Context:
Catecholamine-related factors are the most popular explanation for the occurrence of Takotsubo syndrome. An aldosterone-related mechanism, however, has not been proposed.
Case Description:
A 45-year-old male patient presenting with ST-segment elevation myocardial infarction was diagnosed with primary aldosteronism, severe hypokalemia, and Takotsubo syndrome. After excluding the known conditions of apical ballooning and the factors of vasospasm, primary aldosteronism is considered as the major contributor to the development of Takotsubo syndrome. The potential mechanisms are discussed.
Conclusions:
The case suggests a possible hyperaldosteronism-induced and vasoconstriction-mediated mechanism in the development of Takotsubo syndrome.
