Background: Takotsubo syndrome (TTS) is an acute heart syndrome characterised by reversible ventricular dysfunction with the absence of significant coronary occlusion, which typically occurs in postmenopausal women after emotional or physical stress. Differences of clinical or instrumental characteristics between fertile women and postmenopausal women with TTS have not yet been studied. The aim of this study was to investigate the differences in clinical, biochemical and echocardiographic characteristics between postmenopausal women and fertile women with TTS.Methods: One hundred and thirty-one patients (mean age 67.8 ± 11.3 years; 14 patients were still fertile) from four different Italian hospitals were enrolled, partially retrospectively and partial longitudinally. Physical examination, clinical history (including presenting symptoms and triggering stress factors), laboratory and ECG findings and Doppler echocardiography were collected at hospital admission. Echocardiography was repeated at discharge (after at least seven days from admission).Results: No significant differences were observed considering trigger events or symptoms at presentation. Significant differences were observed considering left ventricle ejection fraction (LVEF) (37.9 ± 14.4% in fertile women, 43.9 ± 9.7% in postmenopausal women, p = .033) and regional wall motion abnormalities. The apical ballooning pattern was predominant in postmenopausal women, instead the midventricular type was mainly observed in fertile women (36% versus 1% in fertile versus postmenopausal women respectively, p < .001).Conclusions: Echocardiographic involvement of left ventricle is atypical in fertile women compared to women in menopause (midventricular versus apical ballooning, respectively). Moreover, the young group presented with worse LVEF but they had the same LV function at discharge and similar prognosis.
