Description of a Patient Suspected of Myocardial Infarction With Normal Coronary Artery: A Case Report of Takotsubo Cardiomyopathy

Abstract

Takotsubo cardiomyopathy (TC) is characterized by transient systolic dysfunction, presenting with electrocardiographic (ECG) changes and mimicking acute coronary syndrome (ACS). Studies have shown that 95% of patients have changes in ECG. ECG changes in TC syndrome may be similar to myocardial infarction )MI(. ECG changes can be seen in the form of ST-segment elevation or deep T-wave inversion. TC can be considered a special form of ACS. TC is not a benign entity, and conduction abnormalities can occur. The acute phase can be predicted based on decreased EF and arrhythmia. Different treatments are used in the acute phase of TC, depending on the hemodynamic condition. Our case elucidates the importance of age, female gender, symptoms, such as stress and emotion, clinical manifestations, ECG characteristics, and echocardiography in TC. This paper describes a case of TC from a hospital affiliated to Rafsanjan University of Medical Sciences. The case was a 75-year-old woman with no history of cardiovascular diseases who has been admitted to the hospital with myocardial infarction.
