Conclusions

Whereas under experimental conditions it is possible to investigate the responses of the self-regulatory mechanisms of the coronary circulation either with a constant load on the myocardium and variable conditions of perfusion of the coronary system [17] or vice-versa [18], in the case of balloon pulsation both these factors act togetherandin animal experiments cannot be distinguished. At the same time, their separate evaluation is important in studying the hemodynamic efficiency of the counterpulsation method. The proposed model of the biomechanics of the coronary circulation is sensitive to changes in the conditions of perfusion of the myocardium and at the same time maintains a constant value of the coronary resistance irrespective of the energy consumption of the heart. Accordingly, by comparing the results of modeling and the experimental data it is possible to estimate the contribution of the self-regulatory mechanisms of the coronary blood flow to the change in the transport functions of the coronary circulation associated with intraaortic balloon pulsation.

Thus, the proposed model can be used as a tool for investigating the blood supply to the normal heart and for the partial evaluation of the hemodynamic efficiency of the intraaortic counterpulsation method.
