Fig. 5. Receiving operating characteristic curves assessing the ability of Doppler tissue imaging and color M-mode Doppler for predicting a pulmonary capillary wedge pressure (PCWP) of 13 mmHg or greater or 8 mmHg or less in the test population. (Left ) Receiving operating characteristic curve assessing the ability of E/Ea and E/Vp for predicting a PCWP of 13 mmHg or greater. Areas under the curve (AUC) were, respectively, 0.97 for E/Ea and 0.83 for E/Vp. The numbers in bracket indicate the value of the cutoff. (Right ) Receiving operating characteristic curve assessing the ability of E/Ea and E/Vp for predicting a PCWP of 8 mmHg or less. AUCs were, respectively, 0.80 for E/Ea and 0.67 for E/Vp. The numbers in bracket indicate the value of the cutoff.
