Objective: To study the performance of intracardiac hemodynamics in patients with arterial hypertension (AH) and chronic obstructive pulmonary disease (COPD).
Materials and methods. The study included 21 patients , divided into two groups. The first group included 13 patients with a combination of hypertension and COPD (8 males and 5 females, mean age 62,03 ± 1,85 years), in the second group  - 10 people (6 men and 4 women, mean age 54,87 ± 3 , 05 years) with hypertension without COPD. All the patients underwent an echo-cardioscopy.
Results. The study showed that the value of end-diastolic dimension (EDD) of the left ventricle (LV) in patients with hypertension and COPD was significantly less  than in group 2. In patients with a combination of hypertension and COPD compared with those with hypertension without COPD had significant reduction in end-diastolic volume (EDV) of LV (98,85 ± 3,21 and 125,50 ± 2,12 ml, respectively). Lower values of minute volumes (MV), cardiac (CV) volumes and ejection fraction (EF) were determined in patients with hypertension and COPD compared with the same parameters in patients with hypertension without COPD. Elevated systolic pulmonary artery pressure (SPAP) in patients with COPD in the presence of hypertension.
Conclusions. Thus, more complex hemodynamic conditions for the functioning of the heart in comorbidity lead to much more severe hemodynamic disturbances of right ventricular and the pulmonary circulation and accelerate the development of the chronic pulmonary heart.
