Introduction:Physical cardiac rehabilitation is efficient in restoring patients’ adaptive capabilities. One of the goals of cardiac rehabilitation program after cardiac surgery is optimizing energy supply systems.

Methods:We examined 76 patients undergoing coronary artery bypass grafting under cardiopulmonary bypass, with a duration of 56 ± 20.5 minutes. Patients were divided into two groups: a control group (n = 38) - without bicycle ergometric training at the mean age of 54.2 ± 1.4 years, the study group at the mean age of 53.9 ± 1.3 years (p> 0.05) (n = 38), undergoing cardiac rehab training program. In both groups, cardiorespiratory test was initially conducted. Aerobic exercises were carried out on exercise bikes SCHILLER 14 days after CABG. The load power was from 25 to 70-90 W. Following energy supply parameters were estimated before and after cardiac rehab: lactate, glucose, lipid profile, pH, PCO2, pO2, BE blood along with parameters of external respiration, heart rate and blood pressure.

Results:At the end of the course of cardiac rehabilitation, were revealed significant decrease in systolic blood pressure 155 ± 5.7 mm Hg. (р <0.05), the increase of peak oxygen consumption VO2peak 20.0 ± 0.9 ml / kg / min (p <0.05), blood lactate reduction 1.7 ± 0.2 mmol / l (p <0.05), decrease in lipid profile, increase of exercise tolerance 6,3±0,1 METS.

Conclusions:Obtained results showed that the course of the rehabilitation after heart surgery in the second stage of rehabilitation could optimize patients’ aerobic productivity and exercise tolerance.
