  • Registry-based cohort study

Authors' conclusion

First-degree relatives of individuals with elevated Lp(a) levels have a higher incidence of MACE.

Study context

Population
First-degree relatives aged 35–69 years without a measured Lp(a), of indexes with a routine plasma Lp(a) measurement, Swedish STRIREG cohort41,304 indexes
