NCT04877041

Brief Summary

The purpose of this study is to determine the effect of a 12-week cycling during hemodialysis program on hemodialysis-induced myocardial stunning in adult individuals receiving hemodialysis.

Outcome Measures

Primary Outcomes (1)

  • Change in number of cardiac RWMA at peak hemodialysis stress (last 30 min HD) from baseline to 12 weeks measured using echocardiography

    Using standard left ventricular apical 2-, 3-, and 4-chamber views and left ventricular parasternal short-axis views collected by the same trained operator at each site 3 times during the mid-week hemodialysis session at each assessment time point as follows: baseline (pre hemodialysis), post-cycling exercise (or mid-dialysis in controls) and at peak hemodialysis stress (\~30 min prior to end of hemodialysis). Echocardiogram image analysis will be performed in London, ON using automated speckle-tracking analysis (EchoPAC-PC software version 110.1.3; GE Healthcare).

    Baseline to 12 weeks

Secondary Outcomes (16)

  • Change in post-hemodialysis high sensitivity Troponin T level from baseline to 12 weeks

    Baseline to 12 weeks

  • Change in difference between pre-hemodialysis and post-hemodialysis Troponin T from baseline to 12 weeks

    Baseline to 12 weeks

  • Change in number of cardiac RWMA at peak hemodialysis stress (last 30 min HD) from baseline to 16 weeks measured using echocardiography

    Baseline to 16 weeks

  • Change in severity of post-hemodialysis fatigue

    Baseline to 12 weeks

  • Change in Symptom Burden

    Baseline to 12 weeks

  • +11 more secondary outcomes

Study Arms (2)

Exercise (Intradialytic Cycling)

EXPERIMENTAL

Participants will receive a standardized baseline exercise counseling session as per control and then participate in a supervised intradialytic cycling program for 12-weeks

Behavioral: Intradialytic Cycling

Usual Care

NO INTERVENTION

Participants will receive a standardized baseline exercise counseling session. Participants in the control group will not undergo formal exercise intervention, but will not be prohibited from participating in exercise outside of hemodialysis. They will be asked to not to participate in intradialytic cycling during the study (16 weeks total).

Interventions

This intervention will consist of intradialytic cycling for 60 minutes 3 times per week for a total of 12 weeks.
