  • Retrospective cohort study
  • 2 medical centres

Authors' conclusion

In a large, contemporary U.S. cohort, elevated Lp(a) is independently associated with long-term MACE among individuals with and without baseline ASCVD.

Study context

Population
Patients with Lp(a) measured at 2 medical centres in Boston, Massachusetts, 2000–2019, with or without baseline atherosclerotic cardiovascular disease (ASCVD)
Participants
16,419 patients
Exposure
Lp percentile groups vs 1st–50th percentile
Outcome
Incident MACE:
  • Nonfatal MI
  • Nonfatal stroke
  • Coronary revascularization
  • CV mortality
Follow-up
Median 11.9 years

Main finding

As reported in the abstract

MACE
71st to 90th percentile vs 1st to 50th percentile · baseline ASCVD (n = 10,181)
adjusted HR 1.21; P < 0.001
91st to 100th percentile vs 1st to 50th percentile · baseline ASCVD (n = 10,181)
adjusted HR 1.26; P < 0.001
91st to 100th percentile vs 1st to 50th percentile · no established ASCVD (n = 6,238)
adjusted HR 1.93; P < 0.001

Observational data: associations, not effects.
