Descripción
Inclusion Criteria:
- 1. Participant must be 18 years and older at the time of signing the informed consent form.
- 2. Participants with either of the following:
- - Positive ATTR-CM cases: Participants with a clinical diagnosis of transthyretin amyloid cardiomyopathy (ATTR-CM) with amyloid deposits in cardiac or non-cardiac tissue confirmed by Congo Red (or equivalent) staining, or DPD-Tc, PYP-Tc, or HMDP-Tc scintigraphy with Grade 2 or 3 cardiac uptake in the absence of abnormal light chains ratio.
- - Control population: Participants with a clinical diagnosis of guideline-directed medical therapy-directed heart failure (HF) and either:
- a) Subgroup A: Definitively excluded ATTR-CM amyloidosis: negative cardiac or non-cardiac tissue biopsy for amyloid, or negative technetium scintigraphy within the past 2 years.
- b) Subgroup B: Low probability of ATTR-CM amyloidosis, not definitively excluded: absence of amyloid-suggestive features on echocardiography (ECHO), electrocardiography (ECG), or cardiac magnetic resonance imaging (MRI) within the past 2 years, with documented clinical assessment indicating HF etiology unlikely attributable to amyloidosis; no amyloid-specific testing (technetium scintigraphy or biopsy) performed.
- 3. Participant or legally authorized representative (LAR) must sign the informed consent form.
Exclusion Criteria:
- 1. Any known eye condition that may preclude clear imaging of the retina.
- 2. Any known history of amyloid light-chain (AL) amyloidosis.
- 3. Any ocular surgery that, in the opinion of the investigator, makes participation in the study undesirable.
- 4. Any medical condition that, in the opinion of the investigator, makes participation in the study undesirable, for example, if the participant is critically unwell or requires ongoing emergency treatment.
- 5. Involvement in the planning and/or conduct of the study.
- 6. In the opinion of the investigator, the participant is unlikely to comply with study procedures, restrictions, and requirements.
- 7. Previous enrollment in the present study.

Sensitivity, specificity, and Area Under the Receiver Operating Characteristic Curve (AUROC) of the ML model to correctly identify ATTR-CM cases based on ocular imaging data
Periodo de tiempo: At a single assessment time point within 90 days following informed consent form signing
|
Sensitivity, specificity, and area under the receiver operating characteristic curve will be used to describe the performance of the machine learning model for distinguishing participants with clinically confirmed transthyretin amyloid cardiomyopathy (ATTR-CM) from heart failure controls without ATTR-CM based on ocular imaging data.

Descripción del plan IPD
Qualified researchers can request access to anonymized individual patient-level data from AstraZeneca group of companies sponsored clinical trials via the request portal Vivli.org. All requests will be evaluated as per the AZ disclosure commitment: https://astrazenecagrouptrials.pharmacm.com/ST/Submission/Disclosure.
Yes, indicates that AZ are accepting requests for IPD, but this does not mean all requests will be shared.
