Arrhythmogenic Cardiomyopathy

Keywords
Arrhythmogenic Cardiomyopathy, Inflammatory biomarkers, Autoantibodies
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.
Detailed description
The treatment of AC remains based on palliative measures aimed at treating the consequences of the disease: antiarrhythmic treatments, defibrillator, treatments for heart failure. The identification of new biomarkers, in particular circulating ones, would make it possible to open pathophysiology avenues which, in the long term, could lead to therapies targeted to autoimmunity or inflammation. Many scientific and medical questions remain unanswered and require precise databases on the diagnostic and prognostic evaluation of this pathology. The objective of this study is to identify novel inflammatory biomarkers in patients with AC by studying the autoimmunity, inflammatory, and immunological profiles through blood samples and myocardial biopsies.
