A Case of Acute Myopericarditis with Localized ST Elevation Mimicking Myocardial Infarction / 대한내과학회지

ABSTRACT

Although, with regard to diagnosis, history, physical examination, laboratory data, and electrocardiogram (ECG) are helpful, it can be difficult to distinguish between pericarditis, myopericarditis, and myocardial infarction. Typically, the ECG pattern evolves similarly in acute pericarditis and myopericarditis and includes diffuse ST elevation and PR depression, and then diffuse T wave inversion. Nevertheless, atypical ECG features are seen occasionally in both, especially in myopericarditis. They are characterized by localized ST elevation (inferolateral or anterolateral) and T wave inversion before ST segment normalization. This makes it difficult to distinguish acute myopericarditis from acute myocardial infarction. We report the case of a 27-year-old man with acute myopericarditis with localized ST elevation mimicking acute myocardial infarction.
