PHTN: pulmonary artery hypertension, RV: right ventricle, antegrade wave during systole (S-wave), retrograde wave in late systole (V-wave), antegrade wave in early-mid diastole (D-wave), and retrograde wave in late diastole (A-wave)., BSA: body surface area, m: meter, s: second,
ǂ Median and interquartile range (IQR) were presented for non-parametric variables and the Kruskal-Wallis test was used for comparison. Comparison between two groups were performed using the Mann-Whitney test.
† Mean and standard deviation were presented for normally distribute variables and one-way analysis of variance (ANOVA) was used for the comparison. The Bonferroni test was used as post hoc test.
