X-ray methods of examination: a survey X-ray; polypositional large-scale fluorography of the chest organs, including in the polar phases of respiration; electron roentgenography (ERTG), computed tomography (CT).

Comprehensive ultrasound of the heart was performed on Shimadzu SDU 500 A and Aloka 650SSD (Japan) devices in M-, B- and Doppler modes, using 3.5 MHz sensors, from the parasternal and apical approaches. by standard methods, with the definition of parameters of pulmonary and hemodynamic valuable tral: end-diastolic dimension of the right ventricle (KDR RV ), the front wall thickness of the myocardium of the right ventricle (RV) in diastole (TMPS RV ), end-diastolic volume of the prostate (BWW RV ), end-systolic volume of the prostate (CSR RV ) ary RV index (MI RV ), cardiac index RV (SI RV ) RV ejection fraction tion (EF RV ), the final systolic size of the left ventricle (LV) ( LV LCR ), the final diastolic LV size ( LV CRD ), the myocardium thickness of the LV posterior wall in the diastole (TMVF LV ), of course, the diastolic LV volume ( LV LV ), the finite systolic volume LV (CSR LV ), the minute volume of blood circulation ( LV LV ), the LV stroke volume ( LV LV ), the LV LV index ( LV LV ), the LV cardiac index ( LV LV ), the LV ejection fraction ( LV LV ), interventricular thickness partitions in diastole (TMZHP D ) [45, 46, 11 9, 273, 345]. The mean pressure in the pulmonary artery (SrDLA) was calculated using the formula A. Kitabatakae et. al. The normal value of the SrDLA index was 9–16 mm. Hg Art., pulmonary hypertension was discussed when SrDLA increased at rest more than 20 mm. Hg Art. [9, 10]. Evaluation of the diastolic function of the myocardium of the right and left ventricles was carried out by analyzing the spectrum of the transtrikuspidal and transmitral Doppler streams. The maximum blood flow velocity during the early (fast) diastolic filling of the right ventricle (E TC ), the maximum blood flow velocity during atrial systole during the late diastolic filling of the right ventricle (A TC ), the maximum blood flow velocity during the early (fast) diastolic filling of the left ventricle (E MK ), maximum blood flow velocity during atrial systole in the late diastolic filling phase of the left ventricle (A MK ), E / A RV and E / A LV ratio.
