Effects of Remote Ischemic Preconditioning on Components of Peripheral Blood (EMINENT)
Study Details
Study Description
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.

Detailed Description
This study will recruit 50 healthy individuals to undergo remote ischaemic preconditioning training for 7 consecutive days, and routine biological specimens from subjects before and after the intervention will be collected. The characteristics of different fractions of blood and urine and faecal specimens from subjects at different time points before and after ischaemic preconditioning will be examined to investigate the effects of remote ischaemic preconditioning on the characteristics of peripheral blood, urine and faeces in healthy adults. It also provides evidence for improving the efficiency of clinical transfusion and blood conservation by comparing the differences in blood fractions under different preservation conditions.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Experimental: Healthy population Subjects aged 18 to 45 years and in good health agree to participate in the clinical trial and sign an informed consent form. |
Device: Remote ischaemic preconditioning
The participant 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 will be performed twice daily (once in the morning and once in the evening), and heart rate and blood pressure before and after each training will be recorded for 7 days.

Outcome Measures
Primary Outcome Measures
- Change of peripheral blood characteristics [Baseline (before training), the end of the training day (7th day from the start of training), 3rd day after the end of training]
Peripheral blood characteristics at different remote ischemic preconditioning, training time points, including different fractions and their characteristics expressed by the results of blood tests.
Secondary Outcome Measures
- Incidence of adverse events [During day 1 to 7 of training.]
Incidence of adverse events related to remote ischemic preconditioning training. The adverse events were decided according to the medical records.
- Change of urine characteristics [Baseline (before training), the end of the training day (7th day from the start of training), 3rd day after the end of training]
Effect of RIPC training on urine characteristics, expressed by the urine test results.
- Change of faecal characteristics [Baseline (before training), the end of the training day (7th day from the start of training), 3rd day after the end of training]
Effect of RIPC training on faecal characteristics, expressed by the fecal test results.
- Change of blood pressure [Before and after the training in day 1,2,3,4,5,6,7 of training.]
Changes in blood pressure at different remote ischemic preconditioning training time points, measured with sphygmomanometer.
- Change of heart rates [Before and after the training in day 1,2,3,4,5,6,7 of training.]
Changes in heart rates at different remote ischemic preconditioning training time points, measured with stopwatch.
