Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Patients issued from dialysis units (clinic)

Randomised, controlled, crossover, bicentric, single-blind, prospective, open-label, superiority clinical trial comparing 3 dialysis modalities:

Procedure A: Standard dialysis

Procedure B: Dialysis with intradialytic intermittent physical exercise

Procedure C: Dialysis with intradialytic ischaemia/reperfusion sequence of the upper limb

Each subject will realize the 3 sessions in a random order.

Group Type EXPERIMENTAL

Remote ischaemic preconditioning

Intervention Type OTHER

The dialysis protocol integrates a sequence of five ischaemia/reperfusion blocks applied to the upper limb. Each block consists of a 5-minute period of cuff inflation at a supra-systolic pressure individualized to each patient-20 mmHg above the limb occlusion pressure-followed by a 25-minute period of cuff deflation. This intervention begins 30 minutes after the start of dialysis and is referred to as hemodialysis remote ischaemic preconditioning (HD-rIPC).

Exercise

Intervention Type OTHER

The exercise protocol consists of five sequential bouts of physical activity, initiated 30 minutes after the start of dialysis. Each bout comprises a 5-minute cycling exercise at moderate intensity, corresponding to a Borg Scale rating of 12-14, followed by a 25-minute passive recovery phase. This structured intervention is referred to as hemodialysis exercise (HD-EX).

standard dialysis

Intervention Type OTHER

The hemodialysis control condition (HD-CONT) consists of standard hemodialysis treatment without the integration of any additional interventions, such as exercise or ischaemia/reperfusion protocols.
