  • mediation analysis

Authors' conclusion

Plasma remnant cholesterol levels are independently associated with systemic inflammation and cardiovascular events. Inflammation, as measured with hsCRP, contributed minorly to the association between remnant cholesterol and MACE.

Study context

Population
Participants without prior atherosclerotic CVD from the EPIC-Norfolk study (mean age 58.8 ± 9.1 years; 56.9% women)
Participants
16,445 participants
Exposure
Remnant cholesterol vs low-density lipoprotein (LDL) cholesterol
Outcome
Proportion of the effect of remnant and LDL cholesterol on (non)fatal MACE (CAD and ischaemic stroke) mediated by inflammation (hsCRP)

Main finding

As reported in the abstract

Mediation by hsCRP of the effect on MACE

High-sensitivity C-reactive protein (hsCRP) mediated share of remnant cholesterol effect on major adverse cardiovascular events (MACE)

5.9% (95% CI: 1.2, 10.6%, P < 0.001)

Observational data: associations, not effects.

Further findings

MACE per 1 mmol/L higher cholesterol — LDL cholesterol1.21 (1.13–1.31)P < 0.001
Outcome% higher hsCRP (95% CI)P value
