Elevated levels of thyroid hormones cause exaggerated inotropic and chronotropic responses to catecholamines.

It may be related to sex differences in myocardial sensitivity to catecholamines and the potentially important role of estrogens in the pathogenesis of this entity [ 1 — 48 ].

There are several hypotheses that may explain the relationship between TM and thyroid diseases.
Tokyo: Kagakuhyouronsya Co. Background: Takotsubo cardiomyopathy TMalso called stress myocardiopathy or transient left ventricular apical ballooning syndrome, is characterized by acute left ventricular dysfunction with reversible wall motion abnormalities. Several pathophysiological mechanisms have been proposed in TM: spasm of multiple epicardial vessels, deterioration of the coronary microvasculature, and microvascular spasm resulting in myocardial stunning [ 3 ].
Thyrotropin receptor antibodies TRAb were positive, and the thyroid echography showed mild enlargement of the thyroid gland, without nodules. Conclusions: Our case illustrates that thyroid disease, mainly hyperthyroidism, should be considered in patients with TM with or without previous emotional triggers.
