提出了一种基于无创生理参数的冠状动脉及心血管系统集总参数模型的个性化方法。系统参数由不同的生理参数决定。通过主动脉压和心率测定心脏模块；体循环模块由心输出量、身高、心踝血管指数（CAVI）决定，CAVI由年龄、主动脉压决定；冠状动脉模块由心输出量预测的冠状动脉流速目标波形确定。大量的结果证明，这种方法可以适用于每一个病人。
A method which can personalize the lumped parameter model of coronary artery and cardiovascular system based on the non-invasive physiological parameters has been developed. The parameters of system were determined by different physiological parameters. The heart module was determined by aortic pressure and heart rate; the systemic circulation module was determined by cardiac output, height and cardio-ankle vascular index (CAVI), while the CAVI was determined by age and aortic pressure; the coronary module was determined by the target waveforms of coronary flow rate predicted from cardiac output. The considerable results proved that this method could be applied to each patient.
