摘要
本研究旨在探讨多普勒超声心动图无创估测闭塞性肺血管病肺动脉高压的价值。通过对19例闭塞性肺血管病患者进行多普勒超声检查,并与48小时内进行的右心导管检查资料做对比分析。结果提示,压差法能够直接准确测定肺动脉收缩压(SPAP),但仅限于存在三尖瓣反流的患者;血流加速度时间(ACT)、血流加速度时间/右室射血时间(ACT/RVET)和右室射血前期/血流加速度时间(RPEP/ACT)能够定量估测肺动脉高压,但明显受心脏指数(CI)的影响。
The purpose of this study was to explore the value of noninvssive estimstion of pulmonary hypertension in obliterativa pulmonar), vascular disease (OPYD) with Doppler echocardiography. Continued and pulsed wave Doppler echocardiography and right heart catheterization were per formed within 48 hours in 19 patients with OPVD. It is concluded that SPAP can be precisely predicted with continued wave Doppler ultrasound only in patients with tricuspid regurgitation, while pulsed wave Doppler echocardiography can be used for most patients. Doppler indexes ACT, ACT/BVET and BPEP/ACT could quantitatively estimate PAP. The influence of Cl on Doppler predictors must be taken into consideration.
