Background: In recent times, the connections between mental health and cardiac outcomes have been under increasing investigation. Tako-Tsubo Cardiomyopathy (TTC) is also called “broken heart syndrome”, since it has been described to occur after emotionally stressful events; it presents as an acute reversible coronary syndrome due to a transient failure of the left ventricle, in the absence of obstructive coronary heart disease. It has a 10-timehigher prevalence in postmenopausal women and may have a strong correlation with biopsycho- social stress. Aim: To review existing studies on TTC in comorbidity with psychiatric disorders. Method: Four PubMed literature searches performed during January 2015 (search terms: tako-tsubo AND psy*; tako-tsubo AND anxiety; tako-tsubo AND depression; tako-tsubo AND mania) provided 9 references: 4 case reports, 2 reviews, 2 prospective studies and 1 case–control study. Results: Not only chronic psychological stress (present in 2/3 of these patients, on average), but also a high co-occurrence of anxiety and depression (from 50 to 70% of patients with this cardiopathy), panic attacks (diagnosed in almost 20% of women with tako-tsubo), subthreshold and full-blown PTSD (co-morbid in almost 40% of patients according to a 2-year prospective study) were associated with TTC. It has been suggested that changes in circulating levels of catecholamines combined to heart's abnormal response to these hormones could be at the pathophysiological basis for such associations. Conclusion: The present literature review confirms a high cooccurrence of comorbid conditions with increased sympathetic activity (in particular anxiety, depression and panic disorder), which could be risk factors for TTC. More studies, especially longitudinal ones, are needed to better clarify the causative pathways of this usually reversible, but potentially lethal, syndrome, especially among post-menopausal women.
