摘要：目的：探讨血浆硫酸吲哚酚（IS）水平对不稳定型心绞痛（UA）的诊断价值及其与冠状动脉斑块负荷的相关性。方法：收集接受冠状动脉造影的患者372例，其中UA患者177例（UA组）、冠状动脉粥样硬化（CAS）患者120例（CAS组）及冠状动脉造影未见异常者75例（对照组）。应用靶向快速分辨液相色谱质谱法检测血浆中IS水平。应用心脏外科与介入治疗狭窄冠状动脉研究（SYNTAX）评分量化冠状动脉斑块负荷。结果：UA组患者血浆IS水平高于CAS组及对照组（P均＜0.05）。多因素Logistic回归分析显示IS是罹患UA的独立危险因素（OR=2.90，95%CI：1.89~4.44，P＜0.001）。趋势性检验中，依据IS三分位数，将IS分为T1、T2、T3组，在校正混杂因素后，UA患病风险随血浆IS水平升高而逐渐增加 [OR（95% CI）：T2 vs. T1：1.99（1.13~3.50），P=0.018；T3 vs. T1：5.18（2.88~9.29），P＜0.001；趋势性检验P＜0.001]。IS预测UA的受试者工作特征（ROC）曲线下面积为0.69（95%CI：0.63~0.74，P＜0.001）。IS水平与UA患者SYNTAX评分呈正相关（r=0.52, P＜0.001）。多因素Logistic回归显示IS（OR=4.34，95%CI: 2.27~8.31，P＜0.001）是UA患者中/高SYNTAX评分的危险因素。结论：IS是诊断UA的独立预测因子，且与UA患者冠状动脉斑块负荷严重程度呈正相关。

Abstract Objective: To evaluate the diagnostic value of indoxyl sulfate (IS) in unstable angina pectoris (UA) and its correlation with coronary atherosclerotic plaque burden. Methods: A total of 372 patients who underwent coronary angiography were selected consecutively. The selected patients were divided into three groups: UA group (177 cases), coronary atherosclerosis (CAS) group (120 cases) and control group (75 cases). The levels of plasma IS were determined by targeted liquid chromatography/mass spectrometry. Coronary atherosclerotic burden was quantified using the Synergy Between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score. Results: The plasma IS levels in the UA group were higher than those in CAS group and control group (P< 0.05). Multivariate logistic regression analysis showed that IS (OR=2.90, 95% CI: 1.89-4.44, P= 0.001) was a risk factor for UA. After adjusting for confounding factors in the linear trend test, the risk of UA increased gradually with rising plasma IS levels [OR (95% CI): T2 vs. T1: 1.99 (1.13-3.50), P=0.018; T3 vs. T1: 5.18 (2.88-9.29), P<0.001; P for trend <0.001]. The area under the ROC curve predicted by IS for UA was 0.69 (95% CI: 0.63-0.74, P<0.001). The level of IS was positively correlated with the SYNTAX score of UA patients (r= 0.52, P< 0.001). Multivariate logistic regression showed IS (OR=4.34, 95%CI: 2.27-8.31, P<0.001) was a risk factor for the medium/high SYNTAX score of the patients with UA. Conclusions: IS is an independent predictor for diagnosing UA and is positively correlated with the severity of coronary atherosclerotic burden in UA patients.
