Remote ischemic conditioning: The RIC protocol involves bilateral upper-arm cuff inflation to 200 mmHg (5-min inflation/5-min deflation, 5 cycles) performed 1-2 times daily, starting 3 days before CAS and continuing for 12 months post-procedure.
Study summary
Remote ischemic conditioning (RIC) has emerged as a promising non-invasive strategy to protect the brain, with evidence suggesting its benefit in patients with carotid artery stenting (CAS). However, the long-term benefit and safety of chronic RIC in this population remain unknown. This trial aims to evaluate whether chronic RIC reduces the incidence of major vascular events and improves clinical outcomes in high-risk patients with carotid artery stenosis who received CAS.
