Study summary

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.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

  • Experimental
    PCSK9 inhibitor group

    In this group, patients will receive PCSK9 inhibitor treatment

    Drug: PCSK9 inhibitor · Behavioral: Blood lipid levels meet the recommended guidelines

  • Active comparator
    Statin+ezetimibe group

    In this group, patients will receive statin and ezetimibe treatment

    Drug: Statin+ezetimibe · Behavioral: Blood lipid levels don't meet the recommended guidelines

Interventions

  • The patient used Trastuzumab 150mg within 24 hours before or after PCI, and then every two weeks for 12 months

  • DrugStatin+ezetimibe

    Drug pages: Statins · Ezetimibe

    The patient used statins and ezetimibe within 24 hours before or after PCI, and then once a day for 12 months

  • BehavioralBlood 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.

  • BehavioralBlood 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

What researchers measure

Primary outcomes

  1. Changes in Index of Plaque Attenuation (IPA) measured by OCT for non-culprit lesions at baseline and 12 months of follow-up.

    IPA is a quantitative analysis tool based on OCT technology to evaluate plaque stability.

    Time frame: 12 months

  2. Changes in pericoronary artery fat attenuation index (FAI) measured by CCTA for non-culprit lesions at baseline and 12 months of follow-up

    FAI is a quantitative indicator of inflammation in perivascular adipose tissue measured by CCTA.

    Time frame: 12 months

Secondary outcomes

  1. Progress of target lesion plaques

    To assess plaque progression, OCT evaluation will include fiber cap thickness, lipid core amplitude, minimum lumen area, and minimum lumen diameter. CCTA evaluation will include CAD-RADS grade , plaque volume, plaque properties, calcification score, epicardial fat volume and plaque attenuation. Notes: CAD-RADS indicates Coronary Artery Disease-Reporting and Data System, which range from 0 to 5. The higher CAD-RADS grade, the more severe of the coronary stenosis.

    Time frame: 12 months

  2. The overall incidence of the first major adverse cardiovascular events (MACEs) within 12 months in different treatment groups

    MACEs was defined as the composite of myocardial infarction, ischemic stroke, cardiovascular death and coronary revascularization

    Time frame: 12 months

  3. The proportion of LDLC at each visit node that meets the recommended guidelines and the changes compared to baseline

    Time frame: 1week;1months;3 months; 6 months; 9 months; 12 months

  4. Changes in inflammatory factors (interleukin 6, C reaction protein) at each visit node compared to baseline

    Time frame: 1week;1months;3 months; 6 months; 9 months; 12 months

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Apr 2025; primary completion for Dec 2026, 20 months later.

Of 322 non-industry interventional studies with no phase under Myocardial Infarction, half reached primary completion within 35 months of starting (the median), counting those still running; a quarter within 14 and three quarters within 58. This study's planned 20 months is below that.

Counting every sponsor, half of 355 studies reached it within 34 months; a quarter within 15 and three quarters within 57.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 3, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
