What this trial studies

This observational registry aims to collect real-world data on the diagnostic process, management, and outcomes of patients diagnosed with cardiac AL or ATTR amyloidosis. By evaluating the progression of the disease and identifying clinical and echocardiographic predictors of prognosis, the study seeks to enhance understanding of this underdiagnosed condition. Patients over 18 years old who meet specific diagnostic criteria will be included, and their health outcomes will be monitored over time. The study will help inform treatment strategies and improve patient care.

Who should consider this trial

Good fit: Ideal candidates for this registry are adults over 18 years old diagnosed with cardiac AL or ATTR amyloidosis.

Not a fit: Patients who do not meet the diagnostic criteria for cardiac amyloidosis or are unable to provide informed consent may not benefit from this study.

Why it matters

Potential benefit: If successful, this registry could lead to improved diagnosis and treatment strategies for patients with cardiac amyloidosis.

How similar studies have performed: Other studies have shown success in collecting real-world data for similar conditions, indicating that this approach is promising.

* negative hematological test and bone scintigraphy Perugini stage 1 and histological confirmation (either extracardiac or cardiac biopsy) with subtyping of ATTR amyloidosis
* positive hematological test and bone scintigraphy Perugini stage 1-3 and histological confirmation (usually cardiac biopsy) with subtyping of ATTR amyloidosis
