Independence of Lipoprotein(a) and Low-Density Lipoprotein Cholesterol–Mediated Cardiovascular Risk: A Participant-Level Meta-Analysis

CirculationPublished

  • Participant-level meta-analysis of placebo-controlled statin trials

Authors' conclusion

These findings demonstrate the independent and additive nature of Lp(a) and LDL-C levels for ASCVD risk, and that LDL-C lowering does not fully offset Lp(a)-mediated risk.

Study context

Population
Participants enrolled in 6 placebo-controlled statin trials
Participants
27,658 participants · 6 statin trials
Comparison
Lp >50 mg/dL vs ≤50 mg/dL, by low-density lipoprotein cholesterol (LDL-C) level
Outcome
ASCVD (fatal or nonfatal CHD events, stroke, or any coronary or carotid revascularization)

Pooled result

As reported in the abstract

ASCVD risk by Lp(a) and achieved LDL-C (statin-treated)
Lp(a) >50 mg/dL vs Lp(a) ≤50 mg/dLHazard ratio (95% CI)
lowest quartile of achieved LDL-C (3.1-77.0 mg/dL)
1.38(1.06–1.79)
with LDL-C in fourth quartile; greatest risk
1.90(1.46–2.48)
