Description of the study: Takotsubo syndrome (TTS), also known as apical ballooning syndrome, Takotsubo cardiomyopathy, broken heart syndrome, and stress-induced cardiomyopathy, is a rare condition and accounts for 1–3% of all patients referred to hemodynamic laboratories with a primary diagnosis of acute coronary syndrome (ACS).
The primary objective of the study is to assess whether the use of levosimendan in TTS improves LVEF in TTE 72 ± 3 hours after the end of the levosimendan infusion (primary primary endpoint). linical benefit will be defined as a reduction in the incidence of adverse major cardiovascular events such as all-cause death, TTS recurrence or worsening heart failure leading to unscheduled hospitalization, stroke or TIA (major secondary endpoint) over the 12-month follow-up period.
