Abstract
Intracellular acidosis induced by hypoxia resulted from myocardial ischemia damages myocardium. However, the detailed mechanisms of hypoxic acidosis are not quantitatively explained. The purpose of this study is to create a novel computational model which can reproduce intracellular acidosis caused by myocardial ischemia. We constructed a computational model of myocardium, by using a mathematical ventricular cell model which includes pH regulation and a computational model of myocardial microcirculation for calculating extracellular conditions. The present model reproduced cellular hypoxia in an ischemic condition simulated by a reduced blood flow, and intracellular pH reduction in response to the hypoxia.
