5. Study Description

Brief Summary
The primary objective was to evaluate the effect of PCSK 9 Inhibitor (initiated within 4 h from PCI for the culprit lesion) with high-intensity statin treatment, compared to placebo with high-intensity statin treatment, on cardiovascular events (including cardiovascular death, myocardial infarction, stroke or transit ischemic attack, re-hospitalization due to unstable angina or heart failure, or any ischemia-driven coronary revascularization) in patients with acute coronary syndrome and multiple lesions.
Detailed Description
Patients with acute coronary syndrome (ACS) are at high-risk. ACS patients are commonly associated with multiple lesions or multivessel disease. Percutaneous coronary intervention (PCI) is an effective treatment for culprit lesions in ACS. Statin at high-intensity is recommended by current guidelines in order to prevent/slow the progression of non-culprit disease or restenosis. PCSK9 inhibitor serves as the most powerful medication in lowering LDL via promoting the expression of LDL receptors in the liver. However, if the combination of PCSK9 inhibitor with high-intensity statin treatment could significantly reduce the cardiovascular events in patients with ACS who underwent PCI remains unknown.
