Objective To investigate the effect of bed rehabilitation bicycle on postoperative recovery of patients undergoing cardiac valvular surgery.

Methods A total of 102 cases of postoperative patients were selected randomly from October 2018 to October 2019, as the observation group, and 102 cases of patients who did not participated in routine physiotherapy were considered as the control group in the same period. The activity time after getting out of bed, brain natriuretic peptide (BNP), left ventricular ejection fraction (LVEF), and anxiety and depression scores of patients in the two groups were compared.

Results The activity time after getting out of bed of patients was longer in the observation group than that in the control group (P < 0.000 1), cardiac function indicators such as BNP and LVEF were improved significantly compared with those in the control group (P < 0.000 1), anxiety and depression scores decreased compared with those in the control group (P < 0.000 1).

Conclusions Early postoperative bed bike exercise can effectively promote the recovery of cardiac function, prolong the activity time after getting out of bed, improve anxiety and depression, which further promote the early recovery of postoperative patients.
