The Care of Patients With Atrial Fibrillation and Heart Failure

Atrial fibrillation (AF) and heart failure (HF) are the 2 emerging epidemics in global cardiovascular disease. AF remains the most common cardiac arrhythmia, affecting over 33 million adults worldwide, and continues to increase in prevalence as the populations of many nations age. The prevalence of HF also surges, now afflicting 37 million adults globally. Interestingly, these 2 disease processes share many of the same risk factors and stem from many of the same pathophysiologic derangements, with AF occurring in over half of all patients with HF and HF occurring in over one third of all patients with AF. Furthermore, exacerbation of one of these ailments often drives decompensation or compromises therapy of the other, and it has been widely reported that coexistence of AF in patients with HF portends a poorer prognosis. As a result, many clinicians now routinely face the problem of AF in the patient with HF. In this review, we highlight the fundamental pathologic forces embedded in the relationship between AF and HF and then proceed to a discussion on the management of these complex patients with a detailed exploration of the clinical data.
