About this trial

This is an interventional prevention trial for Cerebrovascular Disease focused on measuring ischemic cerebral vascular disease, stroke secondary prevention, remote ischemic preconditioning

Eligibility Criteria

18 Years - 80 Years (Adult, Older Adult)All SexesDoes not accept healthy volunteers

Inclusion criteria:

  1. Patients with stroke or transient ischemic attack (TIA) within 180 days and the neurologic deficits were well matched to the territory of the stenosed artery, with intracranial arterial stenosis of at least 50% by angiography, at least 70% by ultrasound, or at least 70% by computed tomographic angiography (CTA) or magnetic resonance angiography (MRA)
  2. Age between 18 to 80 years old
  3. Trial of Org 10172 in Acute Stroke Treatment-1 (TOAST-1) subtype
  4. National Institutes of Health Stroke Scale (NIHSS) score 0-15, and Modified Rankin Scale (mRS) score 0-4.
  5. ABCD2 score between 6 to 7
  6. Stable vital signs, normal hepatic and renal functions,
  7. No hemorrhagic tendencies.

Exclusion criteria:

  1. Within 72 hrs of intra-artery or intravenous thrombolysis
  2. Intracranial hemorrhage or large area of cerebral infarction (more than 1/3 middle cerebral artery perfusion territory)
  3. Any soft tissue, orthopedic, or vascular injury, wounds or fractures in extremities which may pose a contraindication for application of the preconditioning cuffs
  4. Acute myocardial infarction
  5. Systolic blood pressure more than 200 mmHg after drug control
  6. Peripheral blood vessel disease
  7. Hematologic disease
  8. Severe hepatic and renal dysfunction
  9. Severe or unstable concomitant disease
  10. Cannot tolerate BLIPC or without informed consent
  11. Patients who did not complete the whole treatment procedure.

Arms of the Study

Arm 1

Arm 2

Arm Type

Experimental

No Intervention

Arm Label

RIPC+stroke secondary prevension

stroke secondary prevention

Arm Description

Procedure/Surgery: Remote Ischemic Preconditioning (RIPC) The detail of RIPC included five cycles of bilateral upper limbs 5/5 min. of ischemia and reperfusion alternation. Limb ischemia was induced by inflating tourniquets to 200 mmHg. This process was placed on both arms every day. Procedure:stroke secondary prevention(Such as Antiplatelet therapy, Cholesterol-lowering therapymaintain blood pressure and blood sugar normal)

Procedure:stroke secondary prevention(Such as Antiplatelet therapy, Cholesterol-lowering therapymaintain blood pressure and blood sugar normal)

Outcomes

Primary Outcome Measures

Blood Pressure and Heart Rates;
Plasma Biomarkers of Coagulation and Fibrinolysis
blood samples were collected one hour after every times of BLIPC procedure ended, and assayed with the immuno-turbidimetry assay on the coagulation laboratory autoanalyzer
Number of Patients Who Got New Brain Lesions
We compared the number of patients who got new lesions in the Diffusion-weighted magnetic resonance imaging (DWI-MRI)

Secondary Outcome Measures

The Time Point Until the First Stroke Recurrence,
These patients underwent MRI/DWI at the time of first recurrence; patients without symptoms recurrence underwent follow-up MRI/DWI at 300 days.
Brain Perfusion Improvement Are Evaluated With SPECT and TCD
Brain perfusion status were evalvated by SPECT SPECT scanning was performed using a dual headed rotating gamma camera at 30 minutes after intravenous 99mTc-ECD (25mCi) bolus injection and at 40 minutes after 18F -FDG bolus injection.
