To the Editor: The study by Dr Eitel and colleagues1 attempted to identify cardiac magnetic resonance (CMR) imaging criteria for accurate diagnosis of stress cardiomyopathy (SC). The data on this phenomena thus far have been sparse and heterogeneous. However, a few points require clarification.
The authors used the proposed Mayo criteria for diagnosis of SC,2 which include absence of obstructive coronary disease or evidence of acute plaque rupture. However, they included 16 patients with more than 75% occlusion of epicardial coronary arteries, albeit not in an area of wall motion abnormality. It would be interesting to know the rationale behind inclusion of these patients, who may have been misclassified as having SC.
