According to scientists from the European Respiratory and American Thoracic Society, only 25% of cases of chronic obstructive pulmonary disease (COPD) are diagnosed in time. In the remaining cases, the disease is diagnosed as a result of pulmonary hypertension (PH), followed by the development of chronic pulmonary-cardiac syndrome (CPCS). The first scientific study to assess the condition of the left ventricle (LV) in patients with COPD was conducted in the 80s and 90s, in which mainly interventional methods were used in experimental models. According to a number of recent studies, diastolic dysfunction of the heart is detected in 50-90% of patients with COPD. This article shows that cardiac hemodynamic parameters in patients with chronic obstructive pulmonary disease with pulmonary hypertension change negatively in parallel with the severity of the disease

chronic obstructive pulmonary disease (COPD), pulmonary hypertension (PPH), systolic pressure in the pulmonary artery (SPPA), left ventricul of heart (LV).
