In this study, Patients in the RLIC group will be treated with Renqiao Remote Ischemic Conditioning Device (Doctormate®) (200mmHg) twice daily and conventional medication; patients in the control group will be treated only with conventional medication. In the study, the RLIC treatment will be comprised of 5 cycles of bilateral upper limb ischemia and reperfusion, which will be induced by 2 cuffs placed around the upper arms respectively and inflated to 200mmHg for 5 minutes followed by 5 minutes of reperfusion by cuff deflation.
The primary objective of the study will be to determine whether remote limb ischemic conditioning (RLIC) together with conventional medication therapy compared with only medication therapy reduces the 3-month risk of composite cardio-cerebral vascular event in patients with a recent TIA or IS caused by occlusion of a cerebral artery.~After screening period, eligible patients will be randomly allocated into 2 groups.In addition, all participants receive an usual clinical therapy.
