    AbstractWe assessed the hypothesis that non-invasive measurement of stroke volume index can replace invasive measurements in patients with chronic heart failure. Non-invasive impedance cardiography (ICG) measurements together with invasive hemodynamic thermodilution (TD) measurements were performed in 13 patients with severe chronic heart failure (NYHA III-IV). Agreement between ICG and TD regarding stroke volume index was poor. Correlation between non-invasive and invasive hemodynamic measurements was low (r=0.29). In conclusion, non-invasive measurements of stroke volume index using impedance cardiography did not result in sufficient agreement with invasive thermodilution measurements in this study with patients suffering from severe chronic heart failure.Copyright (c) 2008 Elsevier Ireland Ltd.
