High-density lipoprotein (HDL)-associated sphingosine-1-phosphate (S1P) contributed to several beneficial effects in the cardiovascular system. We explored the relationship between the HDL-S1P concentrations and coronary in-stent restenosis (ISR).
Fifty consecutive patients with ISR and 50 normal control subjects were included. The serum S1P, HDL-S1P and clinical data were collected to explore the relationships between these parameters and ISR.
The patients with ISR had significantly lower concentrations of serum S1P (96.10 ± 26.33 vs. 113.40 ± 32.72; P = 0.004) and HDL-S1P (32.81 ± 10.02 vs. 42.72 ± 11.75; P < 0.001). All included patients were divided into four quartiles based on their concentrations of HDL-S1P: Quartile 1 (18.63-28.51 ng/ml), Quartile 2 (28.62-37.28 ng/ml), Quartile 3 (37.35-45.27 ng/ml), and Quartile 4 (45.59-79.36 ng/ml). The rates of ISR were 84%, 48%, 40% and 28%, respectively. The patients in Quartile 1 exhibited significantly higher rates of ISR compared with the other groups (P = 0.001). A multivariate stepwise logistic regression analysis indicated that HDL-S1P (OR = 0.846, 95% CI = 0.767-0.932, P = 0.001) was an independent predictor of ISR. An ROC analysis indicated that HDL-S1P = 30.37 ng/ml and had a 90% sensitivity and a 52% specificity in predicting ISR.
HDL-S1P is an independent predictor of ISR, and patients with higher concentrations of HDL-S1P have a low risk of ISR.
高密度脂蛋白（HDL）相关的1-磷酸鞘氨醇（S1P）对心血管系统有多种有益作用。我们探讨了HDL-S1P浓度与冠状动脉支架内再狭窄（ISR）之间的关系。
纳入50例连续的ISR患者和50例正常对照者。收集血清S1P、HDL-S1P及临床资料，以探讨这些参数与ISR之间的关系。
ISR患者的血清S1P浓度（96.10±26.33对113.40±32.72；P = 0.004）和HDL-S1P浓度（32.81±10.02对42.72±11.75；P < 0.001）显著降低。根据HDL-S1P浓度将所有纳入患者分为四个四分位数：四分位数1（18.63 - 28.51 ng/ml）、四分位数2（28.62 - 37.28 ng/ml）、四分位数3（37.35 - 45.27 ng/ml）和四分位数4（45.59 - 79.36 ng/ml）。ISR发生率分别为84%、48%、40%和28%。四分位数1的患者与其他组相比，ISR发生率显著更高（P = 0.001）。多因素逐步逻辑回归分析表明，HDL-S1P（OR = 0.846，95%CI = 0.767 - 0.932，P = 0.001）是ISR的独立预测因子。ROC分析表明，HDL-S1P = 30.37 ng/ml，在预测ISR时敏感性为90%，特异性为52%。
HDL-S1P是ISR的独立预测因子，HDL-S1P浓度较高的患者ISR风险较低。
