Intradialytic Exercise and Remote Ischaemic Preconditioning: a Cardioprotective Role ?

Summary

The aim of this clinical trial is to evaluate whether intermittent exercise and remote ischaemic preconditioning (rIPC) during haemodialysis (HD) can provide cardioprotection in adult patients (aged 20-79 years) undergoing HD for at least 3 months. The main questions to be answered are Does intermittent exercise or rIPC reduce myocardial stunning during HD? Do these interventions have a beneficial effect on haemorheology, arrhythmias, systemic inflammation and HD efficiency? The investigators will compare three HD sessions: no intervention (HD-CONT), with moderate-intensity intermittent exercise (HD-EX), and with rIPC using cuff inflation (HD-rIPC) to see if HD6EX and HD-rIPC approaches offer enhanced cardioprotection. Participants will: Undergo three randomised HD sessions. Participate in 5 blocks of moderate-intensity exercise or rIPC during the HD sessions. Have cardiac function and biomarkers assessed before, during and after HD.
