Epidemiología de la fibrilación auricular

Atrial fibrillation is the most common sustained cardiac arrhythmia in the general population. In Spain, the latest data suggest that the prevalence in people aged over 40 years could be greater than 4%. Both the prevalence and incidence of atrial fibrillation have increased substantially over time. Possible reasons for this rise are the aging of the population, an increase in the number of cardiovascular risk factors and better cardiovascular disease survival. In addition, the increased availability of improved diagnostic tools for detecting atrial fibrillation could have contributed. This article provides a review of the evidence available on the epidemiology of atrial fibrillation in Spain and other western countries.
