[0003]
[0004] Normal myocardial energy (ATP) supply 60% to 70% from free fatty acid β oxidation, 20% to 25% from glucose oxidation, 5% to 10% from glycolysis. The oxygen consumption of free fatty acid oxidation to produce the same amount of ATP is higher than that of glucose oxidation, and high levels of free fatty acid oxidation can significantly inhibit the rate of glucose oxidation. During myocardial ischemia, the sympathetic nerve is excited, and the level of catecholamines increases, which in turn leads to an increase in the level of free fatty acids in the blood; the oxidation of free fatty...
