Detailed Description
In this study, 100 patients with carotid artery stenosis receiving carotid endarterectomy are included in our center in China according to the principle of random, and parallel control. The experimental group receive basic treatment and remote ischemic conditioning for 200mmHg, 2 times per day for 6 consecutive days. The control group receive basic treatment and remote ischemic conditioning control for 60mmHg, 2 times per day for 6 consecutive days. Two groups will be followed up for 90 days to evaluate the safety and efficacy of remote ischemic conditioning in patients with carotid artery stenosis receiving carotid endarterectomy.
Study Design
Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Active Comparator: RIC+CEA+Standard medical treatment Remote ischemic conditioning (RIC) is induced by 5 cycles of 5 min of bilateral upper limbs ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 200 mmHg. RIC will be conducted twice daily for 6 consecutive days after enrollment. Additionally, the patients will be treated with carotid endarterectomy (CEA) and standard medical treatment according to the Chinese guideline for the secondary prevention of ischemic stroke and transient ischemic attack 2022. |
Procedure: Remote ischemic conditioning
Remote ischemic conditioning (RIC) is induced by 5 cycles of 5 min of bilateral upper limbs ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflations of a blood pressure cuff to 200 mmHg.

| Placebo Comparator: Sham RIC+CEA+Standard medical treatment Remote ischemic conditioning (RIC) is induced by 5 cycles of 5 min of bilateral upper limbs ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflation of a blood pressure cuff to 60 mmHg. RIC will be conducted twice daily for 6 consecutive days after enrollment. Additionally, the patients will be treated with carotid endarterectomy (CEA) and standard medical treatment according to the Chinese guideline for the secondary prevention of ischemic stroke and transient ischemic attack 2022. |
Procedure: Sham remote ischemic conditioning
Remote ischemic conditioning (RIC) is induced by 5 cycles of 5 min of bilateral upper limbs ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflations of a blood pressure cuff to 60 mmHg.

Outcome Measures
Primary Outcome Measures
- Proportion of patients who got ≥1 new Diffusion Weighted Imaging (DWI)-positive lesions on post-treatment magnetic resonance imaging (MRI) Scans. [6 days]
Patients underwent magnetic resonance imaging (including DWI)at baseline and 6 days after randomization.
Secondary Outcome Measures
- The number of new Diffusion Weighted Imaging (DWI)-positive lesions on post-treatment magnetic resonance imaging (MRI) Scans. [6 days]
Patients underwent magnetic resonance imaging (including DWI)at baseline and 6 days after randomization.
- The volume of new Diffusion Weighted Imaging (DWI)-positive lesions on post-treatment magnetic resonance imaging (MRI) Scans. [6 days]
Patients underwent magnetic resonance imaging(including DWI) at baseline and 6 days after randomization.
- Number of patients with cerebrovascular events, cardiovascular events or death. [90±7 days]
Cerebrovascular events included ischemic stroke, transient ischemic attack (TIA), cerebral hemorrhage. Cardiovascular events included angina and myocardial infarction. Death included any reason caused death.
- Proportion of patients with any side effects of Remote ischemic conditioning (RIC) treatment. [6 days]
The side effects referred to any side effects of RIC or sham RIC treatment, not including the sides effect of medications and Carotid Endarterectomy (CEA).
