Coronary disease & ACSCohort study

Local vs systemic inflammation and outcomes after percutaneous coronary intervention

Eur Heart JPublished

  • Prospective cohort study

Authors' conclusion

Local coronary inflammation shows a stronger association with adverse outcomes after PCI than systemic inflammation. Integrating both markers improves risk stratification and may support inflammation-guided management in patients with CAD.

Study context

Population
Patients with coronary artery disease (CAD) undergoing percutaneous coronary intervention (PCI)
Participants
1,987 patients · 2,436 vessels
Exposure
Local coronary inflammation vs systemic inflammation
Outcome
MACE:
  • All-cause mortality
  • Non-fatal MI
  • Unplanned repeat revascularization
Follow-up
median 3-year follow-up

Main finding

As reported in the abstract

Model discrimination

Both markers improved discrimination vs either alone
DeLong P < 0.05

Sensitivity analysis excluding revascularization

Advantage of isolated high FAI-MAX attenuated; dual-high phenotype remained significant
