Mechanisms of Stress (Takotsubo) Cardiomyopathy Sebastian Szardien, Helge Mollmann, Matthias Willmer, Yoshihiro J. Akashi, Christian W. Hamm, and Holger M. Nef Stress cardiomyopathy is a form of reversible systolic dysfunction of the mid and apical left ventricle with pathologic changes of the electrocardiogram in the absence of an obstructive coronary artery disease. The prevalence of stress cardiomyopathy among patients with symptoms. suggestive of myocardial infarction is 0.7% to 2.5%, and it is found predominantly in postmenopausal women (90%). No large studies have confirmed the cause of stress cardiomyopathy. Published data suggest that substantially elevated plasma catecholamine levels, due to emotional or physical stress, may be relevant.
