[Silent atrial fibrillation].
Asymptomatic atrial fibrillation (AF) is common, may adversely affect quality of life, and above all can be as serious as symptomatic AF. The prevalence of AF reported in epidemiological studies is significantly underestimated, as asymptomatic AF is often not known about. The efficacy of pharmacological or non-pharmacological treatment is often overestimated if the only aim considered is symptomatic recurrences. Like symptomatic AF, asymptomatic AF justifies anticoagulation, depending on the risk of embolism. Estimating the risk of embolism only from symptomatic episodes may result in unjustified discontinuation of antithrombotic treatment. Finally, frequent asymptomatic episodes may worsen atrial or even ventricular remodelling and result in tachycardia-induced cardiomyopathy.
