Myocardial Oxygen Supply and Demand

摘要: The supply of oxygen to the myocardium is determined by coronary blood flow and carrying capacity. Coronary a dynamic process modulated via multiple parameters. Cardiac metabolism also affected several factors. Under normal physiologic conditions, demand easily met oxygen. In fact, there significant reserve on side. certain pathologic states such as artery disease, may be exhausted an imbalance between occurs which translated into ischemia. area most susceptible ischemia subendocardium due mechanical metabolic forces. therapy attention should directed directional changes in factors influencing improve area.
