Characterization of Patients With Cardiomyopathy to Identify Critical Patients Candidates for Cardiac Transplantation

The study aims to identify new diagnostic and prognostic markers for CMP that can help predict disease progression. In particular, the study will focus on microRNAs (miRNAs) and spatial transcriptomics, which are emerging techniques that may provide insights into the underlying disease mechanisms. By understanding these markers, the investigators hope to improve the way the investigators diagnose and manage CMP, particularly in terms of predicting progression to heart failure or heart transplantation. The study will evaluate patients with hypertrophic cardiomyopathy (e.g., sarcomeric forms, Anderson-Fabry disease, AL, and TTR cardiac amyloidosis), dilated cardiomyopathy and arrhythmogenic cardiomyopathy. These patients will undergo clinical evaluations, including ECG, echocardiograms, CMR, biopsy analysis, and genetic testing, as well as molecular studies such as transcriptomics and miRNA analysis. This comprehensive approach aims to identify potential new biomarkers for diagnosing and predicting the disease course.
