正常时,心脏的收缩能量大部分来源于游离的脂肪酸,然而,缺血的心肌能量的来源则主要靠葡萄糖的无氧酵解作用。胰岛素的主要功用是保证葡萄糖的输送和利用。因此,当心力衰竭时,胰岛素的分泌受到抑制,常导致心肌机能的进一步破坏。为了说明葡萄糖、胰岛素和氯化钾治疗冠心病心衰的临床价值,作者进行了如下实验研究。 Normally, most of the energy of the heart is derived from free fatty acids, however, the source of ischemic myocardial energy is mainly glucose anaerobic glycolysis. The main function of insulin is to ensure the delivery and utilization of glucose. Therefore, when heart failure, insulin secretion is inhibited, often leading to further damage to myocardial function. To illustrate the clinical value of glucose, insulin, and potassium chloride in the treatment of CHD, the authors conducted the following experimental studies.
