Background Endothelial dysfunction plays an important role in the pathophysiology of coronary artery disease (CAD). Previous studies suggested that human endothelial cell-specific molecule-1 (endocan) may be a novel endothelial dysfunction marker. This study aims to investigate the relationship between serum endocan level and the presence and severity of CAD in patients with hypertension.
Methods A total of 190 eligible hypertension patients were enrolled in this study. Serum endocan level was measured by enzyme-linked immunosorbent assay. The presence and severity of CAD were evaluated by coronary angiography.
Results Hypertensive patients with CAD had significantly higher serum endocan level than those without CAD (1.63 ± 0.51 ng/mL vs 1.31 ± 0.65 ng/mL, P < 0.05). Multivariate logistic regression revealed that serum endocan level was independently associated with the presence of CAD (odds ratio, 2.662; 95% confidence interval, 1.560–4.544; P < 0.001). Spearman rank correlation analysis demonstrated that serum endocan level was associated with SYNergy between PCI with TAXUS and Cardiac Surgery score (r = 0.349, P = 0.001).
Conclusions Serum endocan level is independently correlated with the presence and severity of CAD in hypertension patients, and those with high endocan level may have an increased risk of developing atherosclerosis.
