Introduction: In recent years, COPD is observed as not an isolated, but an associated pathology, in particular, concurrent with metabolic syndrome. The aim of the research is to identify the differences in changes of the rheopulmonography parameters (RPG) depending on the presence of hypertrophy or atrophy of the right ventricular myocardium in patients with COPD concurrent with metabolic syndrome.. Materials and methods: We studied changes in rheopulmonography (RPG) in 145 patients with chronic obstructive pulmonary disease (COPD) concurrent with metabolic syndrome. Results: We detected precapillary hypertension of the pulmonary circulation in patients with right ventricular myocardial hypertrophy: anacrotism serration; flattened peak of the systolic wave; decreased Vcp; high placement of incisura; horizontal course of catacrotism; decreased amplitude of the systolic wave (in this case, due to a greater increase in the resistance of the blood flow in the pulmonary vessels than the decreased impact volume of the right ventricle); prolonged Q-a (in this group of patients, it depends more on hypertension of the pulmonary circulation than on the reduction of contractile function of the myocardium). In atrophy of the right ventricular myocardium, the following changes in the RPG were revealed: decreased systolic wave at its dramatic rise; prolonged Q-a (in this case, due to the weakened heart contraction); Vmax reduction (it reflects the reduction of myocardial contractility); in hypertrophy of the myocardium, Vcp., unlike RPG, does not decrease, which is explained by the decrease in the pressure of the pulmonary circulation. Conclusions: We believe that these changes in RPG allow differentiating hypertrophy and right ventricular myocardial atrophy along with established diagnostic criteria, and can be used as markers for the diagnosis and treatment of COPD concurrent with metabolic syndrome.

Chronic obstructive pulmonary disease (COPD) characterized by interminable air flow limitation that is not fully reversible COPD includes chronic bronchitis, emphysema, and chronic asthmatic bronchitis.  Chronic obstructive pulmonary disease as a complex disease with various systemic manifestations and one of the co-morbidity linked with COPD is cardiovascular disease.  Hypoxic vasoconstriction and alterations in pulmonary microvasculature, which are both observed in COPD patients, leads to an increase in pulmonary vascular resistance. As a result, this increase in right ventricular (RV) after load causes right ventricular remodeling, including chamber dilatation and wall hypertrophy and ultimately to functional deterioration.  The aim of this study to evaluate the right ventricular changes that develop secondary to COPD using GOLD guidelines and echocardiographic findings .This cross-sectional study involved 134 patients who presented to the pulmonary disease outpatient clinic with COPD. We assessed the right ventricular changes in COPD patients of different severity using echocardiography .COPD patients shown change in the right ventricular dimensions as the severity of COPD increases and right ventricular function as well.  It is also observed that frequency of pulmonary hypertension also increased as the severity of COPD increases. The study shows high prevalence of cardiac co-morbidities such as RV dysfunction and pulmonary hypertension in COPD patients. The severity of complications increases with severity of COPD and makes a linear relation. Keywords: Echocardiography, ECG, COPD
