Brief description/objective

Incidence of Silent Atrial Fibrillation in Patients With Clinically Silent Brain Ischemic Lesions

Arterial Fibrillation (AF) is well-recognized as a cause for cryptogenic Acute Ischemic Stroke (AIS) and is associated with Silent Brain Infarction (SBI). However, the role of AF in the formation of lesions (SBIs) is less well established than its role in AIS and needs clarification.

The investigators hypothesize that continuous rhythm monitoring will yield a similar incidence of AF diagnosis in patients with SBI as compared to patients with cryptogenic AIS.

The primary objective is to assess the cumulative incidence of AF diagnosis at 24 months in patients with SBI.
