Dilated cardiomyopathy was observed in 2 patients with chronic obstructive lung disease. This association raises first a diagnostic problem: the low specificity of clinical, radiographic and electrocardiographic signs makes it difficult to diagnose a left ventricular failure in such patients. Echocardiography is useful, but right and left heart catheterization and coronary arteriography are needed to establish the diagnosis of dilated cardiomyopathy and exclude other causes of left cardiac failure. The cause-effect relationship between the 2 diseases is not easy to evaluate. It is studied here in the light of the different mechanisms suggested to explain the repercussions function and notably the interactions between ventilation and right and left ventricular function. However, the association of the 2 diseases seems to be fortuitous. Their reciprocal repercussions, notably in the field of haemodynamics, are unquestionable and make the overall prognosis worse.
在2例慢性阻塞性肺疾病患者中观察到扩张型心肌病。这种关联首先引发了一个诊断问题：临床、影像学和心电图体征的低特异性使得在此类患者中诊断左心室衰竭变得困难。超声心动图是有用的，但需要进行右心和左心导管检查以及冠状动脉造影来确诊扩张型心肌病并排除左心衰竭的其他原因。这两种疾病之间的因果关系不易评估。本文根据为解释其功能影响，尤其是通气与右心室和左心室功能之间的相互作用而提出的不同机制对此进行了研究。然而，这两种疾病的关联似乎是偶然的。它们的相互影响，尤其是在血流动力学领域，是毋庸置疑的，并且会使总体预后更差。
