[Atrial fibrillation--epidemiologic, economic and individual burden of disease].

Atrial fibrillation (AF) is the most frequent cardiac arrhythmia. AF affects especially the elderly. The incidence rises with increasing age to over 15% for those over 90 years old. AF is a risk factor for systemic embolism and ischemic stroke. Stroke with AF is more severe with regard to neurologic impairment. In the management of AF an anticoagulation is essential. However, only half of the patients benefit from anticoagulation in therapeutic target ranges. Costs associated with AF accrue to 660 to 924 Mio Euro in Germany with hospitalization being the major cost contributor. Management of stroke patients with AF is at 3000 Euro higher compared to those patients without AF. AF has an impact on patients' wellbeing and impairs patients' quality of life, particularly the symptomatic form. With an increasing ageing of the society it is suggested to ensure that care management for patients with AF will be optimized. Georg Thieme Verlag KG Stuttgart New York.
