摘要:

目的 探讨血管性血友病因子裂解酶(ADAMTS-13)识别高危非ST段抬高型心肌梗死(NSTEMI)的价值。方法 选取NSTEMI患者142例(NSTEMI组),以冠状动脉造影正常的非冠心病患者50例作为对照组。收集所有患者的基线资料、临床信息和实验室检测结果[血肌酐(Cr)、高敏肌钙蛋白I(hs-cTnI)、血小板(PLT)计数、D-二聚体(DD)],采用荧光共振能量转移(FRET)技术检测血浆ADAMTS-13活性。根据NSTEMI患者入院时的全球急性冠状动脉事件注册(GRACE)评分将患者分为低危组(43例)、中危组(54例)和高危组(45例)。采用Spearman秩相关分析评估ADAMTS-13活性与NSTEMI危险分层的相关性。采用二元Logistic回归分析评估高危NSTEMI的影响因素。采用受试者工作特征(ROC)曲线评估ADAMTS-13判断高危NSTEMI的效能。结果 NSTEMI组血浆ADAMTS-13活性低于对照组(P<0.001)。低危组、中危组及高危组血浆ADAMTS-13活性依次降低(P<0.001)。Spearman秩相关分析结果显示,ADAMTS-13活性与NSTEMI患者危险分层呈负相关(rs=-0.527,P<0.001)。二元Logistic回归分析结果显示,ADAMTS-13是高危NSTEMI的保护因素[比值比(OR)=0.936,95%可信区间(CI)为0.898~0.975],年龄、心率、Cr和Killip分级≥Ⅱ级均是高危NSTEMI的危险因素(OR值分别为1.148、1.085、1.023、26.207,95%CI分别为1.047~1.259、1.023~1.150、1.004~1.041、5.489~125.136)。ROC曲线分析结果显示,ADAMTS-13判断高危NSTEMI的曲线下面积(AUC)为0.784,最佳临界值为 61.7%,敏感性为71.1%,特异性为81.4%。结论 ADAMTS-13活性与NSTEMI的危险分层有关,对高危NSTEMI具有较好的判断价值。

Abstract:

Objective To investigate the clinical role of a disintegrin and metalloproteinase with thrombospondin motif 13(ADAMTS-13)in identifying high-risk non-ST-segment elevation myocardial infarction(NSTEMI). Methods ADAMTS-13 activity determination was performed on the samples collected from 142 patients with NSTEMI(NSTEMI group) through a fluorescence resonance energy transfer(FRET)-based assay. Totally,50 non-coronary heart disease patients with normal coronary angiography were enrolled as control group during the same period. The baseline information,clinical data and determination results [creatinine(Cr),high-sensitivity cardiac troponin I(hs-cTnI),platelet(PLT) count,D-dimer(DD)] were collected. According to the Global Registry of Acute Coronary Events(GRACE)score at admission,the NSTEMI patients were classified into low-risk group(43 cases),medium-risk group(54 cases)and high-risk group(45 cases). Spearman rank correlation analysis was used to analyze the correlation between ADAMTS-13 activity and risk stratification in NSTEMI patients. Binary Logistic regression analysis was used to investigate the influencing factors for high-risk NSTEMI. Receiver operating characteristic(ROC)curve was used to evaluate the clinical value of ADAMTS-13 on high-risk NSTEMI. Results The ADAMTS-13 activity in NSTEMI group was lower than that in control group(P<0.001),and it was decreased from low-risk,medium-risk to high-risk groups(P<0.01). Spearman rank correlation analysis results showed that,ADAMTS-13 activity was negatively correlated with risk stratification in NSTEMI patients(rs=-0.527,P<0.001 ). Binary Logistic regression analysis showed that ADAMTS-13 was a protective factor [odds ratio(OR)=0.936,95% confidence interval(CI) 0.898-0.975]. Age,heart rate,Cr and Killip grading ≥Ⅱ were risk factors(OR=1.148,1.085,1.023 and 26.207,95%CI 1.047-1.259,1.023-1.150,1.004-1.041 and 5.489-125.136). ROC curve analysis indicated that the area under curve(AUC) of ADAMTS-13 activity in predicting high-risk NSTEMI was 0.784. When the optimal cut-off value was 61.7%,the sensitivity and specificity were 71.1% and 81.4%,respectively. Conclusions ADAMTS-13 activity is related to the risk stratification of NSTEMI,which has clinical value in the diagnosis of high-risk NSTEMI.
