Takotsubo cardiomyopathy (TCMP) is a cardiac disorder, often seen in post-menopausal women, that resembles an acute coronary syndrome in its clinical presentation. The aetiopathogenesis of TCMP may have an endocrine basis, and hence we believe the term 'takotsubo endocrinopathy' may be more appropriate. In this review, we describe the various endocrine disorders that may lead to TCMP. We also describe the pathogenetic mechanism by which these endocrine disorders may lead to TCMP. Cardiomyopathy associated with pheochromocytoma closely resembles TCMP and we have suggested that it must be ruled out in all patients presenting with TCMP. The role of oestrogen deficiency in the pathogenesis of TCMP is examined in this article. The importance of the involvement of an endocrinologist in the management of TCMP is emphasised.
