About this study
The goal of this observational study is to learn about the Prevalence, Clinical Features, and Prognosis of Coronary Artery Embolism With Concomitant Atrial Fibrillation. The main question it aims to answer is:
What is the proportion of coronary artery embolism with concomitant atrial fibrillation among all myocardial infarctions and myocardial infarctions with concomitant atrial fibrillation? What are the clinical characteristics of coronary artery embolism with concomitant atrial fibrillation? What is the prognosis of coronary artery embolism with concomitant atrial fibrillation? All participants will receive routine diagnosis and treatment, and baseline demographic data, clinical examination laboratory results, and follow-up data will be collected for analysis.
Read the detailed description
The study is designed as an observational study without involving experimental drugs or device interventions, only collecting data from routine medical practice.
Importance: Atrial fibrillation (AF) and acute myocardial infarction (AMI) share common risk factors and interact pathophysiologically. Coronary embolism (CE) is a critical mechanism of AMI in AF patients, yet its clinical features and prognosis remain understudied.
Objective: To investigate the incidence, clinical characteristics, and prognosis of CE in patients with AF.
Design, Setting, and Participants: A single-center retrospective case-control study was conducted at the Affiliated First Hospital of Ningbo University, China. Patients diagnosed with AMI who underwent coronary angiography (CAG) between January 1, 2014, and December 31, 2023, were included. CE was diagnosed using the Shibata criteria. Participants were categorized into three groups: AF-related CE, non-CE AF with AMI, and AMI without AF.
Main Outcomes and Measures: Baseline characteristics, clinical features, coronary involvement, treatment strategies, and outcomes (all-cause mortality, cardiac-death mortality, major adverse cardiovascular and cerebrovascular events [MACCE], recurrent embolism, and major bleeding) were compared.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Is it coronary artery embolismOther
This observational study categorizes patients with acute myocardial infarction (AMI) into three distinct groups based on their clinical characteristics:
- Group 1: Patients with atrial fibrillation (AF) and coronary artery embolism (CAE).
- Group 2: Patients with AF but non-coronary artery embolism myocardial infarction (non-CAE MI).
- Group 3: Patients without AF and non-coronary artery embolism myocardial infarction (non-CAE MI without AF).
A key innovation of this study compared to previous research is its expanded eligibility criteria for AMI patients. Earlier studies typically focused exclusively on ST-segment elevation myocardial infarction (STEMI). In contrast, this investigation encompasses a broader spectrum of acute myocardial infarction, including both STEMI and non-ST-segment elevation myocardial infarction (NSTEMI). This comprehensive approach enhances the generalizability and applicability of the findings by capturing a wider range of clinical scenarios.

What are the clinical characteristics of coronary artery embolism with concomitant atrial fibrillation? What is the prognosis of coronary artery embolism with concomitant atrial fibrillation? All participants will receive routine diagnosis and treatment, and baseline demographic data, clinical examination laboratory results, and follow-up data will be collected for analysis.

Questions about this trial
What is this clinical trial studying?
An observational study of Coronary Artery Embolism and Acute Myocardial Infarction Type 2, run by First Affiliated Hospital of Ningbo University at 2 sites in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 10 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 25 Feb 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 2 sites 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.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
All-cause death, cardiogenic death (time frame: Up to 10 years). The study lists 4 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT06845956, which also lists 10 linked publications.
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?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 25 Feb 2025; AzTrials last refreshed its copy on 8 Nov 2026.
