摘　　要：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。Thirty-one normal adults and 41 patients of coronary artery diseases (CAD) with or without myocardial infarction were studied. Left systolic function was assessed by P-Doppler measurement of aortic valve annulus blood velocity (Ⅴ), maximal acceleration (AC), systolic velocity integration (Ⅵ) and cardiac output index (CI). The study showed that these paramsters were significantly different between patients with and without myocardial lnfarction. CI and AC values in patients with serious CAD were less sensitive than those in normal subjects. Ⅴ and Ⅵ however did not show significant difference among all patients.
