Authors' conclusion

The cascade screening strategy for familial hypercholesterolaemia is associated with 51% fewer cardiovascular events in genetically confirmed heFH probably due to an earlier age at treatment initiation.

Study context

Population
Patients with molecularly diagnosed heterozygous familial hypercholesterolaemia, French FH registry REFERCHOL
Participants
3,232 patients
Exposure
Cascade screening vs opportunistic screening for heterozygous familial hypercholesterolaemia (HeFH)
  • Cascade screening casesn = 1,126
  • Index casesn = 2,106reference
Outcome
Cardiovascular events (ASCVD)

Main finding

As reported in the abstract

ASCVD
  • Cascade screening independently associated with 51% less atherosclerotic cardiovascular disease (ASCVD) than opportunistic screening (multivariate logistic regression)

Observational data: associations, not effects.

Further findings

CV event prior to first visit

P < 0.001

Age at statin initiation · statin started earlier

difference 14 · P < 0.001

ASCVD in age- and sex-matched analysis

Cascade screening no longer associated with ASCVD; age at statin initiation remained associated
  • age- and sex-matched analysis

Age at statin initiation and ASCVD

Higher adjusted OR for ASCVD with higher age categories at statin initiation
