Abstract
Objective: To evaluate the effectiveness of supervised cardiac rehabilitation for conservative chronic kidney disease（CKD）. Method: We surveyed 35 patients with renal dysfunction who completed 5 months of a cardiac rehabilitation program. We compared changes in eGFR, oxygen consumption, 6-minute walking distance, and grip strength at the beginning and end of cardiac rehabilitation programs. And so, we examined the related factors of eGFR change. Results: Oxygen consumption, 6-minute walking distance, grip strength and eGFR after 5 months of the program were significantly improved（oxygen consumption: 10.2 ± 1.7→12.0 ml/min/kg, 6-minute walking distance: 387.9 ± 74.2→427.8 ± 84.3 m，grip strength: 29.6 ± 7.6→31.7 ± 7.2 kg, eGFR: 48.2 ± 10.2→50.5 ± 12.8 ml/min/1.73 m²）. After 5 months of the program, 23 patients（65.7%）were improved in the renal function. The factors related to eGFR improvement were high eGFR and grip strength before the 5-month program and diet adherence in this period. Conclusion: The renal function of CKD patients might be improved by comprehensive cardiac rehabilitation. We recommend strict nutrition management and early exercise therapy for CKD patients.
