Abstract

Takotsubo cardiomyopathy is an acute cardiac entity with clinical manifestations similar to myocardial infarction, accounting for 1-2% of acute coronary syndrome admissions. Its underlying pathophysiology is not yet well established. It is usually associated with acute physical or emotional stress, but the list of potential triggers has grown as the condition attracts the attention of the medical community. In order to diagnose the condition correctly and to gain new insights into it, we need to know its potential triggers as well as its clinical presentation and diagnostic criteria. We report a case of takotsubo cardiomyopathy triggered by hyponatremia.

Resumo

A cardiomiopatia de Takotsubo é uma entidade nosológica que se caracteriza por manifestações clínicas similares às do enfarte agudo do miocárdio, representando cerca de 1-2% de todos os doentes admitidos por síndrome coronária aguda. A sua etiopatogenia ainda não está totalmente esclarecida. Geralmente, está associada a vigorosos estímulos físicos ou emocionais. Com o crescente reconhecimento desta entidade, a lista de potenciais estímulos despoletadores tem crescido nos últimos anos. O conhecimento destes novos estímulos permitirá não só um diagnóstico correcto mas também o aprofundamento dos seus mecanismos fisiopatológicos. Os autores descrevem um caso de cardiomiopatia de Takotsubo induzida por hiponatremia.
