心肌是需氧性组织,也是体内耗氧量较大的器官之一。骨骼肌则不同,即在紧急需要能量时可相对成为不需氧性组织。所以,心肌与骨骼肌尽管在代谢途径上“大同小异”,但各有特点。随着基础理论研究的进展,人们逐渐认识到心肌代谢的障碍是心肌病的原发性机制,而血液动力学的变化,只是其障碍的后果。因此,阐明心肌代谢,对理解心血管疾病的机制,可提供重要的理论基础。篇幅所限,本文仅重点介绍心肌代谢特性、心肌代谢调
Myocardium is aerobic tissue, but also one of the organs of larger oxygen consumption in the body. Skeletal muscle is different, that is, in the event of an urgent need for energy can be relatively non-oxygenated tissue. Therefore, although myocardial and skeletal muscle in the metabolic pathways are “similar”, but each has its own characteristics. With the progress of basic theoretical research, people gradually come to realize that the obstacle of myocardial metabolism is the primary mechanism of cardiomyopathy, and the change of hemodynamics is only the consequence of its disorder. Therefore, clarifying myocardial metabolism may provide an important theoretical basis for understanding the mechanism of cardiovascular diseases. Space limitations, this article focuses only on myocardial metabolic properties, myocardial metabolism tone
