Abstract(in Japanese) (See Japanese page)
Abstract(in English) An optimal control theory was applied to analyze the total features of coronary circulation at systolic phase.The coronary circulation was cxprcssed by equivalent electrical circuit model composed of epicardial vessels and end cardial vesseis with intra and extra myocardial regions.Each region has resistance and capacitances.The performance function which must be minimized included the blood pressure and flow rates and their derivatives. The reconstructed pressure and intra myocardial flow curves are almost similar to physiological ones.The most influential factors are the intra myocardial distribution of resistances and initial driving pressure at near the end cardium.Present model regulated by the performance function would be available for the analysis of coronary circulation.
