Regional myocardial blood flow (MBF) and left ventricular (LV) function were measured in 18 dogs after 60 min hypothermic (14-16 degrees C) arrest with (group I) and without cardioplegia (group II). Regardless whether postischemic LV function was severely (group II) or only moderately (group I) impaired, the amount of MBF and its transmural distribution was not significantly altered after 30 min reperfusion. In contrast to topical hypothermia, additional cardioplegia maintained metabolic regulation of coronary flow.
在18只犬中，分别于低温（14 - 16摄氏度）停搏60分钟且使用心脏停搏液（I组）和不使用心脏停搏液（II组）后，测量局部心肌血流量（MBF）和左心室（LV）功能。无论缺血后左心室功能是严重受损（II组）还是仅中度受损（I组），再灌注30分钟后，MBF的量及其透壁分布均无显著改变。与局部低温相反，额外使用心脏停搏液可维持冠状动脉血流的代谢调节。
