摘要

摘要: 目的：探讨多层螺旋CT （MSCT）的心血管参数联合收缩压（SBP）对诊断肺动脉高压（PH）的预测价值。方法：回顾性分析84例经右心导管检查确诊为PH患者的MSCT心血管参数和临床记录。根据PH诊断标准分为实验组和对照组，比较2组患者的MSCT心血管参数和血压的差异性。按时间顺序，设前56例的数据为推导队列，推导多重线性回归模型，此方程基于主肺动脉与升主动脉直径的比值（rPA）、脊柱室间隔夹角（Septal angle）和SBP预测平均肺动脉压（MPAP）。采用受试者工作特征曲线（receiver operating characteristic curve，ROC）曲线比较这3个单因素与模型的诊断效能。后29例患者作为验证队列，用于进行前瞻性验证回归模型的准确性。结果：本研究推导的MPAP计算方程是：MPAP=9.011+34.195×rPA+0.402×Septal angle-0.319×SBP，其曲线下面积（AUC）为0.925，95%置信区间（CI）为0.848~1.000。与单独应用rPA、Septal angle、SBP相比，联合应用具有最高的预测价值。前瞻性验证中MPAP预测值与右心导管数值接近，其93.10%预测值的差值在95%一致性界限以内。结论：联合应用rPA、Septal angle、SBP有助于对PH进行评估，并为PH的临床治疗提供指导。

Abstract: Objective: This study was aimed to investigate the predictive value of cardiovascular parameters of multi-slice spiral computed tomography(MSCT) scan and systolic blood pressure(SBP) in the diagnosis of pulmonary hypertension(PH).Method: A retrospective analysis of cardiovascular parameters of MSCT and clinical data was performed in 84 patients diagnosed as PH by right heart catheterization.The patients were divided into experimental group and control group according to the PH diagnostic criteria, and the differences in MSCT cardiovascular parameters and blood pressure between the two groups were compared.In chronological order, based on rPA, septal angle and SBP, a multiple linear regression equation was generated from the first 56 patients' data to estimate the mean pressure of pulmonary artery(MPAP).The ROC curve was used to compare the diagnostic efficiency amongst these three single factors and this model.The last 29 patients' data were used to test the accuracy of the model prospectively.Result: The computed equation for analyzing MPAP is MPAP=9.011+34.195×rPA+0.402×Septal angle-0.319×SBP.Its AUC was 0.925 with 95%CI(0.848-1.000).Compared with the use of rPA, septal angle and SBP individually, the combined use of them has the highest predictive value.The predicted value of MPAP in the validation cohort was close to that of right heart catheterization.Its subtraction was 93.10% in the 95% limits of agreement.The difference of the predicted value of 93.10% was within the 95% consistency limit.Conclusion: The combined use of rPA, septal angle and SBP helps to evaluate PH and provides guidance for clinical treatment.
