Atrial fibrillation (AF) is the most common form of sustained arrhythmia in elderly patients. However, AF is often detected during health screening, or accidentally during testing for other diseases; some patients lack clinical symptoms. Nevertheless, AF increases the incidence of ischemic stroke and other thrombotic events, and compromises cardiovascular prognosis in terms of heart failure, dementia, and hospitalization. Therefore, initial AF management should be performed at the point of primary care, not only in specialized medical centers. We wish to propose a five-step management protocol for AF. We review the evidence supporting integrated management by primary care physicians new to AF, and by specialized physicians who often diagnose and manage AF. Further, we also outline a structured goal-based follow-up protocol; this is an important part of integrated management. (Korean J Med 2018;93:336-343)
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
