N2 - Routine cardiac catheterization to assess pulmonary capillary wedge pressure (PCWP) is not recommended in heart failure (HF), and various noninvasive tools have been proposed. The authors evaluated the reliability of echocardiography, brain natriuretic peptide (BNP), and thoracic electrical bioimpedance (TEB) in predicting PCWP in 29 patients (72±4years, New York Heart Association class 3.5±0.9, ejection fraction 28%±6%) who underwent hemodynamic evaluation for worsening HF. Echocardiography was performed immediately before the hemodynamic study. During clinical stability, PCWP, plasma BNP, and TEB were simultaneously assessed. Among TEB variables, thoracic conductance (thoracic fluid content [TFC]=1/kΩ) was used. PCWP was related with E/E′ obtained with mitral Doppler and mitral annulus tissue Doppler imaging echocardiography (R=0.55, P
