Study context

Population
Individuals with homozygous familial hypercholesterolaemia (HoFH) from 45 countries
Participants
over 950 individuals · 45 countries

Main finding

As reported in the abstract

Characteristics at diagnosis: age at diagnosis, untreated LDL-C, ASCVD or (supra)aortic valve disease, LDL-C goal attainment on LLT · at diagnosis

Age at diagnosis, median (IQR 5.5-27.0)

12 years

Untreated low-density lipoprotein cholesterol (LDL-C), median (11.6-18.4)

14.7 mmol/L

Atherosclerotic cardiovascular disease (ASCVD) or (supra)aortic valve disease at diagnosis

9%

Achieved guideline-recommended LDL-C goals despite widespread lipid-lowering therapy (LLT)

4%

Observational data: associations, not effects.

Further findings

Lipoprotein-apheresis timing

Early initiation associated with greater LDL-C reductions and delayed ASCVD onset

Sex differences

No sex differences in age or clinical characteristics at diagnosis, treatment patterns, or timing of ASCVD; usual sex gap in CVD onset absent

Global disparities

Limited genetic screening, restricted access to LLT, and earlier onset of major adverse CV events in non-high-income countries
