Abstract
Acute coronary syndrome (ACS) is a term used to describe a spectrum of diseases associated with sudden reduced blood flow to the heart. Coronary artery thromboembolism is recognized as an important nonatherosclerotic cause of acute myocardial infarctions in 2.9% of ACS cases, with a long-term outcome indicating that coronary embolism patients represent a high-risk subpopulation. There are various risk factors for developing a coronary thromboembolism, with atrial fibrillation being the most frequently reported cause. Herein, we are presenting a case of a 65-year-old female patient who presented to the emergency department with sudden-onset pressure-like chest pain diagnosed as ACS due to nonatherosclerotic thromboembolism secondary to atrial flutter.
