本文依据56例慢性阻塞性肺病和肺心病人的右心导管资料,分析了右心收缩时间间期(RSTI)指标RICT、RPEP、RVET、RPEP/RVET与右心舒缩能中dp/dtmax、t-dp/dtmax,VCE_(10)、Vmax,-dp/dtmax诸参数的关系,结果显示了二者之间有一定的相关性。还探讨了使用无创性方法可以检测的RSTI来定量反映不易广泛开展的右心舒缩性能指标的可行性。用多元逐步回归分析方法建立了五个计算右心舒缩性能指标的方程式,经F检验,其dp/dtmax、t-dp/dtmax、-dp/dtmax三个方程式有显著意义(P<0.05)。
Based on the data of right heart catheterization in 56 patients with chronic obstructive pulmonary disease and pulmonary heart disease, we analyzed the relationship between RICT, RPEP, RVET, RPEP / RVET and dp / dtmax in right ventricular systolic and diastolic function, t-dp / dtmax, VCE_ (10), Vmax, -dp / dtmax parameters, the results show that there is a certain correlation between the two. We also explored the feasibility of using a noninvasive method to detect RSTI to quantify the performance of right-sided systolic and diastolic parameters that are not easily available. Five regression equations of right ventricular systolic and diastolic function were established by multivariate stepwise regression analysis. The three equations of dp / dtmax, t-dp / dtmax and -dp / dtmax were significant (P <0.05) .
