AbstractAcute myocardial infarction (MI) is a common and severe cardiovascular emergency that requires immediate treatment. Angina pectoris, which typically signals myocardial ischaemia, can appear in MI cases with myriad causes aside from coronary artery disease. However, not all MI patients benefit from invasive revascularisation therapy. We herein report a case involving a 78-year-old female patient with a complex medical history, including non-ST-segment elevation MI and coronary artery bypass grafting, who experienced recurrent chest pain. Instead of a direct result of coronary artery disease, her chest pain was later found to be primarily induced by atrial fibrillation (AF). Consequently, we shifted the focus of management to effective rate control for the AF after careful evaluation and achieved a satisfactory result. This case highlights the successful identification and timely application of intensive heart rate control management in an MI case induced by AF.Copyright © 2024 The Authors.
