Takotsubo syndrome (TTS) is an emerging disease characterized by an acute and reversible myocardial dysfunction which may have an influence on clinical status and prognosis. Despite extensive research, its pathophysiology has not been completely elucidated; among other hypothesis, a heart-brain interaction has been proposed.
The aim of this study was to assess the impact of psychiatric disorders and of some personality types on the pathogenesis of TTS. We conducted a retrospective observational case-control study. We enrolled a total of 50 patients, 25 with a previous diagnosis of TTS and 25 patients with a history of acute coronary syndrome (ACS), that underwent a comprehensive lifetime psychiatric assessment.
We found no significant difference between TTS and ACS patients in cardiovascular risk profile. The frequency of lifetime psychiatric disorders was significantly greater in TTS. In particular, in the univariate analysis, TTS group showed a higher prevalence of mood disorders (Major Depressive Disorder, Bipolar Disorder, Dysthymia; 16 vs. 2,
Our study demonstrated that pre-existing anxiety disorders and mostly mood disorders were significantly higher in TTS patients than in ACS group, suggesting the role of psychiatric disorders as possible pathophysiological substrate of TTS.
