About this trial
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.
