Abstract: Objective: To explore the effect of the early cardiac rehabilitation in patients after transcatheter aortic valve replacement (TAVR). Methods: Convenience sampling method was used and 76 patients after TAVR in a grade A tertiary hospital from October 2020 to February 2022 were included. The control group consisted of 38 patients admitted from October 2020 to June 2021, while the observation group included 38 patients admitted from July 2021 to February 2022. During the hospitalization, the control group received routine health education, the observation group received the early cardiac rehabilitation. Left ventricular ejection fraction (LVEF), 6-minute walking test (6MWT), the postoperative complications and the scores of Minnesota heart failure quality of life questionnaire (MLHFQ) were compared between the two groups on admission, the day of discharge and 1 month after discharge. Results: Two cases were dropped in the observation group. The results of repeated measure analysis of variance showed that there were significant interaction effects between time and group in the LVEF, 6MWT, the score of MLHFQ, physical domain and other domain of the two groups (P<0.05). Simple effect analysis showed that the LVEF and 6MWT of observation group were higher than that of the control group on the day of discharge and 1 month after discharge, meanwhile the score of MLHFQ, physical domain and other domain was lower than that of the control group and the difference was statistically significant (P<0.05).There was no significant difference in the scores of emotional domain and the rate of its complications (P<0.05). Conclusion: Early cardiac rehabilitation can improve the prognosis of patients after TAVR, but the recognition rate of its complications needs to be further improved.
