Myocardial blood flow and ventricular function was studied in seven dogs with chronic myocardial ischemia before and after coronary bypass grafting. Restoring blood flow in an area of 25% of the anterior wall of the left ventricle did not significantly improve overall ventricular function. Assessment of intramyocardial pressure as an index of regional myocardial function revealed a consistent enhancement of myocardial contraction at rest, and under pharmacological stress of the heart.
在七只患有慢性心肌缺血的犬身上，于冠状动脉搭桥术前和术后研究了心肌血流和心室功能。恢复左心室前壁25%区域的血流并未显著改善整体心室功能。将心肌内压力作为局部心肌功能指标进行评估发现，在静息状态以及心脏受到药理学应激时，心肌收缩均持续增强。
