title: Atypical stress-induced cardiomyopathy: a case series.
abstract: Stress-induced cardiomyopathy (SIC) is characterized by reversible left ventricular (LV) systolic dysfunction, which appears to be triggered by an intense, stressful event in the absence of significant coronary artery disease. It manifests typically with transient left ventricular wall motion abnormalities (WMA) involving the apical and/or mid-ventricular myocardial segments, associated with minimal troponin rise (<5 ng/ml), and typical EGG changes. Described are 3 cases of stress-induced cardiomyopathy with atypical distribution of wall motion abnormalities. Possible contributing mechanisms to the pathogenesis and the variability in WMA are discussed.
