摘要

建立了一个模型来研究局部左室力学、局部冠状动脉血流和一些重要的潜在代谢因素之间的时变关系。作者先前的左室模型被扩展到模拟局部冠状动脉血流改变所施加的心脏局部行为的变化。这是通过量化区域心脏代谢和功能之间的关系来实现的。该模型能够预测冠状动脉狭窄后心肌缺血发展过程中心功能的急性变化。

A computer simulation of the dynamic interaction between regional coronary flow and LV mechanics

A model was developed to study the time-varying relation between regional LV mechanics, local coronary flow and some of the important underlying metabolic factors. The authors' previous LV model was extended to simulate the changes in regional behavior of the heart imposed by modifications in local coronary flow. This was accomplished by quantifying the relation between regional heart metabolism and function. The resulting model is capable of predicting the acute changes in heart function during the development of myocardial ischemia following coronary stenosis.<>
