Evaluation of Ambulatory ECG Telemetry for the Early Detection of Atrial Fibrillation During Hospital Assessment of Cerebral Infarction

Study Overview
=================
Brief Summary
-----------------
The aim of the study is to show that an ambulatory ECG telemetry monitoring of some patients hospitalized for cerebral infarction increases the frequency of the diagnosis of atrial fibrillation, cause of their stroke, and reinforces the protection against recurrences.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: holter-ECG<br>Implementation of an ECG Holter during hospitalisation patient. | Device: ECG telemetry<br>* ECG telemetry (holter ECG) is a portable case - attached to the belt or around the neck - connected to 6 electrodes placed on the skin next to the heart. They are worn by patients during their stay in hospital<br>|
| No Intervention: Crontrole<br>No implementation of an ECG Holter | |

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Diagnostic impact of outpatient ECG telemetry | Percentage of patients hospitalized for cerebral infarction and with a diagnosis of atrial fibrillation allowed by the use of ambulatory ECG telemetry. | 6 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Identification of prognostic factors to identify de novo atrial fibrillation | Retrospective evaluation of prognostic criteria (clinical data, biomarkers, abdominal MRI) in patients with a diagnosis of AF | 6 months | 
| Evaluate the therapeutic impact (prescription anticoagulant) at the end of hospitalisation | Percentage of patients on anticoagulation at the end of hospitalisation | 6 months | 
| Evaluate the benefit on the recurrence rate of cerebral infarction after the exit of the service | Percentage of IC recurrence in the department and within 3 months of the IC diagnosis | 3 months |
