简要总结
Although the clinical efficacy of LDL-cholesterol lowering therapy has been proven with strong evidences and emphasized, there are also growing concerns that intensive lipid-lowering therapy would be related to increased risk of adverse effects. In addition, statin potency from recent guidelines was set from the studies composed of mainly Caucasian population, although there is an inconsistency of statin effect according to ethnicity. Asian population showed more profound LDL reduction not only from high potent statin but also from moderate to low potent statin. Conventional strategies for lowering LDL-cholesterol focused on statins, therefore doubling of previously described dose of statin would be common way in patients with inadequate LDL-cholesterol levels. Adding ezetimibe will be an alternative strategy not only to lower LDL-cholesterol level and also to reduce the need of dosage of high-intensity statin to achieve sufficient LDL-cholesterol lowering effect. However, studies regarding the effect of intensive-targeting of lipid-lowering therapy and therapy regimens are lacking. Thus, on these basis, we sought to evaluate whether intensive-targeting of lipid-lowering therapy will have more prominent beneficial effect compared to conventional-targeting in patients with documented ASCVD with either an ezetimibe/statin combination therapy or a statin monotherapy.
详细描述
All eligible patients who have documented ASCVD will be enrolled according to inclusion/exclusion criteria after voluntary agreement with informed consent. At the time of enrollment, we will stratify all patients according to LDL-cholesterol <100mg/dL, DM, and acute coronary syndrome, and randomly assign them in two groups according to LDL-cholesterol targeting level with a 1:1 ratio: "Intensive-targeting group" vs. "Conventional-targeting group". In addition, patients in each group will be randomly assigned to receive two lipid-lowering therapy regimen with a 1:1 ratio: "Ezetimibe/Statin combination therapy" vs. "Statin monotherapy". Patients allocated to each treatment group will receive lipid-lowering therapy with following protocols.
