Summary

Objective: To evaluate the effects of a six-month intradialytic aerobic exercise program on left ventricular ejection fraction in patients with end-stage kidney disease undergoing maintenance hemodialysis. Materials and Methods Design: Open-label, single-center, quasi-experimental, single-group study with pre- and post-intervention measurements. Study setting: the outpatient hemodialysis unit of the National Institute of Medical Sciences and Nutrition Salvador Zubirán. Participants: Patients aged ≥18 years with chronic kidney disease on hemodialysis for at least three months, who are at their dry weight. Procedures: An echocardiogram will be performed post-hemodialysis. Subsequently, patients will undergo a 30-minute intradialytic aerobic exercise program at submaximal intensity during the second hour of dialysis, three times per week for six months. At the end of the six-month period, a post-hemodialysis echocardiogram will be repeated.
