Background: To give a comparative evaluation of the parameters of exercise test (ET) in conjunction with the heart rate variability (HRV) in patients with CAD, with CHD and AH and only AH. Methods: 80 pts were included in the study, which was 51,76 ± 9,65 years (range 25 to 73 years), of which 49 (61.25%) - males. All patients were examined: the calculation of body mass index (BMI), the HRV parameters. Results: The pts of 2gr. characterized by relatively high values of body weight = 82,45 ± 10,15 kg, 3.07% and 7.57% more than 1gr. and 3gr. (BMI in 1gr. = 28,80 ± 3,95 kg/m2; in 2gr. = 29,83 ± 3,25 kg/m2; in 3gr. = 27,51 ± 3,89 kg/m2). HRV parameters confi rmed the results, SDNN, rMSSD, pNN50 and TI had the lowest values in patients 3gr. Spectral indices point to the prevalence of low-frequency spectrum of HRV (LF / HF = 4,47 ± 2,97, which is 1.4 and 1.7 times higher than in groups 1 and 2, p <0.05. However, analysis of exercise capacity revealed that patients of 3gr. had high exercise capacity at 37.5%, against 33.3% and 15%, respectively, 1 and 2 groups, with an average exercise capacity - 50% vs. 58% and 80%, respectively, in groups 1 and 2, and low exercise capacity - in 12.5% versus 8.3% and 5%, respectively, in groups 1 and 2 (all p> 0.05). Conclusions: Patients with AH during the exercise test, despite of a relatively high tolerance to physical activity and relatively low weights, characterized by autonomic imbalance with a predominance of sympathetic activity of the autonomic nervous system.

Background: To compare clinical and functional patients with isolated right heart dilatation (RVDC) depending on the presence or absence of pulmonary hypertension (PH). Methods: We examined 22 patients who had DC with a primary lesion of the right heart (17 - females, 5 - males). All performed: blood examination, ECG, echocardiography with determination of ejection fraction (EF) of the right ventricle (RV) and the mean pulmonary artery pressure (MPAP), 6-minute walk test (6MWT) and external respiration parameters. Results: According to general clinical laboratory data analyzed differences in the groups have been identified. Noted a relative increase in the level of Hb levels in pts of 1gr., amounting to 135,7 ± 14,6 g / l vs 2gr. = 120,2 ± 23,7 g / l (p> 0.05). Data of 6MWT showed 201,8 ± 86,1 m in 1gr. vs 163,2 ± 60,4 m in 2 gr. respectively. Nevertheless, according to spirometry patients with PH have lower VC (1gr.= 63 5 ± 16,5 l and 2gr. = 67,7 ± 6,3 l), all p> 0.05. The echocardiography parameters of 1gr. : EDV = 90,5 ± 41,6 ml, ESV = 27,5 ± 12,6 ml, that on 26.8% and 29.1%, respectively, were more of similar indicators of 2 gr, with LVEF in 1gr. = 68,9 ± 6,3% and in 2gr. = 69,6 ± 9,6% (all p> 0.05).RV of 1 gr.=55,2±9,7 and RV of 2 gr.=51,3±7,3. RA of 1 gr.=56,7±15,7 RA of 2 gr. = 47,8 ± 9,4; RV EF in 1gr. = 35,7 ± 8,2 that on 9.2% was lower than in 2gr. Conclusions: Patients with RVDC and the presence of LH characterized by elevated levels of Hb, lower VC and RVEF despite of more good parameters of 6MWT.
