About this study
Official title: Detection and Longitudinal Follow-up of Non-calcified and Calcified Coronary Lesions in Heterozygous Familial Hypercholesterolemia (DESTINY-FH)
This multicenter, non-randomized interventional study aims to assess coronary artery disease progression over 5 years in patients with genetically confirmed heterozygous familial hypercholesterolemia (HeFH), using coronary computed tomography angiography (CCTA).
The primary endpoint is the visual evaluation of coronary stenosis using CAD-RADS v2.0, identifying changes between baseline (2018-2022) and study inclusion. The study will enroll 300 patients (100 protected, 200 non-protected) from La Pitié-Salpêtrière hospital and Saint Antoine Hospital (Paris). Participation lasts up to one week. Total study duration is 2 years, with extended follow-up through routine care data over 10 years.
Read the detailed description
HeFH is an autosomal dominant genetic disorder characterized by lifelong elevated LDL-C levels, which significantly increase the risk of premature coronary atherosclerosis. Cardiovascular risk stratification in HeFH remains challenging due to limitations of traditional risk scores and stress testing. The coronary artery calcium (CAC) score is a useful tool for reclassifying cardiovascular risk but fails to detect non-calcified plaques, which may be prevalent in HeFH despite a CAC score of zero. Previous studies suggest a prevalence of non-calcified plaques as high as 30% in molecularly diagnosed HeFH patients.
This multicenter interventional, non-randomized comparative study aims to evaluate the progression of coronary artery disease over a 5-year period in patients with genetically confirmed heterozygous familial hypercholesterolemia (HeFH). Using coronary computed tomography angiography (CCTA), the study will assess both calcified and non-calcified plaque burden in this high-risk population.
The primary outcome is the visual, semi-quantitative evaluation of coronary stenosis severity using CAD-RADS v2.0 classification to identify high-risk plaques and categorize patients as having regression, stability, or progression of coronary disease based on changes in CAD-RADS categories between baseline (2018-2022) and the DESTINY-FH study visit.
The study will enroll 300 patients (100 "protected" and 200 "non-protected") from La Pitié-Salpêtrière hospital and Saint Antoine Hospital (Paris). Individual participation will last from one day to one week. Total study duration is 2 years, with additional 10-year follow-up using routinely collected medical records.
