Regional wall motion of the left ventricle (LV) has been analyzed from contrast ventriculograms by using 4 methods based on different geometrical frameworks. Two of them utilize moving internal reference systems, the center of mass (CMM) and the long axis (LAM) methods; the two other ones use fixed external reference systems, the area-based (ABM) and the Palo Alto (PAM) methods. The techniques were applied on a set of 81 patients: 42 were normal and composed the group I; 22 had a single vessel obstruction greater than 75% of the left anterior descending coronary artery (group II) with old necrosis or active ischemia of the LV anterior wall; 17 had a single vessel obstruction greater than 75% of the right coronary artery (group III) with old necrosis or active ischemia of the LV inferior wall. ABM and PAM showed the highest specificities and sensitivities on the studied sample. Therefore, we believe these two methods, of the techniques tested, are the best to quantitate wall motion from cineangiograms.
已采用基于不同几何框架的4种方法，从对比心室造影分析左心室（LV）的区域壁运动。其中两种方法利用移动内部参考系统，即质心（CMM）法和长轴（LAM）法；另外两种方法使用固定外部参考系统，即基于面积（ABM）法和帕洛阿尔托（PAM）法。这些技术应用于一组81例患者：42例正常，组成I组；22例左前降支冠状动脉阻塞大于75%（II组），伴有左心室前壁陈旧性坏死或活动性缺血；17例右冠状动脉阻塞大于75%（III组），伴有左心室下壁陈旧性坏死或活动性缺血。ABM和PAM在所研究样本中显示出最高的特异性和敏感性。因此，我们认为在所测试的技术中，这两种方法是从电影血管造影定量壁运动的最佳方法。
