Eur Heart JPublished

  • Retrospective cohort study
  • national family cascade screening programme

Authors' conclusion

Cholesterol-based screening approaches for FH only seem feasible from 1 year of age onward.

Study context

Population
Newborns and children 1–12 years in the Norwegian national familial hypercholesterolaemia (FH) family cascade screening programme, 1998–2023113 newborns
Exposure
FH vs non-FH children
Outcome
Cholesterol-based (LDL-C) screening efficacy for FH

Main finding

As reported in the abstract

LDL-C in newborns (umbilical cord)
GroupValueDetected by 95th percentile cut-offDetected by 85th percentile cut-off
FH1.22 (not stated .48) mmol/L55.7%75.4%
non-FH.68 (not stated .32) mmol/L
  • FH vs non-FH: P < 0.001 — overlapped widely

Observational data: associations, not effects.

Did not differ in subgroups

LDL-C screening in children 1-12 years

LDL-C discriminated highly between FH and non-FH children
