Instantaneous wave-free ratio (iFR) has been proposed as a hemodynamic parameter that can reliably reflect the blood flow in stenosed coronary arteries. Currently, there are few investigations on the quantitative analysis of iFR in the patients regarding the variation of microcirculatory resistance (MR). The data aim to provide geometric (cross-section area of branches) and hemodynamic (flow rate and iFR of branches) parameters of normal and stenosed coronary arteries derived from CFD simulation. The CFD simulation was performed on the three-dimensional artery models reconstructed from computed tomography (CT) images of four subjects. The hemodynamic parameters were obtained in six situations of MR to simulate coronary microvascular dysfunction (CMD). This dataset could be used as the reference to estimate the iFR and flow rate in patients with CMD and stenosis in coronary arteries. The geometric parameters could be used in the modelling of coronary arteries.
瞬时无波比值（iFR）已被提出作为一种血流动力学参数，它能够可靠地反映狭窄冠状动脉中的血流情况。目前，关于微循环阻力（MR）变化对患者iFR定量分析的研究较少。这些数据旨在提供通过计算流体动力学（CFD）模拟得出的正常和狭窄冠状动脉的几何参数（分支横截面积）和血流动力学参数（分支流速和iFR）。CFD模拟是在从四名受试者的计算机断层扫描（CT）图像重建的三维动脉模型上进行的。在六种MR情况下获取血流动力学参数，以模拟冠状动脉微血管功能障碍（CMD）。该数据集可作为估算患有CMD和冠状动脉狭窄患者的iFR和流速的参考。几何参数可用于冠状动脉建模。
