Prevalence, Clinical Features, and Prognosis of Coronary Artery Embolism With Concomitant Atrial Fibrillation

"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."
