2. Fig. 1
Receiver operator characteristic curves for estimating pulmonary capillary wedge pressure (PCWP) ≥15 mm Hg. Estimates were based on dichotomized variables based on their optimal cutoff. JVP, jugular venous pressure; BNP, B-type natriuretic peptide; E/E′, ratio of early mitral inflow to tissue velocity; IVCmax, maximum inferior vena cava diameter.

Proposed diagnostic scheme for estimating pulmonary capillary wedge pressure. ∗The test was negative or unable to be measured. JVP, jugular venous pressure; BNP, B-type natriuretic peptide; E/E′, ratio of early mitral inflow to tissue velocity; IVCmax, maximum inferior vena cava diameter.
