| Brief Title | Cardiac Amyloidosis : Diagnostic Using Red Flag Signals | ||||||||
| Official Title | Early Echographic Screening of Cardiac Amyloidosis Using Red Flag Signals | ||||||||
| Brief Summary | Cardiac amyloidosis is an increasingly contributor of degenerative cardiac diseases. However, its frequency remains underestimated, and diagnosis is often realized at late stages of the disease. A larger use of clinical and echographic Red Flag signals during routine echocardiographic examination may enhance the identification of early stage of the disease. | ||||||||
| Detailed Description | The objective is to evaluate the clinical and epidemiological aspects of cardiac amyloidosis using a systematic screening of even moderate left ventricular hypertrophy, taking into account the presence of Red Flag signals. Red Flag Signals will include history or symptoms of carpal tunnel syndrome, hearing loss, chronic gastrointestinal disorders, heart failure, cervical or lumbar stenosis, or echographic abnormalities such as apical sparring, increased left ventricular filling pressure, atrio-ventricular block. | ||||||||

| Study Population | Caribbeans who the large share of populations from African origin may be associated with a high prevalence of Transthyretin amyloidosis. In this population, diagnosis procedure will be perform to any patient with Left Ventricular Hypertrophy (LVH) with wall thickness ? 12 mm associated with clinical manifestations (or Red Flag signals | ||||||||
