Effects of Early Cardiac Rehabilitation Training on Cardiac Function and Quality of Life in Elderly Patients Undergoing Coronary Artery Bypass Grafting: A Retrospective Study

Objective: This study aimed to explore the effect of early cardiac recovery training on the cardiac function and life quality of elderly patients undergoing coronary artery bypass grafting (CABG). Methods: Elderly patients who underwent CABG in our hospital from January 2022 to November 2023 were selected as the subjects, and their clinical data were retrospectively analyzed. In accordance with the different rehabilitation intervention methods of the patients, they were separated into control group (C group) and research group (R group). The C group received conventional rehabilitation intervention, and the R Group received early cardiac recovery training intervention. The cardiac function indices and quality of life of the two groups were compared at baseline (T1) at admission, 1 day before surgery (T2), 7 days after surgery (T3), and 30 days after surgery (T4). Results: At T2 and T4, the left ventricular ejection fraction (LVEF) levels and 6-min walking test (6-MWT) of the C and R groups were sharply higher than those at T1 (p < 0.05). At T3, the LVEF levels and 6-MWT distance of both groups were sharply lower than those at T1 (p < 0.05). Compared with the levels at T3, the LVEF levels; the 6-MWT; and the global, physical, emotional, and social levels of the C and R groups at T2 and T4 significantly increased (p < 0.05). At T1, the LVEF level; the 6-MWT; and the global, physical, emotional, and social levels of the C group was not statistically significant compared with those of the R group (p > 0.05). At T2, T3, and T4, the LVEF levels; the 6-MWT; and the global, physical, emotional, and social levels of the R group were sharply higher than those of the C group (p < 0.05). Conclusion: Early cardiac recovery training can effectively ameliorate the cardiac function and improve the quality of life of elderly patients undergoing CABG.
