Stroke of Unknown Cause in Women: The Impact of Long-term Heart Monitoring on Stroke Recurrence

The goal of this observational study is to investigate sex - differences in detection rate of atrial fibrillation after cryptogenic stroke (embolic stroke of unknown cause) - using an implantable cardiac rhythm monitor - and the treatment effects of oral anticoagulation on recurrent stroke, ischemic cardiovascular events, major bleeding risk, disability and mortality. The main questions to answer are: * Is long-term monitoring and detection of atrial fibrillation after stroke of unknown cause in women related to recurrent stroke and disability? * Is long-term monitoring and initiation of oral anticoagulation related to cardiovascular events and intracranial haemorrhages? And in addition increased in women compared to men? * Is long-term rhythm monitoring after stroke with unknown cause related to patient reported outcomes in women?
