INTRODUCTION: Patients on hemodialysis (HD) present high mortality from cardiovascular complications and high morbidity, including decreasing functional capacity and quality of life.
OBJECTIVE: To analyze clinical and laboratory responses of patients in HD to intradialytic cardiopulmonary rehabilitation on an outpatient basis.
METHODS: We evaluated 14 patients in a prospective study for 8 months using cardiopulmonary rehabilitation protocol (CRehab) consisted of intradialytic aerobic exercise with a cycle ergometer. We analyzed heart rate (HR), systolic (SBP) and diastolic blood pressure (DBP), peripheral oxygen saturation (SpO2) and modified Borg scale. We evaluated cardiac function by echocardiogram, functional capacity by six minutes walk test (6MWT), and quality of life by SF-36 survey, before and after CRehab. Biochemical data and KT/Vsp were collected form medical records.
RESULTS: During CRehab, the results of HR, SBP, DBP, SpO2 and Borg scale showed no significant changes. 6MWT test showed progressive increase in the distance covered (p < 0.001) as well as a reduction in the scale of Borg post-6MWT (p = 0.009). There was no significant change in any biochemical data or in KT/Vsp. There was increase in left ventricular ejection from 65.7 ± 10.2% to 73.6 ± 10.1% (p = 0.028) and in left ventricular diastolic diameter (p = 0.027). According to SF-36 survey, patients showed improvement in three areas: physical role functioning (p = 0.012), bodily pain (p = 0.007) and vitality (p = 0.009).
CONCLUSION: The intradialytic CRehab applied in this population was safe and allowed objective improvement of functional capacity and exercise tolerance, subjective improvement in the perception of effort, significant increase in cardiac function and better quality of life in different domains.
