Echocardiographic Standards and Sub-Saharian Africans (SSA) Migrants' in New Aquitaine Region

Study Overview
=================
Brief Summary
-----------------
Standards Echocardiographic have been defined mainly on caucasian or Asian populations. In the EchoNoRMAL study the criteria for African populations were based solely on data from 198 subjects. This study suggests the presence of different standards depending on the ethnic origin of the subjects. The aims of this study is to describe the proportion of subjects reclassified (normal-pathological) according to the use of echocardiographic norm differences showed in TAHES population (Sub Saharian Africans) with those routinely used

Detailed Description
-----------------
Sub-Saharian Africans populations seem to be more vulnerable in the field of health in general and in cardiovascular pathologies in particular. The echocardiographic standards were mainly defined for Caucasian or Asian populations (EchoNoRMAL col. 2014 and 2015). In the EchoNoRMAL study, the criteria for the African populations were based on a reduced workforce (data from 198 subjects). This study suggests the presence of different standards depending on the ethnic origin of the subjects. The authors noted that the establishment of references according to the ethnic origin of the subjects is necessary and highlighted the need for additional study for the underrepresented groups, in particular those including subjects of African origin. The need for different ECG standards in African subjects, was confirmed in a study in the general African population (TAHES), represents 16% of immigrants in 2015 (INSEE According to reports from the health insurance funds, the migrant population,

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: African migrant's population located in la region New Aquitaine.<br>Echocardiography norms will be harvested data on SSA participants located in la region New Aquitaine, France | Diagnostic Test: Echocardiography measures on SSA participants<br>* Upon SSA Subject is admitted to the hospital for an echocardiography, Information about this study process, Participants will receive an information note ; Administration of a medical history questionnaire, collection of cardiovascular risk factors, weight toe (all of which are routinely collected before an echocardiographic examination is performed); Performing and recording the echocardiographic examination according to routine protocol delivery of the results according to the usual management; deferred analysis of the recordings on workstation with classification of the data (normal-pathological) according to the different standards<br>|

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

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Proportion of subjects reclassified (from pathological to normal) according to the echocardiographic standard used (reference standard vs. TAHES standard). | Compare the echocardiography standards previously established in TAHES study to those used routinely managed for the population of SSA migrants in la region New Aquitaine, in order to define pathological subjects | 18 months | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Describe the reasons of reclassification, based on the change of echocardiography standards use for the following criteria: left ventricular hypertrophy, left atrial dilatation, aortic dilatation, ascending, right ventricular dilatation | Identification and analyse the number of subjects requalified from pathological to normal) and identify reasons of the reclassifications after the use of the standards | 18 months |
