Аннотация
PURPOSE: Takotsubo cardiomyopathy (TC) is described as transient ventricular dysfunction following emotional or physical trauma. A few reports have described patients with TC in association with various circumstances of thyrotoxicosis. We report an unusual case of TC in a patient with a large retrosternal goiter and normal thyroid function. We speculate that TC was triggered by compromise of tracheal flow induced by the goiter.
CLINICAL FEATURE: A 68-yr-old woman without primary heart disease presented with cardiorespiratory collapse requiring ventilatory and cardiovascular support, including placement of an intra-aortic balloon pump. She was diagnosed with a severe form of TC based on characteristic echocardiography findings and clinical course. Within less than a week, her myocardial function completely normalized. The patient was later found to have a large retrosternal goiter compressing her trachea, though her thyroid function was normal. A total thyroidectomy was eventually performed, and she made a full recovery. Subsequently, the patient was found to have a positive JAK2 mutation for a myeloproliferative disorder.
CONCLUSIONS: Takotsubo cardiomyopathy may be regarded as the final common pathway of cardiac dysfunction triggered by various stress conditions, in this case, a large retrosternal goiter not associated with thyrotoxicosis and likely exacerbated by severe leukocytosis related to a myeloproliferative disorder.
