PCSK 9 Inhibitor Added to High-Intensity Statin Therapy to Prevent Cardiovascular Events in Patients With ACS After PCI

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, re-hospitalization due to acute coronary syndromes or heart failure, or any ischemia-driven coronary revascularization) in patients with acute coronary syndrome and multiple lesions. Alirocumab was used before June 10, 2025; Tafolecimab has been used from June 10, 2025 onward.
