简要总结

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.

结局指标

主要结局

Change in regional myocardial stunning.

时间窗: From enrollment to the end of treatment at 7 weeks

The investigators will use echocardiography to assess the number of left ventricular myocardial segments (using a 18-segment model), that demonstrate a reduction in longitudinal deformation greater than 20% at peak stress during hemodialysis, relative to baseline measurements obtained at the start of the dialysis session. Their aim is to compare changes in regional wall motion abnormalities across three experimental conditions: - Standard hemodialysis (HD-CONT), - Hemodialysis with intradialytic intermittent physical exercise (HD-EX), - Hemodialysis with an intradialytic ischemia/reperfusion sequence applied to the upper limb (HD-RIPC). Patients will participate in all three conditions in a randomized order. A two-week period of standard dialysis will separate the execution of two consecutive sessions.
