Abstract
- Background We sought to determine (1) long‐term outcomes in patients presenting with documented Takotsubo syndrome (TS), (2) whether left ventricular global longitudinal strain (LV‐GLS) provides incremental prognostic value, and (3) prognostic cutoffs of LV ejection fraction (LVEF) and LV‐GLS during an acute TS episode. Methods and Results We studied 650 patients with TS (aged 66±14 years, 88% women) who were diagnosed clinically and angiographically between 2006 and 2018. Baseline LVEF and LV‐GLS (using velocity vector imaging) were recorded. The primary end point was all‐cause mortality. TS triggers were unknown (34%), emotional (16%), physical (41%), and neurologic (10%). Mean LVEF and LV‐GLS were 36±10% and −11.6±0.4%; in addition, 94% patients had LVEF
