The functional capacity of mammary-coronary bypass was assessed in acute dog experiments by means of electromagnetic flow measurement and estimation of myocardial flow by hydrogen polarography. 1)In the intact myocardium the central flow of the mammary-coronary bypass and the tissue perfusion provided by its correspondence to the functional capacity of the intact anterior descending coronary; 2) despite an unchanged perfusion pressure the myocardium damaged by infarction is no longer able to take up the available quantity of blood, and both flow and tissue perfusion decrease; 3) the reactive hyperaemia induced by ischaemia considerably reduces the microcirculation of the damaged myocardial tissue.
在急性犬实验中，通过电磁流量测量和用氢极谱法估算心肌血流量，对乳内动脉 - 冠状动脉搭桥的功能能力进行了评估。1）在完整心肌中，乳内动脉 - 冠状动脉搭桥的中心血流量及其与完整前降支冠状动脉功能能力相对应所提供的组织灌注；2）尽管灌注压力不变，但梗死损伤的心肌不再能够摄取可用的血量，血流量和组织灌注均降低；3）缺血诱导的反应性充血显著减少了受损心肌组织的微循环。
