Summary

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.

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.

Conditions

• Coronary Artery Embolism
• Acute Myocardial Infarction Type 2

Interventions

Type	Name	Description
OTHER	Is it coronary artery embolism	This observational study categorizes patients with acute myocardial infarction (AMI) into three distinct groups based on their clinical characteristics: 1. Group 1: Patients with atrial fibrillation (AF) and coronary artery embolism (CAE). 2. Group 2: Patients with AF but non-coronary artery embolism myocardial infarction (non-CAE MI). 3. 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.
