Impact of spiral orientation of myofibres and ventricular syncitium: study of left ventricular dysfunction in 22 patients of copd with cor-pulmonale with normal coronary arteries.

ABSTRACT

Clinical presentation of breathlessness on exertion is often confused between angina equivalent - breathlessness and pulmonary origin breathlessness. echocardiographyand Dop-pler evaluation has been used for differentiating these aetiologies in an individual. However, at times even echocardiography is not informative as it brings out biventricular dysfunction and hence LV dysfunction can not be ruled out in COPD, cor-pulmonale patients on clinical grounds alone. Established cases of COPD, cor-pulmonale may have. significant LV dysfunction also. The possible explanation of this biventricular dysfunction is anatomical. These patients have LVD without IHD. EGG evidence and angiographic evidence of IHD is lacking though LV dysfunction is present. The observational study tries to evaluate left ventricular function in COPD, cor-pulmonale patients
