NCT05569356

Brief Summary

This study aims to identify novel inflammatory biomarkers in AC, whether in circulating blood, in situ or as imaging biomarkers to better understand the pathophysiology of the disease and then to determine contribution to the clinical management of patients.

Outcome Measures

Primary Outcomes (1)

  • Measure the correlation between the autoimmunity, inflammatory, and immunological profiles through biomarkers found in blood samples, myocardial biopsies, mass imaging cytometry, and cardiac imaging in patients with Arrhythmogenic Cardiomyopathy (AC)

    10 years

Secondary Outcomes (7)

  • Measure the correlation between circulating biomarkers and the severity of the phenotype determined by the severity of AC and multi-modality imaging

    10 years

  • Measure the correlation between imaging biomarkers and electrocardiogram (ECG) parameters (presence of repolarization and depolarization abnormalities)

    10 years

  • Measure the changes in inflammatory biomarkers in serum and cardiac imaging over time

    10 years

  • Demonstrate a correlation between circulating and imaging biomarkers and the link between the extent of fibro-adipose infiltrates and the ventricular strain

    10 years

  • Measure the correlation between circulating and imaging biomarker values and electro-anatomical mapping data

    10 years

  • +2 more secondary outcomes

Eligibility Criteria

Age18 Years - 100 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)
Sampling MethodNon-Probability Sample
Study Population

All adult patients with clinical or preclinical Arrhythmogenic Cardiomyopathy (carrier of risk mutation). The retrospective patients will be informed by mail and the prospective patients will be informed during their routine care visit, both using the opt-out approach.

You may qualify if:

  • Adult patient (age ≥ 18 years old)
  • Patient with a probable or confirmed diagnosis of cardiomyopathy according to the diagnostic criteria of the international task force
  • Patient carrying a pathogenic mutation responsible for cardiomyopathy
  • Patient informed individually of the research

You may not qualify if:

  • Patients under curatorship/guardianship
  • Pregnant women
  • Patients who expressed their opposition to participate in the study
