简要总结
Amyloidosis is a disease caused by the continuous accumulation of fibrillary proteins in the extracellular matrix causing the architecture of different organs to be disrupted. The prevalence of the disease increases with age. The two most common forms are light chain amyloidosis (AL) and transthyretin (TTR). TTR amyloidosis may be hereditary (m-TTR, or mutated) or age-related (WT-TTR, or wild). The latter is also called senile amyloidosis. In all these forms, cardiac impairment is common and leads the patient to consult/or be referred to a cardiological center unfortunately often too late when the prognosis is directly related to the severity of the heart attack. The description/discovery of clinical signs prior to heart disease is important to improve the detection and diagnosis of early forms of cardiac amyloidosis (CA). For example, an infiltration of the carpal tunnel synovial by amyloid deposits is observed in some patients, 5 years before the onset of signs of heart failure and is the only warning sign of the disease known to date. We also showed in a previous study that patients had more severe and earlier impairment of hearing function than expected by age and gender.
Objective The main objective is to define the prevalence and severity of smell and taste disorders in a population of patients with cardiac amyloidosis (3 types of mutated or wild AL amyloidosis and TTR).
The main endpoint is to determine the number of patients with impaired smell and taste's functions in a population of patients diagnosed with cardiac amyloidosis (3 types of mutated (hereditary) or senile wild amyloidosis (3 types of AL amyloidosis and TTR).
Method Successive monocentric cross-sectional study on the screening of smell and taste disorders carried out as part of a cardiology hospitalization programmed for the cardiology follow-up of his pathology in a population of patients diagnosed with AC.

时间窗: at inclusion day
Prevalence of smell and taste disorders in a population of patients with cardiac amyloidosis
时间窗: at inclusion day
次要结局
- correlation between type of amyloidosis (AL, TTR mutated and wild type) and Sniffin's stick test TDI's score (/48)(at inclusion day)
- Date of onset of smell and taste disorder (month/years) compared with date of onset of cardiological symptoms and cardiac amyloidosis, based on declarative assessment(at inclusion day)
- Correlation between nutritional depletion and Sniffin's stick test TDI scores (/48). Nutritional depletion is evaluated by BMI (Body mass index kg/m2), brachial circumference (cm), tricipital fold (mm), orosomucoid g/L(at inclusion day)
- TDI scores of Sniffin's stick test compared to Sniffin's stick test TDI scores of age and gender-matched subjects(at inclusion day)
- Correlation between severity of cardiac amyloidosis and and Sniffin's stick test TDI's score (/48). Severity of cardiac amyloidosis is evaluated by clinical characteristics (NYHA, Heart rate (bpm), Systolic Blood Pressure (mmHg), Diastolic Blood Pressure(at inclusion day)
