Официальное название

Assessing Coronary Non-Culprit Plaque Early with Start of PCSK9 Inhibitors in Acute Myocardial Infarction

Обзор

This study is planned to start on January 2024. The goal of this clinical trial is to learn whether the perioperative administration (within 24 hours before or after primary PCI) of PCSK9 inhibitors can ameliorate plaque progression and adverse outcomes in patients with acute myocardial infarction (AMI). The main questions it aims to answer are: Can perioperative PCSK9 inhibition improve the plaque stability and inflammation of perivascular adipose tissue (index of plaque attenuation（IPA ）and perivascular fat attenuation index（FAI）) of non-target lesions? Researchers will compare PCSK9 inhibitors with statin plus ezetimibe therapy to evaluate the potential of PCSK9 inhibitors in mitigating the progression of non-target lesion plaques and reducing adverse cardiovascular events in patients with AMI. Participants will: Take PCSK9 inhibitors every two weeks or daily statin plus ezetimibe therapy. Conduct a follow-up examination with optical coherence tomography (OCT) or coronary computed tomography angiography (CTA) after 12 months. Record the occurrence of major adverse cardiovascular events.

Вмешательства

• Препарат PCSK9 inhibitor
  The patient used Trastuzumab 150mg within 24 hours before or after PCI, and then every two weeks for 12 months
• Препарат Statin+ezetimibe
  The patient used statins and ezetimibe within 24 hours before or after PCI, and then once a day for 12 months
• Поведенческое Blood lipid levels meet the recommended guidelines
  Early use of intensified lipid-lowering therapy during hospitalization led to a rapid decrease in blood lipids and met the recommended guidelines.
• Поведенческое Blood lipid levels don't meet the recommended guidelines
  The patient did not receive intensified lipid-lowering treatment during hospitalization or did not meet the recommended guidelines for blood lipids
