Malperfusion due to increased coronary vascular resistance is presumably one of the factors responsible for incomplete functional recovery of the heart after aortic cross-clamping. Myocaridal blood flow (MBF, radioactive microspheres) was measured before and after 60 min of hypothermic ischemia in 16 dogs on cardiopulmonary bypass. After ischemia the hearts were reperfused for 30 min. MBF was measured in the empty beating heart and in the isovolumetrically contracting ventricle loaded with enddiastolic volumes (EDV) of 10, 20 and 30 ml (intraventricular latex balloon).
由于冠状动脉血管阻力增加导致的灌注不良可能是主动脉交叉钳夹后心脏功能恢复不完全的原因之一。在16只接受体外循环的犬中，于低温缺血60分钟前后测量心肌血流量（MBF，放射性微球法）。缺血后心脏再灌注30分钟。在空跳心脏以及充盈舒张末期容积（EDV）分别为10、20和30毫升（心室内乳胶球囊）的等容收缩心室中测量MBF。
