Abstract
Introduction. The reduction in the risk of repeated hospitalizations was revealed against the background of ongoing cardiac rehabilitation after coronary artery bypass grafting (CABG). A number of studies have revealed a reduction in the risk of repeated hospitalizations on the background of ongoing cardiac rehabilitation after CABG. Physical cardiorehabilitation is an effective means of restoring the adaptive capabilities of the organism. The goal of the cardiorehabilitation training program after cardiac surgery is optimization of energy supply systems.
Objective: to study the effectiveness of the optimal сardiac rehabilitation program for the lactate system in cardiac patients.
Material and methods.We examined 36 patients undergoing coronary artery bypass grafting under conditions of artificial circulation, with an IR duration of 56±20.5 minutes, were divided into two groups: a control group (n=15) without performing bicycle ergometric, the age of 54.2±1.4 years, the main group (n=21) – with the exercise of the bicycle ergometric load at the age of 53.9±1.3 years (p>0.05). Of these, 22 (61.1%) men, 14 (38.9%) women. Gender was not considered. Anaerobic exercise carried out on exercise bikes Schiller 10 days after CABG. The load power was from 25 to 70–90 W. Before cardiorehabilitation estimated lactate, glucose, pH, PCO2, pO2, BE blood before and after the load ergometric data of external respiration, heart rate and blood pressure. After the rehabilitation course, the above parameters were evaluated.
Results. When assessing the indices in the basis of the group at the end of the course of cardiac rehabilitation, a significant decrease in systolic blood pressure after exercise is 155±5.7 mm Hg (p<0.05), an increase in the value of VO2peak to 19.0±0.9 ml/kg/min (p<0.05), lactate in the blood decreased to 1.7±0.2 mmol/l (p<0.05). There were no significant changes in pH, blood glucose, or heart rate.
Conclusions. Analysis of the results showed that a properly fitted load ergometric parameters can optimize
the anaerobic glycolysis in patients undergoing surgery with cardiopulmonary bypass, as well as increase the
functionality of patients.
