Abstract :

Atrial fibrillation is a very common diagnosis which currently affects nearly 3 million adults in the United States with a projected doubling of the prevalence by the year 2050. The prevalence of atrial fibrillation increases dramatically with age in both men and women with greater than 10% of individuals over the age of 80 years carrying the diagnosis. Morbidity and mortality of patients with atrial fibrillation is largely due to the associated increased risk of thromboembolic complications, especially stroke. Atrial fibrillation is associated with a nearly five-fold increased risk of stroke and is a stronger risk factor than hypertension, coronary disease, or heart failure. The vast majority of strokes in atrial fibrillation are due to emboli arising from left atrial appendage thrombi caused by blood flow stasis in a fibrillating atrium. In addition to the increased risk, strokes occurring in patients with atrial fibrillation are more debilitating, are more likely to recur, and are associated with worse survival as compared to stroke patients without atrial fibrillation. As will be discussed in this review, managing stroke risk in patients with atrial fibrillation is challenging and requires accurate assessment of stroke risk factors and careful selection of appropriate therapy. The cornerstone of therapy for decades has been, and continues to be, anticoagulation with warfarin being the standard agent until the recent introduction of novel anticoagulants, which will be reviewed in detail. In addition, emerging non-pharmacologic interventions may play an important role in mitigating stroke risk in AF in the future.
