The effect of cardiac rehabilitation at 4 weeks postoperatively on quality of life in patients treated with totally thoracoscopic ablation.

There is a lack of evidence on the effect of exercise-based cardiac rehabilitation (EBCR) in patients treated with total thoracoscopic ablation (TTA) for atrial fibrillation (AF). Our study investigated the efficacy and safety of postoperative exercise intervention in patients recovering from TTA. Twenty-four patients participated in the study, and were divided into the two groups, exercise group (EG) (n=12) and control group (n= 12). Patients in EG performed the exercise intervention including the aerobic and resistance exercise program twice a week for 8 weeks, which was used as a hospital-based cardiac rehabilitation for the out-patient. A cardiopulmonary exercise test was administered to evaluate aerobic exercise capacity, and qualitative aspect of patient's life was assessed using the Short Form 36 questionnaires to compare pre and postoperative wellness of patient's life. Although there was an increase of VO2peak (peak oxygen uptake) after exercise intervention, no significant improvement was found (P=0.055). Two of 4 physical health scores (role-physical, P=0.013 and general health, P=0.05) and three of four mental health scores (vitality, P=0.027, social function, P=0.016, and mental health, P=0.003) were significantly improved after 8 weeks of EBCR. Each summarized scale in the physical (P=0.022) and mental (P= 0.004) survey section was also significantly improved in postoperative assessment compared to the preoperative one. In this context, we concluded that EBCR initiated at the time point of 4th week after TTA operation can guarantee the secure postoperative physical activity, and the 8 weeks of EBCR can effectively improve the quality of life in AF Patients.
