Remote Ischemic Conditioning for Acute Moderate Ischemic Stroke Due to Large Artery Atherosclerosis

Recruiting now · Not applicable

Conditions studied: Acute Ischemic Stroke

In brief

Large Artery Atherosclerosis is one of the most prevalent causes of stroke worldwide and is associated with a high risk of disability and recurrent strokes. Remote Ischemic Conditioning (RIC) is a promising therapy, and it has been recommended for further investigation in patients with acute ischemic stroke resulting from large artery atherosclerosis. The primary objective of this study is to assess the efficacy of RIC in patients suffering from acute moderate ischemic stroke due to large artery atherosclerosis.

Who can join

Age: 18 and older, up to 85. Sex: any. Healthy volunteers: not accepted.

You may qualify if…

• Male or female with age from 18 to 85 years old;
• Randomization must be within 48 hours after stroke symptom onset;
• Ischemic stroke confirmed by MRI diffusion-weighted imaging;
• NIHSS score 6-16, or 4-5 with disabling deficits at the time of randomization. The following typically should be considered disabling deficits: Complete hemianopsia (≥2 on NIHSS question 3) or severe aphasia (≥2 on NIHSS question 9), or visual or sensory extinction (≥1 on NIHSS question 11) or any weakness limiting sustained effort against gravity (≥2 on NIHSS question 6 or 7);
• Proven large vessel 50%-99% stenosis or occlusion by MRA, CTA or DSA in cervical or intracranial carotid artery, M1 or M2 segments of the middle cerebral artery, A1 segment of anterior cerebral artery, P1 segment of posterior cerebral artery, vertebral artery, or basilar artery. For patients with single cerebral infarction, when MRA indicates >50% stenosis rather than occlusion, CTA or DSA should be performed to exclude the risk of MRA overestimating stenosis severity. Acute neurological deficit and cerebral infarction are compatible with ischemia in the vascular territory;
• Pre-stroke modified Rankin Scale score (mRS) of 0-1;
• Signed Informed Consent obtained.

You may not qualify if…

• Thrombolysis or endovascular therapy performed or planned for index event;
• Suspected or confirmed cardioembolic source of stroke: i. The aetiology of cardiogenic embolism with high embolic potential, such as atrial fibrillation, atrial flutter, rheumatic mitral or aortic stenosis, artificial heart valve, left atrial myxoma, valve neoplasm, left ventricular wall thrombus, congestive heart failure, bacterial endocarditis, cardiomyopathy, myocardial infarction within previous 30 days; ii. Multiple cerebral infarctions in more than one vascular territory (e.g., bilateral MCA, or an MCA and a basilar artery) confirmed MRI diffusion-weighted imaging;
• Suspected or confirmed uncommon causes of cerebrovascular disorders: arterial dissection, Moyamoya disease, vasculitis disease, neurosyphilis, radiation induced vasculopathy, fibromuscular dysplasia, benign angiopathy of central nervous system, post-partum angiopathy, suspected vasospastic process, suspected recanalized embolus etc.;
• Subclavian artery stenosis ≥ 50% or subclavian steal syndrome;
• Refractory hypertension (defined as persistent systolic blood pressure >185 mmHg or diastolic blood pressure >110 mmHg after drug treatment);
• Evidence of intracranial tumor (except small meningioma), abscess, arteriovenous malformation;
• Patients with bleeding propensity: platelet count <50×10\^9/L; heparin was administered within 48 hours with APTT≥35s; on anticoagulant therapy with warfarin and International Normalized Ratio (INR) > 1.7;
• Undergoing hemodialysis or peritoneal dialysis, or known severe renal insufficiency with glomerular filtration rate <30 ml/min or serum creatinine >220 mmol/L (2.5mg/dl);
• Respiratory failure, including type I and type II;
• Any contraindication for Remote Ischemic Conditioning: severe soft tissue injury, fracture, peripheral vascular disease, arteriovenous fistula, or venous thrombosis in the upper limbs;
• Severe comorbid condition with life expectancy < 6 months；
• Current participation in any other investigational trial；
• Pregnancy；
• Patients not suitable for this clinical study considered by researchers.
