate the incidence and determinants of silent AF in patients with acute ischemic stroke or transient ischemic attack (TIA). Methods: Consecutive patients admitted to the Stroke Unit of the University Hospital of Dijon, France, for acute ischemic stroke or TIA were prospectively enrolled from March to December 2012. Silent AF was assessed by continuous electrocardiography (ECG) monitoring for 24 h after admission. An echocardiography was performed at day 2 +/- 1 to measure left ventricular ejection fraction (LVEF) and left auricular (LA) dimensions. Results: Among the 187 patients included, 19 (10%) developed silent AF. Patients with silent AF were markedly older (76 vs. 66 years, p < 0.002), with lower creatinine levels (90 vs. 80 mu mol/l
