Investigating the association of innovative serum inflammatory markers and atypical lipid profiles with in-stent restenosis following percutaneous coronary intervention: a retrospective analysis from a single center
Clinical Report: Innovative Serum Inflammatory Markers and ISR Post-PCI
Overview
This study investigates the association of novel inflammatory markers and atypical lipid profiles with in-stent restenosis (ISR) following percutaneous coronary intervention (PCI). Key findings indicate that CRI-II and LCI are independent risk factors for ISR.
Background
In-stent restenosis (ISR) remains a significant challenge in the management of coronary heart disease despite advancements in drug-eluting stents (DES). Accurate identification of biomarkers for ISR is crucial, as ISR can lead to recurrent cardiovascular events and necessitate repeated revascularization. Understanding the role of inflammation and lipid metabolism in ISR pathogenesis is essential.

Key Findings
Higher levels of SII, SIRI, NLR, PLR, MLR, PIV, CRI-II, and LCI were observed in the ISR group compared to the non-ISR group (all P < 0.05).
CRI-II was identified as an independent risk factor for ISR with an odds ratio of 1.277 (95% CI: 1.066–1.529, p = 0.008).
LCI was also an independent risk factor for ISR with an odds ratio of 1.010 (95% CI: 1.002–1.018, p = 0.020).
ROC analysis indicated CRI-II had an AUC of 0.586 and LCI had an AUC of 0.571.
No novel serum inflammatory markers were independently associated with ISR in multivariate analysis.
Clinical Implications
The study highlights the need for further research to validate the predictive value of CRI-II and LCI in clinical settings. Clinicians should remain cautious in utilizing these biomarkers for ISR risk stratification until more robust evidence is available.
Conclusion
CRI-II and LCI show statistical associations with ISR after PCI, but their discriminatory ability is limited.
