The aim of the study is to assess the prevalence of AF, anticoagulation management, and risk of stroke/transient ischaemic attack (TIA) in patients with cardiomyopathy. Three thousand two hundred eight consecutive adult patients with cardiomyopathy (34.9% female; median age: 55.0 years) were prospectively enrolled as part of the EURObservational Research Programme Cardiomyopathy/Myocarditis Registry. At baseline, 903 (28.2%) patients had AF (29.4% dilated, 27.5% hypertrophic, 51.5% restrictive, and 14.7% arrhythmogenic right ventricular cardiomyopathy, P  The study reveals a high prevalence and diverse distribution of AF in patients with cardiomyopathies, inadequate anticoagulation regimen, and high risk of stroke/TIA in this population.enAttribution-NonCommercial-NoDerivatives 4.0 Internationalhttp://creativecommons.org/licenses/by-nc-nd/4.0/AnticoagulationArrhythmogenic right ventricular cardiomyopathyAtrial fibrillationDilated cardiomyopathyHypertrophic cardiomyopathyRestrictive cardiomyopathyresearch article32940421open access10.1002/ehf2.128542055-5822PMC7754739https://doi.org/10.1002/ehf2.12854https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7754739/pdf
