Risk-weighted apolipoprotein B (apoB): a novel summary metric outperforming traditional lipid biomarkers in predicting coronary heart disease

Eur Heart JPublished

  • Prognostic model development and validation study
  • UK Biobank derivation
  • 3 other population cohorts

Authors' conclusion

RW-apoB represents not only particle number but also accounts for the higher atherogenicity of TRL and Lp(a). It offers clinically meaningful improvements in CHD risk stratification.

Study context

Population
UK Biobank and three other large population cohorts
Comparison
RW-apoB vs measured apoB for coronary heart disease (CHD) risk prediction

Performance

As reported in the abstract

CHD risk prediction

Individuals up- or down-ranked by ≥10 percentiles vs ranking by measured apoB

52%

Further findings

CHD event rate by reclassification

Top RW-apoB quintile with elevated TRL and Lp(a), about one-third misclassified as lower risk by apoB: CHD event rate
5.4%
Top measured apoB quintile with low TRL and Lp(a), correctly down-ranked: CHD event rate
3.9%

Residual risk in statin-treated subjects

RW-apoB potentially a better index of residual risk
