Key result
Treatment with colchicine and steroid led to the resolution of symptoms and EKG changes in a patient with regional pericarditis mimicking an acute anterolateral STEMI.
Why the study?
Acute pericarditis often mimics ACS, and the rare form of regional pericarditis can present on EKG as an acute STEMI of a particular wall, requiring differentiation due to different treatments.
Case Report (n=1)
Regional pericarditis can present with localized ST-segment elevation mimicking acute myocardial infarction, highlighting the importance of accurate diagnosis to guide appropriate therapy.

Regional pericarditis should be considered in STEMI mimics; this case leaves open the efficacy of colchicine-steroid therapy.
Acute pericarditis is common and often mimics acute coronary syndrome (ACS) in clinical as well as electrographic presentation. It is essential to differentiate between these two conditions, as treatment is different. A rare form of acute pericarditis, regional pericarditis, can be elusive, especially when it presents on EKG as an acute ST-segment elevation MI of a particular wall. We present a case of localized (regional) pericarditis in a 66-year-old female with a history of rheumatoid arthritis who presented to the emergency department with localized left-sided chest pain. Her arrival EKG showed acute anterolateral wall ST-segment elevation. The patient received diagnostic cardiac catheterization, treatment with colchicine and steroid, which produced resolution of symptoms and EKG changes.

Malik et al. (2020) conducted a case report in Regional pericarditis mimicking ST-segment elevation myocardial infarction (n=1). Colchicine and steroid was evaluated on Resolution of symptoms and EKG changes. Treatment with colchicine and steroid led to the resolution of symptoms and EKG changes in a patient with regional pericarditis mimicking an acute anterolateral STEMI.
