BERTI, Marco et al. Electrocardiographic pattern combined with echocardiographic wall motion abnormalities in stress related cardiomyopathies: clinical and pathophysiological insights. Arch. Cardiol. Méx. [online]. 2012, vol.82, n.1, pp.22-30. ISSN 1665-1731.

We report five cases of stress related cardiomyopahies that occurred in post-menopausal women (age range from 49 to 90) consecutively admitted to our Department in the last year in different clinical settings: typical anginal pain, carotid endarterectomy, pulmonary edema, cardiogenic shock, and severe asthenia. Apical left ventricular involvement was observed in three patients in conjunction with ECG mild ST segment elevation in anterior precordial leads resembling acute anterior myocardial infarction; isolated mid ventricular dysfunction was present in two patients in conjunction with ST segment depression in the anterior precordial leads. The ECG evolved showing T wave inversion in four cases and normalized in one. In all cases, blood chemistry showed mild elevation of CK-MB and TN. The observed wall motion abnormalities were reversible in four of five cases during hospital stay. Stress echocardiography was performed in two patients (dobutamine in the patient with persistent mid-ventricular hypokinesis, exercise in another case) and correctly predicted the absence of coronary artery disease. We conclude that wall motion analysis at echocardiography combined with ECG ST segment changes and serum markers of myocardial necrosis (CK-MB and TN) may allow recognition of stress cardiomyopathies in different clinical settings. Echo stress may be proposed in those patients in whom some suspicion of coronary artery disease persists.
