What this trial studies

This study investigates the effects of a 12-week cycling program conducted during hemodialysis sessions on myocardial stunning in adults with end-stage kidney disease. Patients undergoing chronic hemodialysis often experience fatigue and increased risk of cardiac complications due to ischemic cardiac injury during treatment. By utilizing echocardiography, the study aims to assess how intradialytic aerobic exercise can mitigate these cardiac issues and improve overall patient outcomes. Participants will engage in cycling while receiving hemodialysis to evaluate its impact on heart function and related symptoms.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older who have been on maintenance hemodialysis for at least three months and are assessed as safe to exercise.

Not a fit: Patients with recent acute coronary syndrome, unstable arrhythmias, or severe shortness of breath may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce cardiac complications and improve quality of life for patients undergoing hemodialysis.

How similar studies have performed: Previous studies have indicated that intradialytic exercise can reduce myocardial stunning, suggesting potential success for this approach.
