Cardiac AmyloidosisEARLY-CANCT05693376
Screening Algorithm for Early Detection of Occult Cardiac Amyloidosis
An observational study of Cardiac Amyloidosis, run by University Hospital, Essen at 1 site in Germany.
Trial summary
Early diagnosis of cardiac amyloidosis (CA) is crucial because of the poor overall survival, high mortality and the need for early therapy including new treatment possibilities for transthyretin amyloidosis. Read more about this study

About this study
Official title: Evaluation of a Screening Algorithm for Early Detection of Occult Cardiac Amyloidosis in Subjects at Risk
Early diagnosis of cardiac amyloidosis (CA) is crucial because of the poor overall survival, high mortality and the need for early therapy including new treatment possibilities for transthyretin amyloidosis. Previously considered a rare condition, CA is being demonstrated to account for up to 17 % of heart failure with preserved ejection fraction cases as well as up to 16 % of Patients with severe aortic stenosis, undergoing surgical of transcatheter aortic valve replacement. It seems that CA is being underdiagnosed as the data of post-mortem studies demonstrate that at least 25% of elderly individuals have histologic evidence of amyloid deposits. Other common conditions with increased afterload such as hypertensive or hypertrophic heart disease that mimic echocardiographic features or clinical symptoms may be the reason of postponed recognition of CA. Furthermore, the lack of definitive biomarkers makes the diagnosis even more challenging. However, it has been shown that some clinical, laboratory and echocardiographic findings, so called "red flags", may indicate occult CA. A deeper and constructive analysis of the findings and establishment of prediction criteria could possibly lead to improvement of early CA recognition and survival in subjects at risk. We aim to prospectively perform a systematic screening for CA in individuals at risk based on predefined selection criteria. Our aim is to evaluate if specific criteria would lead to increased detection of CA and in this case, to define major and minor diagnostic criteria.
Read the detailed description
The study aims to perform a prospective screening and detect occult CA in subjects at risk with aortic valve stenosis, undergoing either transcatheter or surgical aortic valve replacement. The study has two main objectives. Firstly, we aim to determine the real prevalence of CA according to the targeted "red flags" analysis and secondly, we aim to establish an algorithm for early detection of CA.
