Authors' conclusion

Overall, the addition of polygenic information using PRSCAD percentiles to the FH-Risk-Score estimate did not significantly enhance ASCVD risk prediction in patients with FH.

Study context

Population
Patients with familial hypercholesterolaemia (familial hypercholesterolemia (FH))
Participants
1,438 patients · 3 cohorts
Comparison
FH-Risk-Score plus PRSCAD vs FH-Risk-Score alone
Outcome
Atherosclerotic cardiovascular disease (ASCVD) risk prediction: discrimination (C-index), calibration and reclassification (10-year risk cutoff 20%)
Follow-up
10 years
