《英国医学杂志》第2卷第6199期(1979年11月10日)第1167页报道:临床上辨认冠心病是基于冠状动脉发生固定的器质性梗塞,复因运动缺氧,而诱发心绞痛。由于心肌需用冠状动脉血中75％以上的氧,因此,心肌依赖于因血流变化而引起的氧供应的变化。在健全的心脏,血流随着冠状动脉阻力的减低而增加;但是,如冠状动脉支发生固定的 “British Medical Journal” Volume 2 No. 6199 (November 10, 1979) No. 1167 reported that: clinical identification of coronary heart disease is based on the fixed occlusion of the coronary artery occlusion, complex exercise hypoxia, and induced angina . Because of the myocardial need for more than 75% of the oxygen in coronary blood, the myocardium relies on changes in oxygen supply due to changes in blood flow. In a healthy heart, blood flow increases with decreased resistance to coronary arteries; however, as is the case with fixed coronary arteries
