The results showed that the best correlations with pulmonary arterial systolic and mean pressure (PASP.PAMP) were obtained by the EPA/FAO(r = 0. 84,0. 81) ,the ACC correlated well with PASP, PASP(r = 0. 72,0. 65),the correlations between PEP/AT and PASP.

• 结果显示:肺动脉/主动脉血流时间间期比与右心导管估测的肺动脉收缩压(PASP)、平均压(PAMP)取得了较好的相关性(r分别为0.；84、0
