| 目的 应用血管回声跟踪技术评价脑梗死患者颈动脉弹性的变化。 方法 应用血管回声跟踪技术检测135例脑梗死患者颈动脉弹性功能改变,并与70例正常人(对照Ⅰ组)及70例颈动脉有斑块形成的非脑梗死患者(对照Ⅱ组)相对照。 结果 脑梗死组β、Ep、AI及PWVβ较对照Ⅰ组升高,但AC较对照Ⅰ组降低,且差异有统计学意义;脑梗死组β、Ep、AI及PWVβ较对照Ⅱ组升高,AC较对照Ⅱ组稍降低,两组β、Ep及PWVβ差异有统计学意义,AC及AI差异无统计学意义。颈动脉弹性指标Ep、β、AI及PWVβ的RR值大于1,其中PWVβ的RR值最大。 结论 ET技术可较为敏感地反映出脑梗死患者颈动脉弹性的降低。 |

| Objective To investigate the changes of the elasticity of carotid artery in patients with cerebral infarction with echo-tracking (ET) technique. Methods A total of 135 patients with cerebral infarction, 70 healthy subjects as normal control group (groupⅠ) and 70 patients with plaques in the carotid artery but without cerebral infarction (groupⅡ) were studied with echo-tracking technique. The elasticity modulus (Ep), artery compliance (AC), artery stiffness (β), one-point pulse wave velocity (PWVβ) and augmentation index (AI) were individually measured. Results Ep, β, PWVβ and AI of the cerebral infarction group were higher, but the AC was lower than that of groupⅠ(P<0.01). Ep, β, PWVβ and AI of the cerebral infarction group were higher than those of groupⅡ, but AC was slightly lower than that of groupⅡ. The difference of Ep, β and PWVβ between two groups were statistically significant, while of AC and AI were not. According to the Logistic study in the cerebral infarction group, RR of Ep was 1.019, of β was 1.229, of AI, PWVβ and AC were 1.028, 1.857 and 0.986, respectively. Conclusion The elasticity degrading of the carotid artery can be detected sensitively with ET technique. |
