In 192 patients with silicosis the results of the cardiac micro-catheterisation under conditions of rest were compared with those ones of a secondary examination performed two years later. This allows conclusions to the behaviour of the pressure values measured in the period observed as well as to the evidence of an individual cardiac micro-catheterisation. No essential increase of the mean pressure of the pulmonary artery was observed. The dispersion of an individual measurement is 3 Torr. A pulmonary hypertension, which is given from 20 Torr upwards, consequently may be established with a 95% statistical certainty only from an individual measuring value of 26 Torr.
对192例矽肺患者在静息状态下进行心脏微导管检查的结果与两年后进行的二次检查结果进行了比较。这有助于得出在观察期内所测压力值的变化情况以及个体心脏微导管检查的证据。未观察到肺动脉平均压力有实质性升高。单次测量的离散度为3托。因此，仅从26托的个体测量值，以95%的统计确定性才能确定存在20托及以上的肺动脉高压。
