A contemporary snapshot of familial hypercholesterolemia registries

Familial hypercholesterolemia (FH) registries can capture unique data on FH concerning real-world practice, clinic epidemiology, natural history, cascade testing, cardiovascular consequences of late diagnosis, and use of healthcare resources. Such registries are also valuable for identifying and bridging the gaps between guidelines and clinical practice. We reviewed recent findings from the principal FH registries.

Most adult patients with heterozygous FH (HeFH) are diagnosed late, undertreated, and do not reach guideline-recommended low density lipoprotein-cholesterol (LDL-C) goals. In children and adolescents with HeFH, detection relies principally on genetic testing and measurement of LDL-C levels. Similarly, the majority of patients with homozygous FH (HoFH) receive sub-optimal cholesterol-lowering treatments and do not attain recommended LDL-C goals, gaps being wider in lower income than higher income countries. In HeFH patients, men have a higher risk of atherosclerotic cardiovascular disease than women.

The evolving data from FH registries provide real-world evidence for developing implementation strategies to address gaps across the continuum of care of FH worldwide.
