Incidence and Predictors of Recurrent Stroke in Cryptogenic Stroke Patients With Atrial Fibrillation

This observational study involved the use of standard cardiac monitoring methods to detect atrial fibrillation in patients initially diagnosed with cryptogenic ischemic stroke. Monitoring techniques included 12-lead ECG, 24-hour Holter monitoring, and implantable loop recorders (ILRs). No experimental interventions were assigned; patients received routine clinical care.
