Table 4 Left atrial function in Takotsubo syndrome patients with impaired and already recovered left ventricular function

From: Transient left atrial dysfunction is a feature of Takotsubo syndrome

Variable LV ejection fraction <55% (n = 95) LV ejection fraction ≥55% (n = 29) p
Total LA-EF (global function; reservoir) 42 (30–52) 51 (42–59) <0.01
Passive LA-EF (conduit)a 19 (14–29) 25 (20–35) <0.01
Active LA-EF (booster pump)a 28 (16–38) 30 (24–39) 0.12
  1. Values are median (IQR)
  2. EF emptying fraction, LA left atrial, LV left ventricular
  3. aPatients with atrial fibrillation during CMR imaging (n = 8) were excluded from this analysis, resulting in 89 patients with reduced and 27 patients with recovered LV ejection fraction
  4. P-values in bold type indicate a significant difference between groups
