Takotsubo syndrome: more frequent in women, more dangerous in men.

Abstract

Takotsubo syndrome (TTS) is an acute myocardial disease characterized by reversible left ventricular dysfunction, in the absence of obstructive coronary artery disease, caused by adrenergic overactivity and associated with non-negligible morbidity and mortality. Takotsubo syndrome, by far more frequent in women, who account for 9 out of 10 cases, is generally triggered by intense psychoemotional stress. In men, TTS has different, though not yet fully defined, characteristics and clinical course. In fact, men have a higher prevalence of a physical trigger and comorbidities, such as bronchopulmonary or cerebral pathologies, diabetes mellitus, and malignant neoplasms. The hospital course is burdened by a higher rate of cardiogenic shock and mortality. The long-term prognosis is also less favourable in men. Takotsubo syndrome in men characterizes a higher-risk phenotype, which requires close monitoring during hospitalization and careful surveillance during follow-up.
