N2 - PURPOSE: To compare the ability of delayed-enhancement magnetic resonance imaging (DE-MRI) and other MRI and clinical parameters to identify diseases mimicking stress cardiomyopathy (SCM).MATERIALS AND METHODS: The study included 14 consecutive patients fulfilling the American Heart Association (AHA) criteria for SCM with acute left ventricular dysfunction in the absence of coronary artery disease, triggered by psychological stress. The MRI protocol consisted of cine, T 2-weighted, first-pass-perfusion (FPP) and DE-MRI.RESULTS: Six patients with DE were classified as mimicking SCM (non-SCM) and 8 patients without DE as SCM. FPP defects were found in 4 patients with non-SCM and in none with SCM (p < 0.05). Myocardial edema was found in 5 patients with non-SCM and in 2 patients with SCM (p = ns). No significant differences in clinical findings such as ECG, cardiac markers and echocardiographic recovery of left ventricular function were found between patients with non-SCM and SCM.CONCLUSION: Non-SCM defined by DE-MRI is a frequent finding in patients fulfilling the AHA criteria for SCM. Clinical findings seem to be of limited value to differentiate between non-SCM and SCM.
