Transthoracic echocardiography measurements of the right and left ventricle function after polytrauma. A) Measurements of ejection faction (EF) in % at day 1 and day 2 after polytrauma in comparison to standard values (CI 54.22 to 72.73). B) left ventricular end-diastolic diameter (LVEDD) as additional parameter of the left ventricle function in comparison to standard measurement values (CI 32.95 to 62.05). C) Thickness of the interventricular septum and posterior wall of the left ventricle (IVS/LVPW) at both timepoints as parameter of left ventricle hypertrophy (CI 0.89 to 1.477). To evaluate the right ventricle function: D) The tricuspid annular plane systolic excursion (TAPSE) (CI 14.45 to 31.94), as well as E) the right ventricular end-diastolic diameter (RVEDD) (CI 19.09 to 31.17) and F) the systolic pulmonary artery pressure (sPAP) were compared with standard values (CI 10.83 to 51.65). Normal = standard values d1 = day 1, d2 = day 2, *p ≤ 0.05, **p ≤ 0.01
