MINNEAPOLIS & BERLIN--(BUSINESS WIRE)--Each year, approximately 795,000 people experience a new or recurrent stroke1 in the United States, and approximately a half million people in Western Europe are similarly afflicted2. Today, Medtronic, Inc. (NYSE: MDT) announces two significant clinical trials related to medical device interventions for stroke. First enrollments in the global CRYSTAL AF (Study of Continuous Cardiac Monitoring to Assess Atrial Fibrillation After Cryptogenic Stroke) trial have taken place. The trial will use the Reveal® XT Insertable Cardiac Monitor (ICM) to assess the incidence of atrial fibrillation (AF) in patients with cryptogenic stroke (stroke of an undetermined cause) or transient ischemic attack (TIA) in order to aid physicians in determining the optimal course of treatment for these patients. It is widely recognized that patients with sustained AF are at increased risk of stroke3.
