Asymptomatic versus symptomatic atrial fibrillation: A systematic review of age/gender differences and cardiovascular outcomes

摘要

Up to 40% of atrial fibrillation (AF) patients are asymptomatic. Despite this, scarce data are available about asymptomatic AF, with regard to its clinical profile and relationship to cerebrovascular and cardiovascular risks. Our objective was to conduct a systematic review and meta-analysis was to study the relationship between age and gender with asymptomatic AF and to establish whether patients with asymptomatic AF have a higher risk of death (all-cause and cardiovascular) and stroke/systemic thromboembolism, when compared to symptomatic AF patients.
