Changes in hemodynamic parameters over 14 days in 46 subarachnoid hemorrhage patients with Takotsubo cardiomyopathy. Cardiac function index (CFI) (A), cardiac index (CI) (B), global end-diastolic volume index (GEDI) (C) and extravascular lung water index (ELWI) (D) in patients with (●) or without (○) left ventricular (LV) dysfunction. Data were obtained from a total of 1,330 PiCCO™ measurements. Averaged data collected every 12 hours (twice a day) are presented. *P < 0.05 for left ventricular ejection fraction (LVEF) ≥40% versus LVEF <40% at the same time point. SAH: Subarachnoid hemorrhage.
