This is a clinical registry of patients with cardiac amyloidosis being treated at University Hospital Leipzig. The aim of the registry is to collect detailed information about clinical events, symptoms, imaging, biomarkers, comorbidities, and treatment from routine patient management which would not be provided by randomized clinical trails.
Cardiac amyloidosis is increasingly diagnosed since awareness of the disease and therapeutic options increase. There is evidence from clinical trials about warning signs ("red flags"), diagnostic algorithms, and evidence for specific treatment. However, patients in randomized clinical studies are highly selected and do not necessarily reflect clinical practise. Furthermore, large clinical trials do not account for national medical care differences nor provide data about long-term outcome and the associations with comorbidities.
Clinical registries may reflect broad clinical practise and help to characterize cardiac amyloidosis in terms of epidemiology, application of diagnostic methods, the impact of comorbidities, and real-world clinical course. Furthermore, clinical registry studies may validate data from randomized clinical trials, provide information on implementation of treatment, the quality of interventions, monitoring patients during treatment, and inform about the safety of procedures.
The cardiac amyloidosis registry aims to collect data from the routine clinical management of patients with cardiac amyloidosis at the tertiary care University Hospital Leipzig. In particular, obtaining data about clinical events of heart disease, hemodynamic measures from echocardiography and circulation biomarkers, cardiac morphology from different imaging methods, clinical status, functional capacity, quality of life, and impact of comorbidities during the course of the disease will be the goal of this registry.
