However, many strokes occur in patients with only mild-to-moderate stenosis. Evidence shows that it is not the degree of narrowing, but the \"vulnerability\" of the plaque-its internal composition-that determines rupture risk.\n\nHigh-risk (vulnerable) plaques have a large lipid-rich necrotic core, a thin fibrous cap, and intraplaque hemorrhage. Statins can lower cholesterol and stabilize plaques, but some patients still experience progression or recurrent events.\n\nPCSK9 inhibitors (such as evolocumab and alirocumab) are a new class of lipid-lowering drugs that reduce LDL cholesterol more strongly than statins alone. They may also have direct effects on the artery wall, improving plaque stability. Whether they can remodel vulnerable carotid plaques and how early this can be detected remains unclear.\n\nThis study uses high-resolution magnetic resonance imaging (HR-MRI), a non-invasive technique that visualizes plaque internal structure-including the lipid core, fibrous cap, and hemorrhage-to track changes over time.\n\nPurpose: The RESCUE study aims to determine whether adding a PCSK9 inhibitor to standard statin therapy can remodel and stabilize vulnerable carotid plaques, and to detect these changes early using HR-MRI.\n\nDesign: This is a single-center, prospective, randomized, controlled, open-label trial with blinded endpoint evaluation (PROBE design). 120 adults with carotid vulnerable plaques will be enrolled at Beijing Tsinghua Chang Gung Hospital and randomly assigned 1:1 to: (1) Experimental group (n=60): statin PLUS PCSK9 inhibitor (subcutaneous injection); (2) Control group (n=60): statin alone. Follow-up is 24 months. HR-MRI is performed at baseline, 6, 12, and 24 months. Blood samples are collected for lipid and inflammatory markers. HR-MRI analysis is performed by blinded radiologists.\n\nPrimary Outcome: Change in lipid-rich necrotic core volume by HR-MRI at 12 and 24 months.\n\nSecondary Outcomes: Fibrous cap thickness, intraplaque hemorrhage, remodeling index, LDL-C levels, inflammatory markers, and clinical events (stroke, TIA, cardiovascular death) over 24 months.\n\nStatus: Not yet recruiting.
