Objective: To explore the application effect of phase Ⅰ cardiac rehabilitation (CR-Ⅰ) combined with cognitive behavioural therapy (CBT) on patients after aortic valve replacement (AVR).
Methods: This study retrospectively analysed the data of 441 patients after AVR in our hospital from January 2020 to May 2023. A total of 38 patients who did not meet the inclusion criteria were excluded. A total of 403 patients were included. In accordance with different postoperative management schemes, the included patients were divided into the reference group (n = 202, received CR-Ⅰ) and the observation group (n = 201, received CR-Ⅰ+CBT). The cardiac function, exercise capacity and mental health of the two groups were compared.
Results: Before management, both groups had no significant differences in left ventricular end diastolic diameter (LVEDD), left ventricular end systolic dimension (LVESD), left ventricular ejection fraction (LVEF) and six-minute walking test (6MWT) scores (p > 0.05). At discharge and 3 months after discharge, the observation group had significantly lower LVEDD and LVESD and remarkably higher LVEF and 6MWT scores than the reference group (p < 0.001). The proportions of autonomous activity in bed within 3-4 days after surgery, autonomous out-of-bed activity within 8-10 days after surgery and autonomous walking 200 m within 12-15 days after surgery were distinctly higher (p < 0.001) and the incidence of adverse reactions was overtly lower (p < 0.001) in the observation group than in the reference group. Before management, both groups had no significant difference in their scores on the State-Trait Anxiety Inventory (STAI) (p > 0.05). At discharge and 3 months after discharge, the observation group had lower STAI scores than the reference group (p < 0.001).
Conclusion: CR-Ⅰ combined with CBT effectively improves the cardiac function, independent exercise capacity and mental health level of patients after AVR and provides a new direction for the formulation and selection of follow-up clinical management.
