A study was carried out on 59 patients with significant stenosis (greater than or equal to 75%) in at least one coronary vessel. For each parietal region of the left ventricle the pattern of contraction was defined through a study of the regional deformation as vectorial time-dependent parameter and of the construction of the pressure-length loops. The different models obtained in basal conditions and through intervention (nitroglycerin and post-extrasystolic potentiation) were correlated with experimental data on ischemic alterations of the regional mechanical performance.
对59例至少有一支冠状动脉存在严重狭窄（大于或等于75%）的患者进行了一项研究。对于左心室的每个壁区域，通过将区域变形作为随时间变化的矢量参数进行研究以及构建压力-长度环来定义收缩模式。在基础状态下以及通过干预（硝酸甘油和早搏后增强）获得的不同模型与关于区域机械性能缺血性改变的实验数据相关。
