Efficacy of Probucol Combined with Statins Treatment for Ischemic Stroke

Participants who opt for this group will receive guideline-recommended conventional lipid-lowering therapy. For those with a history of ischemic stroke (IS), myocardial infarction (MI), acute coronary syndrome within the past year, symptomatic peripheral artery disease, or two or more high-risk factors, the target LDL-C level will be set at 1.4 mmol/L. For other IS participants, the LDL-C target will be set at 1.8 mmol/L. All participants will receive moderate-intensity statin therapy as the primary treatment. If LDL-C levels are not adequately controlled, ezetimibe will be added. If lipid levels remain unsatisfactory, the addition of PCSK9 inhibitors will be considered. Moderate-intensity statins are defined as atorvastatin 10-20 mg or rosuvastatin 5-10 mg.

Participants who choose this group will receive Probucol in combination with guideline-recommended lipid-lowering therapy. Specifically, participants in this group will take 0.5 grams of Probucol twice daily alongside the conventional lipid-lowering therapy mentioned in Group 1. The combination of Probucol and conventional therapy aims to further improve lipid profile and address atherosclerosis.
