A combined subgroup analysis of the similar trials NOAH – AFNET 6 (1) and ARTESiA (2) revealed: Patients with device-detected atrial fibrillation and concomitant vascular disease are at higher risk of stroke and cardiovascular events and may derive a greater benefit from oral anticoagulation than those without vascular disease. The finding was presented by AFNET Steering Committee member Prof. Renate Schnabel, University Medical Center Hamburg-Eppendorf (UKE), Hamburg, Germany, at the annual congress of the European Society of Cardiology (ESC) in London on 02.09.2024 and published in the European Heart Journal (3).
Device-detected atrial fibrillation (DDAF) are short and typically rare episodes of atrial fibrillation (AF) detected by pacemakers, defibrillators, or implanted loop recorders. Device-detected atrial fibrillation is found in every fifth patient with a cardiac implanted electronic device (4). Device-detected atrial fibrillation can lead to stroke, but the stroke risk in patients with device-detected atrial fibrillation appears lower than the stroke risk in patients with ECG-documented atrial fibrillation (1%/year).
