Early postoperative rehabilitation with 14-day treadmill training significantly increased exercise tolerance (median 50 to 75 W, p=0.002) and peak oxygen uptake (11.7 to 13.4 ml/kg/min, p=0.001).
Does early postoperative rehabilitation with aerobic exercise improve functional status and cardiac remodeling in patients after heart valve surgery?
Early postoperative aerobic exercise starting 8 days after heart valve surgery safely improves exercise tolerance and peak oxygen uptake without worsening hemodynamics.
p-value: p=0.002
Aim. To develop a program for early physical rehabilitation of inpatients after heart valve surgery and to evaluate its effectiveness and safety. Material and methods . The study included 80 patients with valvular heart disease (VHD) after elective on pump valve surgery. Patients in the control group (n=47) underwent standard cardiac rehabilitation after surgery; patients of the main group (n=33) additionally, starting from the 8th day after the intervention, had 14-day treadmill training with the program selection, taking into account the results of cycle ergometry spirometry (CES). A week after the operation and at the end of the training course (median, 24 days after the operation), cardiac remodeling and functional status was assessed according to echocardiography and CE, respectively. Results. For 7 days after surgery, patients of both groups were comparable. During physical training in the main group, there were no lifethreatening cardiac arrhythmias, episodes of ischemia, desaturation, as well as intracardiac hemodynamics deterioration. With a 14-day training, CES showed a significant increase in exercise tolerance (ET) in the main group from a median of 50 to 75 W (p=0,002), peak oxygen uptake (VO 2 peak) from 11,7 to 13,4 ml/kg/min (p=0,001). For 24 days after surgery in the control group, there was a trend towards improvement in ET and VO 2 peak, but without significant changes (p=0,09/p=0,08). Conclusion . Early inhospital rehabilitation, including physical training of moderate intensity with an individual treadmill speed and incline angle, starting from day 8 after surgery, showed effectiveness and safety in the form of an increase in ET and VO 2 peak, while not worsening hemodynamic parameters.
Lyapina et al. (Fri,) conducted a other in Valvular heart disease after elective on-pump valve surgery (n=80). Early physical rehabilitation with treadmill training vs. Standard cardiac rehabilitation was evaluated on Exercise tolerance (ET) and peak oxygen uptake (VO2 peak) (p=0.002). Early postoperative rehabilitation with 14-day treadmill training significantly increased exercise tolerance (median 50 to 75 W, p=0.002) and peak oxygen uptake (11.7 to 13.4 ml/kg/min, p=0.001).
