Abstract
Objective: to assess pulmonary hemodynamics and the presence of systolic and/or diastolic dysfunction of the myocardium of the right and left ventricle in patients with COPD, depending on the risk groups A, B, C, D. Materials and Methods: Patients (n = 122; 89 were men, mean age - 62.8 ± 15,2 years) with COPD of risk group A (n=23) and B (n=99) (GOLD, 2019). In addition to conventional clinical and instrumental examinations, pulmonary and aortic pulse wave velocity were determined using MRI diagnostics. Results: Disorders in the form of right ventricular diastolic dysfunction (DD) were revealed in all patients with COPD (E/A TV = 0.86±0.04 vs 0.96±0.02; groups A and B respectively, p Conclusion: Thus, patients with COPD risk group A are defined the edge indicators of mPAP with the development of DD of LV and RV. The progression of hemodynamic disorders is associated with the weighting of clinical manifestations and respiratory disorders, more pronounced in patients of group B, which requires mandatory broncholytic drug correction.
