Hemodynamic effects of perfusion level of peripheral ECMO on cardiovascular system.

abstract：BACKGROUND:A computational model of myocardial energy metabolism was used to assess the metabolic responses to normal and reduced myocardial blood flow. The goal was to examine to what extent glycolysis and lactate formation are controlled by the supply of glycolytic substrate and/or the cellular redox (NADH/NAD+) and ...
