Methods: the model of acute myocardial ischemia in rats was developed by ligaturing the left descending anteriorcoronaryartery.
方法：采用结扎大鼠冠状动脉左前降支复制出大鼠心肌缺血再灌注损伤模型。

Objective: Color Doppler ultrasonography (CDU) study internal mammary artery (IMA) dynamic changes for left anteriorcoronaryartery bypass graft operation.
目的：研究冠状动脉搭桥术前后乳内动脉(IMA)血流动力学的改变，为临床提供安全可靠的检查方法。

Dynamic compression occurred almost exclusively (97.5% of the time) in patients with full encasement of the left anterior descending coronaryartery, regardless of the presence of overlying muscle.
