心脏生理组项目的一个主要目标是开发理论模型,以模拟心脏在生理和病理生理条件下的功能行为。心脏功能严重依赖于通过冠状动脉血管系统向心肌输送充足的血液供应。冠状动脉血管系统这一关键功能的关键是系统动力学,系统动力学是通过在一定范围的空间和时间尺度上的众多组成成分的相互作用而出现的。在这里,我们专注于几个组件,理论方法可以应用,包括血管结构和力学,血流和质量运输,流量调节,血管生成和血管重塑,血管细胞力学。对于每个组件,我们总结了模型开发的当前状态,并讨论了需要进一步研究的领域。我们强调的主要挑战与集成组件模型开发的计算工具,最终可用于模拟冠状动脉血管系统的反应不断变化的需求和疾病和治疗。
A key aim of the cardiac Physiome Project is to develop theoretical models to simulate the functional behaviour of the heart under physiological and pathophysiological conditions. Heart function is critically dependent on the delivery of an adequate blood supply to the myocardium via the coronary vasculature. Key to this critical function of the coronary vasculature is system dynamics that emerge via the interactions of the numerous constituent components at a range of spatial and temporal scales. Here, we focus on several components for which theoretical approaches can be applied, including vascular structure and mechanics, blood flow and mass transport, flow regulation, angiogenesis and vascular remodelling, and vascular cellular mechanics. For each component, we summarise the current state of the art in model development, and discuss areas requiring further research. We highlight the major challenges associated with integrating the component models to develop a computational tool that can ultimately be used to simulate the responses of the coronary vascular system to changing demands and to diseases and therapies.
