About this trial

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.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

The subject, or their legal guardian, must have a clear understanding of the trial's design and treatment procedures. They must provide written informed consent before any trial-specific tests or procedures are conducted.

Both male and female subjects aged ≥18 years.

Low-density lipoprotein cholesterol ≥70 mg/dL (≥1.8 mmol/L) in patients who have been on a stable high-intensity statin regimen for at least 4 weeks before enrollment.

Low-density lipoprotein cholesterol ≥90 mg/dL (≥2.3 mmol/L) in patients who have been on a moderate or low-intensity statin regimen before enrollment.

Disqualifiers

Fasting serum triglyceride levels exceeding 400 mg/dL (exceeding 4.52 mmol/L) before randomization.

Coronary artery disease is located within a saphenous vein graft or an arterial graft.

Residual diameter stenosis greater than 50% as determined by visual examination after percutaneous coronary intervention of the culprit lesion.

TIMI (Thrombolysis in Myocardial Infarction) flow less than 3 in the culprit vessel after PCI.
