Left ventricular remodelling plays an important pathogenetic role in progressive circulatory insufficiency both in dilated cardiomyopathy (DCMP) and in ischemic heart disease with postinfarction cardiosclerosis. In terminal cardiac failure structural changes (changed geometry of the left ventricle, in particular) become stereotypic. The dobutamin test in DCMP reveals low functional reserve of the total and segmentary contractility compared to ischemic cardiomyopathy. This may help in echocardiographic diagnostic difficulties.
左心室重构在扩张型心肌病（DCMP）和心肌梗死后心肌硬化的缺血性心脏病所致的进行性循环功能不全中均起着重要的致病作用。在终末期心力衰竭中，结构改变（尤其是左心室几何形状改变）变得刻板。与缺血性心肌病相比，DCMP中的多巴酚丁胺试验显示整体和节段性收缩功能储备较低。这可能有助于解决超声心动图诊断难题。
