Abstract:

目的探讨Wells评分与D-二聚体对急性肺栓塞(APE)的预测价值。 方法选取2013年10月至2014年10月间我院急诊危重症中心经多层螺旋CT肺动脉造影(CTPA)和(或)放射性核素肺通气-灌注扫描确诊的82例住院的APE患者作为APE组,同期选取胸痛中心有类似症状而临床排除APE诊断的82例患者作为对照组。将这两组患者在住院当日分别进行Wells评分,记录患者住院当日D-二聚体、pH、PCO2、PO2、P(A-a)O2、脑钠肽、肌钙蛋白I,并将混杂因素进行多变量Logistic回归分析,筛选出相关变量。计算相关变量受试者工作特征(ROC)曲线下面积(AUC),以敏感性为纵坐标,1-特异性为横坐标,制作ROC曲线,选择最佳临界值,计算敏感性、特异性、阳性预测值(PPV)、阴性预测值(NPV)。 结果多变量Logistic回归分析结果显示,能够早期预测APE的指标有Wells评分(OR=8.114,95%CI 1.894~34.761,P=0.005)和D-二聚体(OR=1.009,95%CI 1.001~1.017,P=0.021)。Wells评分对APE患者早期预测的AUC、敏感性、特异性、PPV、NPV分别为0.990、50.0%、100.0%、100.0%、66.7%。D-二聚体对APE患者早期预测的AUC、敏感性、特异性、PPV、NPV分别为0.986、95.1%、97.6%、97.5%、95.2%。 结论Wells评分和D-二聚体检测简便易行,对APE有较高的预测价值,可用于急诊筛查APE患者
