BACKGROUND AND AIMS: Endothelial glycocalyx covers the endothelium and maintains vascular integrity. However, its association with the severity and vulnerability of coronary artery disease (CAD) remains to be elucidated.
METHODS: A total of 259 consecutive patients with stable CAD requiring percutaneous coronary intervention (PCI) were prospectively enrolled. Patients were classified into 2 groups according to the median value of serum syndecan-1, which is a core component of the endothelial glycocalyx (lower syndecan-1 group [syndecan-1 <99.0 ng/mL], n = 130; higher syndecan-1 group [syndecan-1 ≥99.0 ng/mL], n = 129). Severity of CAD and focal plaque vulnerability in culprit lesion were evaluated using angiography and optical coherence tomography.
RESULTS: There was no significant difference in clinical characteristics between the lower syndecan-1 group and the higher syndecan-1 group other than the prevalence of family history of CAD (19 vs. 32%, p = 0.022), prior PCI history (45 vs. 60%, p = 0.015) and estimated glomerular filtration rate (57.8 ± 17.2 vs. 50.9 ± 25.6 ml/min/1.73 m2, p = 0.011). Although disease severity on angiogram was comparable between the 2 groups, the prevalence of lipid-rich plaque (40 vs. 19%, p = 0.004) and thin-cap fibroatheroma (20 vs. 6%, p = 0.006) was significantly higher in the lower syndecan-1 group than the higher syndecan-1 group. Lower syndecan-1 level was independently associated with higher prevalence of lipid-rich plaque (odds ratio 3.626, 95% confidence interval 1.535-8.566, p = 0.003).
CONCLUSIONS: Lower syndecan-1 level was associated with higher prevalence of vulnerable plaque in patients with CAD. This finding suggests the association between impaired endothelial glycocalyx and the development of vulnerable plaque.
