Long-term outcome in patients with Takotsubo syndrome presenting with severely reduced left ventricular ejection fraction

Aim: To evaluate the long-term outcome of patients with Takotsubo syndrome (TTS) and severely reduced left ventricular ejection fraction (LVEF ≤ 35%) at presentation. Methods and results: The study population included 326 patients (mean age 69.5 ± 10.7 years, 28 male) with TTS enrolled in the Takotsubo Italian Network, divided into two groups according to LVEF (≤ 35%, n = 131; > 35%, n = 195), as assessed by transthoracic echocardiography at hospital admission. In-hospital events were recorded in both groups. At long-term follow-up (median 26.5 months, interquartile range 18–33), composite major adverse cardiac events (MACE: cardiac death, acute myocardial infarction, heart failure, and …
