Gilewski W, et al. - This study intended to confirm the prognostic utility of selected echocardiographic (UKG), impedance cardiography (ICG), and right heart catheterization (RHC) parameters in systolic heart failure (HF). Findings suggested that composite measures based on non-invasive parameters, such as IVC%/tricuspid annular plane systolic excursion (TAPSE), RVSP/TAPSE and right atrial (RA) × inferior vena cava diameter on inspiration (IVCinsp)/S’RV may be as accurate as the invasive examination for prognosis assessment. The best individual predictors of the composite endpoint were pulmonary capillary wedge pressure (PCWP) and cardiac index (CI) determined during RHC. Additionally, echocardiographic parameters such as right ventricular dimension (RVD), RA, IVC, TAPSE, and S’RV accurately predicted unfavorable outcome.
