[Structural and functional changes in myocardium at rest and under exertional test in dust bronchitis patients having coronary heart disease and arterial hypertension].

The estimation of structural-functional state of right and left heart before and after loading test at patients suffered from chronic mechanic bronchitis in combination with ischemic heart disease and arterial hypertension is carried out using an echocardiography method. It is revealed that the combination of chronic mechanic bronchitis, ischemic heart disease and arterial hypertension results in remodelling both ventricles and hastens chronic pulmonary heart development.
