Abstract
BACKGROUND: Although evidence is not very clear, diabetes is assumed to be an independent risk factor for atrial fibrillation (AF). One reason for the lack of evidence could be that AF often is not detected due to its paroxysmal or asymptomatic character. A better understanding of the relationship between both diseases and improved detection of AF is necessary since the combination of both diseases dramatically increase the risk of strokes if not treated properly. METHODS: Available literature about diabetes as an independent risk factor for AF has been evaluated, and limitations of studies are discussed. RESULTS: Results from different trials and registers are contradictory concerning diabetes as an independent risk factor for AF. Reasons for these differences can be found in different study designs and neglecting patients with unknown AF. CONCLUSIONS: Due to the increasing burden of disease of diabetes and AF as common risk factors for stroke, a systematic screening for AF in diabetes patients could provide a better understanding of their correlation and personalized prevention strategies.
