以Ｓｗａｎｇ一Ｇａｎｚ心导管对照，对３１例慢性阻塞性肺病（ＣＯＰＤ）用５种无创方法的５３项定量指标与肺动脉平均压（ＰＡＭＰ）进行了多因素相关分析及逐步回归分析，建立了由肺功能（ＲＦ）心脏Ｂ超（２－ＤＥ），肺血流图（ＩＰＧ）和心电图（ＥＣＧ）指标组成的予测ＰＡＭＰ的单独和联合手段的方程式。而后者的复相关系数公式估计误差明显优于单一手段方程式、显示出联合的优越性。本文认为对早期肺动脉高压（ＰＡＨ）诊断采取优化指标的联合定量实属必要。
Using Swang-Ganz cardiac catheterization, 53 quantitative indexes and PAMP of 31 patients with chronic obstructive pulmonary disease (COPD) by noninvasive method were analyzed by multivariate correlation analysis and stepwise regression analysis. Functional (RF) cardiac B-ultrasound (2-DE), pulmonary blood flow diagram (IPG) and electrocardiogram (ECG) The estimation error of the complex correlation coefficient formula of the latter is obviously better than that of the single means equation, which shows the superiority of the combination. This paper argues that it is necessary to take joint quantification of optimal indexes for the diagnosis of early pulmonary hypertension (PAH).
