“…Cell death and injury due to inflammation may cause structural and functional cardiac abnormalities presenting with various clinical manifestations. Because acute myocarditis may mimic ST-segment elevation myocardial infarction (STEMI), its early identification may have important therapeutic and prognostic implications [ 2 , 3 ]. Coronary artery spasm is a sudden, intense, transient and reversible vasoconstriction of an epicardial coronary artery that can also result in ST-segment elevation.…”

Background Myocarditis refers to the inflammation of the myocardium caused by infection or autoimmune disease that may or may not present with clinical manifestations, such as gastrointestinal symptoms, dyspnea, chest pain, or sudden death. Although myocarditis and coronary artery vasospasm may mimic ST-segment elevation myocardial infarction (STEMI) with normal coronary arteries on angiography, acute myocarditis rarely causes coronary artery spasm. Here, we report a case of coronary artery spasm with reversible electrocardiographic changes mimicking STEMI in an adolescent with acute myocarditis. Case presentation A 15-year-old boy present with sudden-onset repeated chest pain following a 3-day history of flu-like illness. Cardiac biomarkers were significantly elevated. Electrocardiography showed ST-segment elevation in the absence of detectable vasospasm on coronary angiography. These findings were consistent with the diagnosis of coronary artery spasm secondary to acute myocarditis. Treatment with immunoglobulin for 2 days improved his condition. The patient was discharged on the 12th day with complete resolution of symptoms and normalization of electrocardiogram findings. Conclusions We reported a case of coronary artery spasm due to acute myocarditis. This study highlights the importance of considering coronary artery spasm due to acute myocarditis as a differential diagnosis in patients presenting with signs of STEMI as these diseases have different medical management strategies.

“…It can present with various clinical manifestations and may mimic myocardial infarction (MI), since patients usually present with chest pain, and the electrocardiographic changes similar to those observed in acute ST-elevation MI. [2][3][4] In this report, we present such an extreme case of acute myocarditis characterized by dynamic ST segment elevation with reciprocal changes in the electrocardiogram (ECG).…”

a b s t r a c tAcute myocarditis is a well-recognized but rare manifestation of mostly viral infections. It can present with various clinical manifestations and may mimic myocardial infarction (MI) since patients usually present with chest pain, and the electrocardiographic changes similar to those observed in acute ST-elevation MI. We, herein, present such an extreme case of acute myocarditis characterized by dynamic ST segment elevation with reciprocal changes in the electrocardiogram.
