Quality of life in patients with atrial fibrillation.

Atrial fibrillation (AF) is a frequent and costly health care problem. In patients with AF, the restoration and maintenance of sinus rhythm is the primary therapeutic goal. The most frequent strategy for maintaining sinus rhythm after restoration is the use of antiarrhythmic drugs. The efficacy of therapy in AF has been predominantly measured using objective criteria such as mortality and morbidity. In recent years, the importance of quality of life (QoL) as an outcome measure has been recognized. However, few studies in the literature have examined QoL in patients with AF using properly validated tools. In addition, the specific impact of antiarrhythmic drug treatment on QoL in patients with AF has not been assessed. These issues are now being addressed in several ongoing studies. This article attempts to define QoL, makes recommendations on how QoL might be assessed, reviews our current knowledge regarding QoL in patients with AF, and discusses new clinical trials currently assessing QoL in patients with AF.
