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 signifi cant 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.

Hypereosinophilic syndrome (HES) is a rare disorder of unregulated eosinophilia, which if untreated, may lead to systemic tissue infiltration and inflammation. Cardiac involvement is a common and serious associated complication. We describe a case of HES associated myocarditis mimicking a non-ST elevation MI (NSTEMI). Unlike myocarditis in general, our patient responded well to high dose methylprednisone, the standard of care in HES. We review the clinical presentation, pathophysiology, pathology and treatment of eosinophilic myocarditis related to HES.
