Resumen

IRIGARAY ECHARRI, A et al. Takotsubo syndrome and hyperthyroidism: a case report. Anales Sis San Navarra [online]. 2019, vol.42, n.2, pp.215-220.  Epub 02-Mar-2020. ISSN 1137-6627.  http://dx.doi.org/10.23938/assn.0713.

Stress cardiomyopathy, or Takotsubo syndrome, is similar to that of an acute coronary syndrome, with electrocardiographic changes and an increase in troponin levels; however, coronary arteriography typically shows no obstructive lesions. One of the characteristic patterns are regional wall motion abnormalities identified by echocardiography. It has been described in association with thyroid disorders, although the causal mechanism is not clearly established.

We present the case of a woman with acute chest pain and electrical and analytical changes. A severe ventricular dysfunction was observed but the coronary tree was free of lesions, all of which was compatible with a stress cardiomyopathy. Hyperthyroidism due to Graves’ disease was observed as a trigger.

The identification and management of clinical factors that might predispose patients to Takotsubo syndrome or impact on subsequent clinical outcome is mandatory.

Palabras clave : Hyperthyroidism; Cardiomyopathy; Takotsubo syndrome; Thyroid diseases; Graves’ disease.
