Silent Atrial Fibrillation - Screening of High-risk Groups for Atrial Fibrillation (The Silence Study)

The primary aim of the present study is to screen high-risk type 2 diabetes patients and heart failure patients without any history of atrial fibrillation (AF), ongoing oral anticoagulation (OAC) treatment, implanted device or recent stroke/Transient Ischemic Attack (TIA), for silent AF. Moreover, we aim to establish the prevalence of two or more risk factors for stroke in patients with heart failure and diabetes mellitus type 2 (DM2) with the aim of assessing the feasibility for this group to undergo AF screening. Overall, the aim of the study is to prevent stroke in high-risk patients groups through identification of silent (asymptomatic) atrial fibrillation.
