Brief 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.
