Brugada phenocopy in a patient with acute myocardial infarction

Abstract

Introduction: Brugada phenocopy is a medical condition that presents with an electrocardiographic pattern identical to Brugada syndrome, but is caused by various reversible external factors rather than genetic abnormalities.

Objective: To present a clinical case linking the presence of a Brugada electrocardiographic pattern with ST-segment elevation myocardial infarction.

Case Presentation: An 80-year-old patient presented with symptoms of chest pain and was diagnosed with acute myocardial infarction with ST-segment elevation. He progressed to cardiogenic shock, and an electrocardiogram revealed a Brugada type 1 pattern. Percutaneous transluminal angioplasty of the left anterior descending artery was performed, and coronary flow was successfully restored.

Conclusions: Brugada phenocopy is an uncommon condition nowadays; its presentation in the course of an acute myocardial infarction is even more unusual. The correction of the underlying cause and the influence of each patient's personal history influence their prognosis.
