The aim of the work: to assess the effectiveness of early postoperative rehabilitation measures in patients who underwent myocardial revascularization and surgical correction of aortic aneurysms.
Materials and Methods. A single-center retrospective cohort study included 227 patients, whose age range was 41–82 years (mean age (62.6±8.6) years). All patients in the study underwent myocardial revascularization by performing aortocoronary bypass and surgical correction of aortic aneurysms (dissection of the ascending aorta, arch or descending part). The study patients were assessed for: functional status based on the ability to perform daily physical activities and cardiovascular risk by conducting a survey using the Duke Activity Status Index. In order to assess the characteristics of early rehabilitation, gradual submaximal stress testing on a cycle ergometer was performed with symptom limitation to assess the level of physical fitness and determine the optimal intensity of further training. The exercise protocol was individually selected according to the patient's clinical condition.
Results. As a result of the study, a significant improvement in exercise tolerance was observed, which was manifested in an increase in power during bicycle ergometric training by an average of (19.6±10.2) W. After completing the early rehabilitation course, all patients in the study showed a statistically significant improvement in functional status (p=0.05). The DASI index increased by 13.1 %, walking speed and distance of tests with 2- and 6-minute walk by 15.6–19.2 % (p=0.05). The indicators of external respiratory function significantly improved, namely: vital capacity of the lungs and its relative value by 13.0 %, peak expiratory flow by 20.5 % (p=0.05).
Conclusions. It was established that early physical rehabilitation, which began on the 3rd–7th day after surgery, and the active phase on average began on the 21st day, is safe and effective in patients after coronary artery bypass grafting and correction of aortic pathology. It was found that when observing the protocol for monitoring hemodynamic indicators, complications and adverse reactions did not occur. Thus, the use of a standardized 7-day protocol provided a significant increase in tolerance to physical exertion, the key markers of endurance were: the 6-minute walk distance, which increased by 19.2 % (p=0.05) and the estimated household activity according to the DASI index, which increased by 13.1 % (p=0.05).
