Coronary disease & ACSSecondary analysis

Balance of non–Lp(a) Apolipoprotein B (apoB) and Lp(a) with Coronary Plaque Phenotypes and MACE: Insights from PROSPECT II and CASABLANCA

Eur J Prev CardiolPublished

  • Secondary analysis of the PROSPECT II study
  • Near-infrared spectroscopy-intravascular ultrasound (NIRS-IVUS)
  • exploratory external cohort (CASABLANCA)

Authors' conclusion

Non-Lp(a) apoB and Lp(a) demonstrate distinct associations with coronary plaque burden and vulnerability.

Study context

Population
Patients with recent MI
Participants
854 patients
Comparison
Non-Lp(a) apoB, Lp(a) and non-Lp(a) apoB/Lp(a) ratio vs coronary plaque burden and vulnerability

Primary result

As reported in the abstract

Plaque burden and vulnerability
Odds ratio (95% CI)P value
Lower non-Lp(a) apoB/Lp(a) ratio tertileplaque burden ≥70%
1.47(1.04–2.07)
P = 0.029
Lower non-Lp(a) apoB/Lp(a) ratio tertilecomposite: plaque burden ≥70% and maxLCBI4mm ≥324.7
1.62(1.12–2.33)
P = 0.011
Higher non-Lp(a) apoB · plaque percentage volume; independent association
β 0.19 (95% CI 0.05–0.33); P = 0.009

Further findings

CASABLANCA external cohort

Lower ratios identified an Lp(a)- and oxidized phospholipid-enriched phenotype and were associated with higher unadjusted CV risk
