Acute Ischemic Stroke Management

Undetected cardiac embolism by Atrial Fibrillation (AF) is responsible for a substantial number of ischemic strokes classified as cryptogenic.Current guidelines recommend electrocardiographic monitoring for the first 24-48 hours after hospital admission.The authors intended to evaluate the number of new onset AF identified by telemetry in patients with transient ischemic attack (TIA) / ischemic stroke, without other etiology identified, in a stroke unit, and its characterization.Material and Methods: Patients admitted in a type C unite stroke from May to December 2015 were included in the study and selected those diagnosed with TIA / stroke without identified etiology, without know AF or documented on admission of the current hospitalization, and who had electrocardiographic register by telemetry for a minimum period of 24 hours.The medical team was responsible for reviewing telemetry data with the purpose of AF identification.Data analysis was performed with SPSS v23.Results: Of 217 patients admitted in our stroke unit, 79 were selected.The mean age was 73.9 years and 53,2% were male.70 patients had an ischemic stroke (88.6%) and 9 patients had a TIA (11.4%).Of the 79 patients, in 12 (15.2%)was identified AF rhythm in the telemetry data (paroxysmal AF: 11; persistent AF: 1) and of these, 11 (91%) patients had their therapeutic strategy altered through initiation of anticoagulation therapy.Discussion: The number of AF detected in this series was similar to the data from other studies.Telemetry is an important exam in the diagnosis of AF in patients with ischemic stroke, that otherwise, could be defined as cryptogenic.The electrocardiographic recording by telemetry permits an earlier and correct therapeutic approach.
