The impact of lipoprotein(a) on coronary atherosclerotic plaque phenotype in primary prevention

Eur J Prev CardiolPublished

  • Retrospective cohort study
  • plaque-level analysis
  • AI-based quantitative coronary computed tomography angiography (CCTA) (AI-QCT)

Authors' conclusion

In this plaque-level CCTA study of 3642 individual plaques, elevated Lp(a) levels were independently associated with increased noncalcified plaque volume and with the presence of HRP, but not with calcified plaque volume.

Study context

Population
Patients who underwent coronary CT angiography with Lp(a) measured, 2008–2024 (primary prevention)3,642 plaques
Participants
710 patients
Exposure
Elevated Lp vs lower Lp
Outcome
Association of Lp(a) with noncalcified and calcified plaque volumes and HRP features at the plaque level

Main finding

As reported in the abstract

Plaque phenotype (adjusted plaque-level analysis)

Adjusted odds ratio

1.78

95% CI 1.25–2.54

P = 0.001

Elevated Lp(a) (≥150 nmol/L) vs lower Lp(a)
adjusted OR 1.78 (95% CI 1.25–2.54); P = 0.001
Elevated Lp(a) associated with increased noncalcified plaque volume per plaque
P = 0.009
Elevated Lp(a) not associated with increased calcified plaque volume
P = 0.81

Observational data: associations, not effects.

Further findings

LDL-C and high-sensitivity CRP vs presence of high-risk plaque (HRP)

LDL-C and high-sensitivity CRP not associated with HRP
P > 0.05
