Troponins in Tako-tsubo Cardiomyopathy

Tako-tsubo cardiomyopathy was first described in Japan in 1990. The clinical presentation of Tako-tsubo cardiomyopathy (TCM) is similar to an acute myocardial infarction with patients having chest pain, ST segment elevations on EKG and elevated cardiac biomarkers. In TCM, however, the elevation in cardiac enzymes is usually mild. We report a case of TCM where the patient had Troponin I elevation up to 42.3 ng/ml. To the best of our knowledge, this is the first case in which such high troponins have been reported in a patient with Tako-tsubo cardiomyopathy.
