摘要
本文报道了应用超声心动图面积－长度法评价１５例闭塞性肺血管病右心功能及吸入一氧化氮（ＮＯ）后右心功能的变化。结果表明右室舒张末期容积（ＲＶＥＤＶ）和收缩末期容积（ＲＶＥＳＶ）增加，右室每搏量（ＲＶＳＶ）、右室射血分数（ＲＶＥＦ）和右心排血量（ＲＶＣＯ）均降低。吸入ＮＯ后收缩期跨三尖瓣峰值压差平均降低２３％（Ｐ＜０．００１），ＲＶＥＤＶ和ＲＶＥＳＶ分别减小１７．７％和３７．４（Ｐ值均小于０．００１），ＲＶＳＶ、ＲＶＥＦ、ＲＶＣＯ分别增加３０．８％、５８．７％、３４．４％（Ｐ值均小于０．０１－０．００１），提示右心功能有明显改善。
To evaluate right ventricular function in patients with obliterative pulmonary vascular diseases and effect of inhaled nitric oxide,fifteen cases of obliterative pulmonary vascular diseases were studied with echocardiographic method of the area-length,including eight patients with primary pulmonary hypertension and seven patients with pulmonary embolism. Results showed right ventricular end diastolic volume (RVEDV)and end systolic volume(RVESV)were increased.Stroke volume,ejection fraction,cardiac output of the right ventricle(RVSV,RVEF,RVCO)were all decrased. After inhaled nitric oxide,systolic mean peak pressure gradient across tricuspid valves was decreased 23%.RVEDV and RVESV were decrease 17%(P<0.001)and 37.4%(P<0.001),separatively;RVSV,RVEF and RVCO were increased 30.8%,58.7%and 34.4%(P<0. 01-0.001),separatively.It indicated that the function of the right heart was improvedapparently.
