CI indicates cardiac index; CVP, central venous pressure; PAP, pulmonary artery pressure; PAWP, pulmonary artery wedge pressure; ReDS, remote dielectric sensing.

^a P<0.05, by linear regression analyses.

^b(V wave−PAWP) >7 mm Hg. Variables significant in the first multivariate analysis were enrolled into the second multivariate analysis.
