Assessment of Cardiac Fibrosis in HCM Using FAPI-PET/MR

Basic Information

Recruitment status Recruiting
Health condition(s) or Problem(s) studiedHypertrophic Cardiomyopathy
Date of first enrollment23/10/2024
Target sample size30
Countries of recruitment
Study typeInterventional
Intervention(s)Perform 68Ga-FAPI PET/MR, contrast-enhanced MRI examinations, and blood sampling.

Outcome(s)

Primary OutcomeFor the total cardiac fibrosis burden in patients with HCM, evaluate the correlation between the amount of fibrosis expressed by FAPI-PET (product of SUVmean and region of interest) in the myocardium as calculated by contrast enhanced cardiac MRI.
Secondary OutcomeTo compare the imaging results of FAPI-PET/MR and conventional contrast enhanced cardiac MRI between severe HCM patients and regular HCM patients, and evaluate the extent of fibrosis or damage indicated by each technique. To assess the correlation between the polygenic score and the imaging results of FAPI-PET/MR and conventional contrast enhanced cardiac MRI in HCM patients (both severe and regular). To evaluate the relationship between risk score for sudden cardiac death score and the imaging results of FAPI-PET/MR and conventional contrast enhanced cardiac MRI between the severe HCM group and the regular HCM group.

Include criteria1) Diagnosed with HCM by a cardiologist, the patient has been enrolled in the "Prospective Registry for Evaluating the Clinical Diagnosis of Hypertrophic Cardiomyopathy (PREVAIL-HCM)" clinical trial, led by Kyoto University. 2) Performed contrast-enhanced cardiac MRI in Kyoto University Hospital
Exclude criteriaPregnant or possibly pregnant.
