Objective To observe value of 0D-1D coupling model and 3D fluid-structure interaction(FSI)model based on coronary CT angiography(CCTA)for displaying hemodynamic characteristics of coronary artery *** Based on CCTA data of the stenosed left anterior descending branch(LAD)in a patient with coronary heart disease,an 0D-1D coupling model and 3D FSI model were built,*** hemodynamic characteristic indexes,including the pressure,flow velocity and wall shear stress(WSS)were obtained in every 0.01 s during 1 s at 5 sampling points(*** point 1—5)using these 2 models,respectively,and the consistencies of the results between models were evaluated with Spearman correlation coefficient r *** The time consuming for construction of 0D-1D coupling model and 3D FSI model was 0.033 min and 704 min,*** models showed basically distribution of the pressure,flow velocity and WSS of the stenosed *** more details,the pressure at the stenosed segment of LAD and the proximal segment of stenosis were both higher,which gradually decreased at the distal segment of stenosis,and the flow velocity at the proximal segment of stenosis was in a relatively slow and uniform condition,with significantly increased flow velocity and WSS at the stenosed *** with 3D FSI model,0D-1D vascular coupling model was relatively unrefined and lack of distal flow lines when displaying blood flow *** sampling point 2 at the stenosed segment of LAD,no significant consistency for pressure between 2 models was found(P=0.118),but strong consistency for the flow velocity and WSS(r s=0.730,0.807,both P<0.05).The consistencies of pressure,flow velocity and WSS between 2 models at the proximal and distal segment of stenosis,i.e.1,3—5 sampling points were week to moderate(r s=0.237—0.669,all P<0.05).Conclusion 0D-1D coupling model exhibited outstanding computational efficiency and might provide relatively reasonable results,while 3D FSI model show

目的构建先天性心脏病术后患儿中心静脉导管相关深静脉血栓(central venous catheter-associated deep venous thromboses,CADVT)风险预测模型,并验证该模型的预测效果。方法便利选取2021年1月—11月在浙江省某三级甲等儿童专科医院心脏外科监护室住院的234例患儿作为建模组,根据是否发生CADVT,将其分为CADVT组(53例)和非CADVT组(181例)。采用Logistic回归分析建立风险预测模型,采用Hosmer-Lemeshow检验判断模型的拟合优度,采用受试者操作特征曲线(receiver operator characteristic curve,ROC)检测模型的预测效果,并绘制列线图。选取2021年12月—2022年2月同一所医院收治的60例先天性心脏病术后患儿作为验证组,采用Hosmer-Lemeshow检验和ROC曲线对模型进行外部验证。结果先天性心脏病术后患儿CADVT发生率为22.65%。CVC留置时长(OR=1.172)、D-二聚体浓度(OR=1.169)、纤维蛋白原浓度(OR=3.888)、镇静天数(OR=1.538)、使用血管收缩药(OR=3.554)和儿科危重病例评分(OR=3.308)是其风险因素(P<0.05)。Hosmer-Lemeshow检验结果显示,χ^(2)=4.456,P=0.814,ROC曲线下面积为0.957(95%CI:0.930~0.984),最佳临界值为0.813,灵敏度为0.962,特异度为0.851。外部验证结果显示,该模型的灵敏度为0.857,特异度为0.870,正确率为86.67%。结论该风险预测模型的预测效果良好,可为临床评估先天性心脏病术后患儿CADVT发生风险提供参考。
