Introduction: In world practice, the selection intensity physical training of patients with CHF on the basis of achievement of anaerobic threshold when you perform cardiorespiratory test (CPET). The majority of patients with severe HF do not reach anaerobic threshold during the CPET that requires the use of certain indicators in the appointment of physical training. This alternative indicator can be lactate threshold, which achieved first during the execution of the CPET. Purpose: To evaluate the effectiveness of aerobic physical exercise in HF patients, selected on the basis of determining the lactate threshold during CPET. Methods. 56 patients, CHF NYHA III (under the supervision of cardiologists-experts in heart failure) were randomized into two groups - primary (aerobic training) and control (standard treatment of heart failure). Main group - 43 patients, mean age 54 ± 12.5 years, body mass index (BMI) 26,46 ± 6.4 kg/m2. The control group - 13 patients, age 53 ± 17 years, BMI was 25.4 ± 6.8 kg/m2. The original estimated results of physical examination, laboratory parameters. CPET, quality of life (QOL), exercise tolerance (ET) was assessed at baseline and after 1,3,6 months of follow-up. The CPET served on tredmile using hardware "O×ycon ro". Echocardiography (EchoCG) were performed at baseline and after 6 months. The data were statistically processed using software package "Statistika, 6.0". Results: In the main group after 6 months of training EF increased by 7.5 ± 0.5% from baseline, QOL was changed by 17.5 ± 8 points (significant regression of symptoms). ET increased by 9 ± 1 points. After 1 month of observation VO2 peak increased by 2.6 ± 0.1 ml/min/kg after 6 months – 4.4 ml/min/kg In the control group showed an increase EF 4 ± 1,1%, the change of QOL 14 ± 7,22 points, the increase in ET at 1.5 points. Decreased VO2 peak in a month 1.05 ± 1.2 ml/min/kg, after 6 months - 1.7 ml/min/kg. Revealed a strong positive correlation between the initial values of VO2 peak and EF (rEF=0,4, p), and between baseline levels of sodium, hemoglobin and the effectiveness of physical rehabilitation (rNa = 0,41, p,0,05; rHb = 0,45, p<0,05). Conclusion: Aerobic physical exercise in CHF patients, selected on the basis of achieving lactate threshold during the CPET effective in improving values of CPET, EchoCG, QOL and increasing ET.
