Brief Summary

Stroke is one of the most threatening causes of mortality and disability worldwide. High risk non-disabling ischemic cerebrovascular events (HR-NICE), defined by mild stroke complicating with greater than 50% atherosclerotic stenosis in intracranial or extracranial arteries, is more likely to develop severe stroke in future. Currently, the clinical treatment for HR-NICE patients is limited to dual antiplatelet therapy or endovascular treatment, both of which are taken controversially due to the side effect or high risk. Enhanced external counterpulsation (EECP) is an established non-invasive treatment for circulatory support. By inflating repeatedly and sequentially from calves to hips in the early diastolic phase of every cardiac cycle, EECP has been demonstrated to increase the shear stress of blood vessels, enhance the collateral circulation and improve brain perfusion in patients with stroke. However, few studies have devoted exclusively to patients with HR-NICE. It is not clear whether EECP can improve the clinical performance or reduce the rate of recurrent stroke in 90 days. In this trial, HR-NICE patients will be divided into two groups according to true or sham EECP treatment. Based on multi-model magnetic resonance imaging, the investigators explore the central neural characteristic before and after EECP treatment.

Outcome Measures

Primary Outcomes (1)

  • the change of stroke impact scale (SIS)

    Stroke Impact Scale (SIS) is an evaluation of stroke severity affecting daily life and health. It includes 59 items in 8 domains among strength, hand function, mobility, activities of daily living, memory, communication, emotion and social participation. Each item is scored on a scale of 1 - 5 and each domain is scored on a scale of 0 - 100 after conversion. The sum score of 8 domains is set as the total of SIS. A higher score corresponds to a better outcome. In this trial, SIS is evaluated before and after the EECP treatment course, total score of each evaluation is calculated and the change of them is set as the primary outcome measure.

    baseline(the day before the first EECP treatment); after a course of EECP treatment(14 days)

Secondary Outcomes (1)

  • the change of cerebral perfusion
