E, peak early diastolic transmitral flow velocity; e′, peak early diastolic mean mitral annular velocity; ePAWP, estimated pulmonary arterial wedge pressure; IVC, inferior vena cava; LAD, left atrial diameter; LVDd, left ventricular end‐diastolic diameter; LVEF, left ventricular ejection fraction; MR, mitral regurgitation; RVDd, right ventricular end‐diastolic diameter; TR, tricuspid regurgitation; TRPG, tricuspid regurgitation pressure gradient.
Values are shown as median (interquartile range) unless otherwise indicated. For multiple comparisons, analysis of variance was used for symmetrical continuous variables, the Kruskal–Wallis test was used for asymmetric continuous variables, and the χ 2 test was used for categorical variables. All pairwise comparisons were performed with the Tukey–Kramer test for symmetrical continuous variables, the Steel–Dwass test for asymmetric continuous variables, and the χ 2 test with Bonferroni correction for categorical variables.
P < 0.05 vs. first tertile group.
P < 0.05 vs. second tertile group.
