High-sensitivity C-reactive protein mediates age-related vascular dysfunction: the Rotterdam study

Eur J Prev CardiolPublished

  • Cohort study with mediation analysis and two-sample Mendelian randomisation
  • population-based (Rotterdam Study)
  • sex-stratified

Authors' conclusion

Systemic inflammation indexed by hsCRP appears to mediate and potentially contribute causally to age-related vascular stiffness, particularly in men.

Study context

Population
Rotterdam Study participants with longitudinal carotid intima-media thickness (cIMT) or cross-sectional pulse wave velocity (PWV) data7,591 cIMT
Outcome
Mediation by hsCRP of the effect of age on vascular dysfunction (cIMT, PWV)

Main finding

As reported in the abstract

Proportion of age effect mediated by hsCRP

High-sensitivity C-reactive protein (hsCRP) mediated age effect on cIMT (P = 0.001)

2.66%

hsCRP mediated age effect on PWV (P = 4.95 × 10-9)

2.56%

Observational data: associations, not effects.

Further findings

Mendelian randomization (MR): causal effect of hsCRP on vascular outcomes

Genetic support for potential causal relationship between hsCRP and PWV, but not cIMT
