Study population: This study is an ambispective, registry-based cohort study that includes patients diagnosed with acute myocardial infarction who underwent primary percutaneous coronary intervention (PCI) at Zhongshan Hospital, Fudan University, from January 1, 2009, to December 31, 2028.

Who may be able to join

  • Hospitalized at Zhongshan Hospital, Fudan University, with a diagnosis of acute myocardial infarction (AMI) according to the Universal Definition of Myocardial Infarction, between January 1, 2009, and December 31, 2028.
  • Underwent primary percutaneous coronary intervention (PCI) during hospitalization (within 12 hours of symptom onset, or beyond 12 hours with persistent evidence of ischemia).

About this study

Official title: Trends and Risk Factors of Major Adverse Cardiovascular and Cerebrovascular Events After Primay Percutaneous Coronary Intervention in Acute Myocardial Infarction: A Long-Term Follow-Up Study Based on Hospital Real-World Data

This single-center, ambispective cohort study will use real-world data from Zhongshan Hospital, Fudan University. About 8,000 patients aged 18 years or older with acute myocardial infarction (AMI) who underwent primary percutaneous coronary intervention (PCI) from 2009 to 2028 will be included. Patients will be grouped into four periods: 2009-2013, 2014-2018, 2019-2023, and 2024-2028. The study aims to describe 20-year trends in in-hospital events and major adverse cardiovascular and cerebrovascular events (MACCE) within 2 years after PCI and to identify independent risk factors. The primary outcome is MACCE within 2 years, defined as a composite of all-cause death, recurrent myocardial infarction, ischemia-driven repeat revascularization, and non-fatal ischemic stroke. Key secondary outcomes include in-hospital all-cause death, impaired myocardial perfusion, malignant arrhythmia, acute heart failure, recurrent myocardial infarction, non-fatal ischemic stroke, and bleeding events. Data will come from electronic medical records and the cardiac catheterization database.

Read the detailed description

Background: Acute myocardial infarction (AMI) is a leading cause of cardiovascular death in China. Primary PCI improves outcomes, but patients remain at risk of in-hospital events and long-term major adverse cardiovascular and cerebrovascular events (MACCE). Long-term real-world evidence from China is limited.

Design: This single-center, ambispective cohort study will include about 8,000 AMI patients aged 18 years or older treated with primary PCI at Zhongshan Hospital, Fudan University, from 2009 to 2028. Patients will be divided into four periods: 2009-2013, 2014-2018, 2019-2023, and 2024-2028. Follow-up will be 2 years after PCI or until an endpoint event, death, or loss to follow-up.

Objectives: To describe the incidence and 20-year trends of in-hospital events and 2-year MACCE, and to identify independent risk factors.

Outcomes: The primary outcome is 2-year MACCE, defined as a composite of all-cause death, recurrent myocardial infarction, ischemia-driven repeat revascularization, and non-fatal ischemic stroke. The key secondary outcome is in-hospital all-cause death. Other secondary outcomes include impaired myocardial perfusion, malignant arrhythmia, acute heart failure, recurrent myocardial infarction, non-fatal ischemic stroke, and bleeding events.

Data and Analysis: Data will be obtained from electronic medical records and the cardiac catheterization database. Retrospective data will be collected for 2009-2026, with prospective enrollment for 2027-2028. Descriptive analysis, Kaplan-Meier method, log-rank test, Cox proportional hazards models, and logistic regression will be used. Subgroup and sensitivity analyses will be performed.

Ethics: Ethical approval will be obtained from the Ethics Committee of Zhongshan Hospital, Fudan University. Written informed consent will be obtained from prospective patients; verbal consent or a waiver will be requested for retrospective patients. No study-specific interventions are involved in this observational study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Major Adverse Cardiovascular and Cerebrovascular Events (MACCE)

    Composite of all-cause death, recurrent myocardial infarction, ischemia-driven repeat revascularization, and non-fatal ischemic stroke. The first occurrence of any component will be used for time-to-event analysis.

    Measured: Within 2 years after PCI

Secondary outcomes (11)
  1. In-hospital all-cause death

    Death from any cause during hospitalization.

    Measured: Perioperative/Periprocedural

  2. In-hospital impaired myocardial perfusion

    Post-PCI TIMI flow grade <3 in the infarct-related artery.

    Measured: At the end of the PCI procedure

  3. In-hospital malignant arrhythmia

    New-onset ventricular tachycardia, ventricular fibrillation, or other malignant arrhythmias requiring drug therapy, electrical cardioversion/defibrillation, or temporary pacing during hospitalization.

    Measured: Perioperative/Periprocedural

  4. In-hospital acute heart failure

    New-onset or worsening acute heart failure requiring intravenous diuretics, vasoactive drugs, or mechanical support (e.g., IABP, ECMO).

    Measured: Perioperative/Periprocedural

  5. In-hospital recurrent myocardial infarction

    Recurrent myocardial infarction during hospitalization.

    Measured: Perioperative/Periprocedural

  6. In-hospital non-fatal ischemic stroke

    Non-fatal ischemic stroke during hospitalization.

    Measured: Perioperative/Periprocedural

  7. All-cause death within 2 years after PCI

    Death from any cause within 2 years after PCI.

    Measured: Within 2 years after PCI

  8. Cardiovascular death within 2 years after PCI

    Death from cardiovascular causes within 2 years after PCI. Cardiovascular death includes death due to myocardial infarction, heart failure, arrhythmia, stroke, or other cardiovascular causes.

    Measured: Within 2 years after PCI

  9. Recurrent myocardial infarction within 2 years after PCI

    Recurrent myocardial infarction within 2 years after PCI.

    Measured: Within 2 years after PCI

  10. Ischemia-driven repeat revascularization within 2 years after PCI

    Repeat PCI or CABG driven by ischemia within 2 years after the index PCI.

    Measured: Within 2 years after PCI

  11. Non-fatal ischemic stroke within 2 years after PCI

    Non-fatal ischemic stroke within 2 years after PCI.

    Measured: Within 2 years after PCI

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Chunfeng Dai, M.D. (86-021-64041990, dai.chunfeng@zs-hospital.sh.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Major Adverse Cardiovascular and Cerebrovascular Events (MACCE) (time frame: Within 2 years after PCI). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?
