Outcome Measures

Primary Outcomes (3)

  • Phase Difference(PD) in Degree

    PD is a dynamic cerebral auto-regulation parameter derived from transfer function analysis.

    within 7 days of RIC

  • Differences of blood pressure variability (BPV) in Degree after in-hospital remote ischemic conditioning finished between two groups

    BPV is defined as blood pressure oscillations in relation to the mean values.

    within 7 days of RIC

  • Differences of heart rate variability (HRV) in Degree after in-hospital remote ischemic conditioning finished between two groups

    HRV is defined as heart rate oscillations in relation to the mean values.

    within 7 days of RIC

Secondary Outcomes (4)

  • Differences of BPV in Degree after 3-4 days remote ischemic conditioning treatment between two groups

    3-4 days after RIC

  • Differences of HRV in Degree after 3-4 days remote ischemic conditioning treatment between two groups

    3-4 days after RIC

  • PD in Degree

    3-4 days after RIC

  • Differences in modified Rankin Scale (mRS) Score between two groups

    3 months

Study Arms (2)

RIC+Standard medical treatment

ACTIVE COMPARATOR

Remote ischemic conditioning (RIC) is induced by 4 cycles of 5 min of healthy upper limb ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflations of a blood pressure cuff to 200 mmHg. RIC will be conducted twice daily during the period of hospitalization. Besides, the patients will be treated with standard medical treatment according to consensus on diagnosis and treatment of cerebral small vessel disease in China 2015, including antiplatelet aggregation and lipid-stabilizing drugs as well as neurotrophic and circulation improving treatment.

Procedure: Remote ischemic conditioning

Sham RIC+Standard medical treatment

PLACEBO COMPARATOR

Remote ischemic conditioning (RIC) is induced by 4 cycles of 5 min of healthy upper limb ischemia followed by 5 min reperfusion. Limb ischemia was induced by inflations of a blood pressure cuff to 60 mmHg. RIC will be conducted twice daily during the period of hospitalization. Besides, the patients will be treated with standard medical treatment according to consensus on diagnosis and treatment of cerebral small vessel disease in China 2015, including antiplatelet aggregation and lipid-stabilizing drugs as well as neurotrophic and circulation improving treatment.
