Hyponatremia – an unusual trigger of Takotsubo cardiomyopathy

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,...
