冠状动脉狭窄或闭塞导致心肌缺血，影响心脏功能。心脏功能的预后有诸多因素的参与，其中重要因素之一是冠状动脉侧支循环的建立与否及其发达程度。侧支循环的存在可防御或减少心肌缺血或坏死。以往对冠状动脉侧支循环的研究着重于血管内压及血流等物理因素。近年来，血管内皮?
Coronary stenosis or occlusion leads to myocardial ischemia, affecting heart function. The prognosis of cardiac function has many factors involved, one of the important factors is the establishment of coronary collateral circulation and its development. The presence of collateral circulation can prevent or reduce myocardial ischemia or necrosis. Previous studies of coronary collateral circulation have focused on physical factors such as intravascular pressure and blood flow. In recent years, vascular endothelial?
