Making a limb transiently ischemic induces ischemic tolerance in distant organs such as the heart. This study aims to evaluate the feasibility, safety and initial efficacy of using briefly repetitive bilateral limb ischemic preconditioning (BLIPC) to protect the brain in octogenarians with symptomatic intracranial arterial stenosis.

Condition Intervention Phase
Bilateral Limb Ischemic Preconditioning
Intracranial Arterial Stenosis
Device: bilateral limb ischemic preconditioning (Doctormate, IPC-906X)
Phase 1

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Single Blind (Investigator)
Primary Purpose: Prevention
Official Title: Feasibility, Safety and Efficacy of RIPC for Symptomatic Intracranial Arterial Stenosis in Octogenarians

Further study details as provided by Capital Medical University:

Primary Outcome Measures:
  • objective signs of tissue or neurovascular injury [ Time Frame: 180 days after treatment ]
    objective signs of tissue or neurovascular injury felt to be due to cuff inflation, which was based on the judgment of the observers (blinded to study protocol) precluded continuation. Inspection included palpation of distal radial pulses, visual inspection (for local edema, redness, skin breakdown), and palpation for tenderness

  • levels of plasma biomarkers [ Time Frame: 180-day ]
    levels of plasma myoglobin at baseline and at the 1st, 15th and 30th day during BLIPC treatment were monitored

Enrollment: 58
Study Start Date: January 2008
Study Completion Date: December 2010
Primary Completion Date: December 2010 (Final data collection date for primary outcome measure)
