NCT02796664

Brief Summary

This study is a 12-month, double-blind, randomized, placebo-controlled trial. The purpose of this study is to determine whether ginseng is effective in the prevention of atherosclerosis and subsequent ischemic stroke. High-risk patients with severe atherosclerosis in the major intracranial arteries and extracranial carotid artery were enrolled.

Outcome Measures

Primary Outcomes (2)

  • The Composite of Cerebral Ischemic Stroke and Transient Ischemic Attack

    The 1-year composite of cerebral ischemic stroke and transient ischemic attack downstream to an atherosclerotic lesion

    Twelve months after randomization.

  • Modified Rankin Scale

    Presence of other cerebro-cardiovascular morbidity or mortality assessed by aggravation of patient status (modified Rankin Scale). The modified Rankin Scale is ranging from 0 to 5. The higher scale indicates the worse outcome.

    Twelve months after randomization.

Secondary Outcomes (3)

  • The Changes in Volumetric Blood Flow (ml/Sec) in Intracranial Vessels.

    At randomization and twelve months after randomization.

  • The Changes of White Matter Hyperintensities.

    At randomization and twelve months after randomization.

  • Number of Participants With Changes of Parenchymal Ischemic Lesions

    At randomization and twelve months after randomization.

Other Outcomes (1)

  • Drug Compliance

    At twelve months after randomization.

You may qualify if:

  • Patients were included if they
  • were aged 20 to 80 years;
  • had occlusion or severe stenosis (≥ 70%) of extracranial carotid artery and major intracranial arteries (intracranial carotid artery, middle cerebral artery, anterior cerebral artery, intracranial vertebral, basilar, or posterior cerebral artery) as documented by cerebral catheter angiography;

Limitations and Caveats

1. The difficulty in determining the size of the study population due to the lack of previous studies. 2. The relatively short follow-up period considering chronic atherosclerotic disease. 3. The absence of surrogate biochemical markers to confirm ginsenosides' effects.
