Brief Summary

CONCERTO is a retrospective, observational, multicentric and single-arm study to perform an external validation of the cloud-based and AI-powered electrocardiogram (ECG) analysis platform, named Willem™, to detect Transthyretin cardiac amyloidosis (ATTR-CA). Thus, this study will assess Willem™ ability to distinguish between truly diagnosed ATTR-CA patients and confirmed non-ATTR-CA patients from ECG data.

Conditions

Transthyretin Cardiac Amyloidosis

Keywords

Transthyretin cardiac amyloidosis; ATTR; AI-based ECG Analysis

Outcome Measures

Primary Outcomes (1)

• Device performance

  Assessment of Willem ability to distinguish between confirmed diagnosed ATTR-CA patients and subjects with no ATTR-CA diagnosis from ECG data of sufficient quality. The diagnostic performance metrics will be accuracy, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and F1-score.

  Baseline (closest clinical assessment to ATTR-CA diagnosis)

Secondary Outcomes (1)

• Device performance with sub-optimal ECG data quality

  Baseline (closest clinical assessment to ATTR-CA diagnosis)

Study Arms (2)

ATTR-CA patients

Adult patients with confirmed diagnosis of ATTR-CA

Controls (non ATTR-CA subjects)

Adult subjects suspected of ATTR-CA, but finally confirmed not to have ATTR-CA

Eligibility Criteria

• Age: 18 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Subjects with a suspected or confirmed diagnosis of ATTR-CA

You may qualify if:

• Subjects ≥ 18 years old
• Subjects with 12-leads ECG records with a 10 seconds minimum length on digital format

You may not qualify if:

• Patients with paced rhythm on the ECG.
