Various medical conditions, including Takotsubo cardiomyopathy, coronary vasospasm, and myopericarditis, can present as ST-segment elevation myocardial infarction mimickers.
Highlights critical mimickers of ST-segment elevation myocardial infarction, indicating the need to distinguish true acute coronary syndromes from non-infarction etiologies.
A rapid diagnosis of ST-segment elevation myocardial infarction (STEMI) is mandatory for optimal treatment of an acute coronary syndrome. However, a small number of patients with suspected STEMI are afflicted with other medical conditions. These medical conditions are rare, but important clinical entities that should be considered when evaluating a STEMI alert. These conditions include coronary vasospasm, Takotsubo cardiomyopathy, coronary arteritis/aneurysm, myopericarditis, Brugada syndrome, left bundle branch block, early repolarization, aortic dissection, infective endocarditis with root abscess, subarachnoid hemorrhage, ventricular aneurysm after transmural myocardial infarction, and hemodynamically significant pulmonary embolism with right ventricular strain. Herein, we present several STEMI mimickers.

Patel et al. (2016) conducted a review in Suspected ST-segment elevation myocardial infarction (STEMI). Conditions mimicking STEMI was evaluated. Various medical conditions, including Takotsubo cardiomyopathy, coronary vasospasm, and myopericarditis, can present as ST-segment elevation myocardial infarction mimickers.
