Stress-Induced Cardiomyopathy Masquerading as Acute ST-Segment Elevation Myocardial Infarction.

Myocardial stress can lead to a myriad of cardiovascular complications, and stress-induced cardiomyopathy is the predominant manifestation. Exogenous or endogenous hormonal excess, sepsis, tachycardia, and physical or emotional trauma can lead to neurohormonal and catecholaminergic surges. Stress-induced cardiomyopathy often presents with chest pain, ischemic-like ECG changes, troponin elevation, and wall motion abnormalities in echocardiography. It is a diagnosis of exclusion, and coronary artery disease needs to be ruled out by a normal angiogram as per guidelines. It presents predominantly in postmenopausal women and presentation is similar to acute coronary syndrome (ACS) due to plaque rupture. We report a case of a 72-year-old female who presented to the emergency room with severe anginal chest pain without any preceding stress. ECG showed lateral leads ST-elevation and serial serum troponins were elevated. Emergent cardiac catheterization showed insignificant coronary artery disease. Left ventriculogram and echocardiogram showed a moderately reduced left ventricular systolic function with akinetic-hypokinetic mid to distal myocardial segments and normal basal contraction suggestive of stress-induced cardiomyopathy.
