Stress cardiomyopathy (SC) is a poorly recognized heart disease that was initially regarded as a benign condition. Recently, it has been shown that SC may be associated with severe clinical complications including death and that its prevalence is probably underestimated. The disease is characterized by transient systolic and diastolic left ventricular (LV) dysfunction with a variety of wall-motion abnormalities. It predominantly affects postmenopausal women and is often preceded by an emotional or physical trigger, but the condition has also been reported with no evident trigger. The striking preponderance of postmenopausal females suggests a hormonal influence. Potentially, declining oestrogen levels after menopause increase the susceptibility to SC in women. Oestrogens can influence vasomotor tone via up-regulation of endothelial NO synthase. Also, there is evidence that oestrogens can attenuate catecholamine-mediated vasoconstriction and decrease the sympathetic response to mental stress in perimenopausal women. Rare cases of SC following thyroidectomy in premenopausal women have been described. Currently, the pathogenesis of SC remains obscure, several possible hypotheses include catecholamine induced myocardial spasm or catecholamine related myocardial stunning, metabolic disorders and coronary microvascular damage. So prompt diagnosis and optimal management are crucial to obtaining a good outcome for the patient. We report an extremely rare case of SC induced by thyroidectomy in a premenopausal woman with cancer, and share our personal experience by reviewing the literature.
