Chronic atrial fibrillation: Incidence, prevalence, and prediction of stroke using the Congestive heart failure, Hypertension, Age >75, Diabetes mellitus, and prior Stroke or transient ischemic attack (CHADS2) risk stratification scheme.
The aim of the study is to estimate the incidence and prevalence of chronic AF (cAF) in the United Kingdom and test the accuracy of the CHADS2 score for stroke prediction. ⋯ Atrial fibrillation is a prevalent and growing problem, which significantly increases the risk of ischemic stroke. The CHADS2 score is a good predictor of the stroke risk but could be improved.
