abstract={Stress cardiomyopathy is characterized by reversible wall motion abnormalities and transient systolic dysfunction in the absence of obstructive CAD or acute plaque rupture. Majority of cases involve intense emotional or physical stress triggers in post-menopausal women. Catecholamine surge, one postulated mechanism, causes acute but completely reversible myocardial dysfunction. MRI can be associated with significant stress, particularly in claustrophobic people. Our patient, with no cardiac or psychiatric history, demonstrated a stressful response to MRI developing Takotsubo cardiomyopathy (TCM) both times after the MRI in 2009 and 2013. Her anxiety likely provoked the TCM. Coronary angiography showed no obstructive disease and echocardiography showed wall motion abnormalities and systolic dysfunction, with full recovery each time confirmed on repeat echo. Patient was managed with conservative medical therapy both times. A thorough literature search failed to reveal any previously reported cases of recurrent cardiomyopathy precipitated by anxiety from MRI scan. Judicious use of anxiolytics may have averted a stressful response in our patient, perhaps preventing the development of TCM.},
