Brief Summary

The aim of this study is to investigate the effects of remote ischaemic preconditioning on the peripheral blood characteristics of healthy adults and to explore the possible mechanisms for improving ischaemia/reperfusion injury and its protective effects on the cardiovascular system.

Conditions

Ischemic Preconditioning

Keywords

Remote ischemic preconditioning; Peripheral blood; Healthy adults

Outcome Measures

Primary Outcomes (1)

• Changes in the expression levels of cardiovascular disease-related molecules

  Changes in the expression levels of cardiovascular disease-related molecules between participants in group A (intermediate RIPC training, once a day) or B (intense RIPC training, twice a day)

  Baseline (before training), the end of the training day (7th day from the start of training), 7th day after the end of training

Secondary Outcomes (5)

• Longitudinal within-group changes in the expression of cardiovascular disease-related molecules

  Baseline (before training), the end of the training day (7th day from the start of training), 7th day after the end of training

• Change of blood pressure

  Baseline (before training), during the training session (day1-7), 7th day after the end of training.

• Change of heart rates

  Baseline (before training), during the training session (day1-7), 7th day after the end of training

• Incidence of adverse events

  During day 1 to 7 of training.

• Changes in the Plasma Proteomic Profile

  Baseline, Day 7, and Day 14

Study Arms (3)

Group A (high-frequency group )

EXPERIMENTAL

Subjects aged 18 to 45 years and in good health agree to participate in the clinical trial and sign an informed consent form. The high-frequency remote ischemic preconditioning (RIPC) group will undergo RIPC training continuously for seven days, twice daily, with each session consisting of four cycles of 5 minutes of ischemia followed by 5 minutes of reperfusion.

Device: Remote ischaemic preconditioning

Group B (low-frequency group )

EXPERIMENTAL

Subjects aged 18 to 45 years and in good health agree to participate in the clinical trial and sign an informed consent form. The low-frequency RIPC group will follow the same cycle and compression pattern but will train only once a day.

Device: Remote ischaemic preconditioning

no-intervention control group

NO INTERVENTION

Participants in the no-intervention control group will not receive RIPC training or any other study-related intervention. They will undergo blood collection at the corresponding time points: baseline, Day 7, and Day 14.

Interventions

Remote ischaemic preconditioning DEVICE

The participants rested in the supine position for 5 minutes, then turn on the ischaemic preconditioning apparatus and place the automatically programmed blood pressure cuff on both upper arms of the participant, pressurize to 200 mmHg, pressurize for 5 minutes, rest for 5 minutes, perform 4 cycles for a total of 40 minutes each time. The training for participants in group A will be performed once daily, while for participants in group B the training will be performed twice daily. And heart rate and blood pressure before and after each training will be recorded for 7 days.

Group A (high-frequency group ); Group B (low-frequency group )
