应用P-Doppler UCG检测31例正常人及41例经冠脉造影证实的冠心病人,定量分析主动脉根部主要的收缩期参数。结果显示:CI、AC、VI及V四项参数在心肌梗塞与非梗塞组之间差异均有显著或非常显著性(P<0.05或<0.01)。CI和AC在正常与严重冠心病各组之间差异有显著或非常显著性(P<0.05或0.01)。AC在轻度与极重度冠心病者间差异有显著性(P<0.05)。而V和VI在正常与不同严重度冠心病各组间差异均无显著性(P>0.05)。表明P-Doppler收缩功能分析在一定程度上尚能反映冠脉病变的程度和左室的收缩功能状态。
P-Doppler UCG detection of 31 cases of normal subjects and 41 cases of coronary heart disease confirmed by coronary angiography, quantitative analysis of aortic root systolic parameters. The results showed that the four parameters of CI, AC, VI and V were significantly or very significantly different between myocardial infarction group and non-infarction group (P <0.05 or <0.01). CI and AC in normal and severe coronary heart disease group differences were significant or very significant (P <0.05 or 0.01). AC in mild and severe coronary heart disease were significantly different (P <0.05). However, there was no significant difference between V and VI in each group of coronary heart disease with normal and different severity (P> 0.05). P-Doppler systolic function analysis to some extent still reflect the extent of coronary lesions and left ventricular systolic function status.
