Local vs systemic inflammation and outcomes after percutaneous coronary intervention
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 patients2,436 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

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
