Stress cardiomyopathy following thyroidectomy in a postmenopausal patient: A case report.

Introduction And Importance: First described in 1990 in Japan, Stress cardiomyopathy (SC) 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. SC is an increasingly recognized form of transient LV dysfunction that is often completely reversible.

Case Presentation: We report a case of SC induced by thyroidectomy in a postmenopausal woman with a good outcome for the patient.

Clinical Discussion: 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. It is described as a disease with a 6-fold female-male predominance, affecting elderly postmenopausal women leading researchers to an estrogen-based theory for the pathogenesis. Thera are also increasing evidences for link between SC and thyroid pathology. There is no consensus on the diagnostic criteria for SC.

Conclusion: SC should be kept in mind especially in women with postmenopausal syndrome in perioperative period.
