| 目的 应用瞬时波强(WI)技术检测慢性肾衰竭(CRF)与原发性高血压(HTN)患者颈动脉弹性功能。 方法 用WI技术依次检查CRF组患者30例、HTN组患者30例及正常对照组35名;采集WI相关参数W2、NA、β、Ep、PWVβ、瞬时减速度波强(W2)、瞬时波强负向波面积(NA)、僵硬度(β)、压力应变弹性模量(Ep)、单点脉搏波传导速度(PWVβ)、WI脉搏波传导速度(PWVWI)、顺应性(AC)、脉搏波反射增强(AI)。结果 与正常对照组比较,CRF组W2、NA、β、Ep、PWVβ、PWVWI明显增高(P<0.05),AC、AI无明显差异(P>0.05);HTN组β、Ep、PWVβ、PWVWI明显增高(P<0.05),W2、NA、AC、AI差异无统计学意义(P>0.05)。与HTN组比较,CRF组W2、NA、β、Ep、PWVβ、PWVWI明显增高(P<0.05),AC、AI差异无统计学意义(P>0.05)。CRF患者血肌酐水平、患病年限与W2、NA、β、Ep、PWVβ、PWVWI均存在不同程度的正相关。结论 应用WI技术能反映动脉早期血管壁弹性的变化。 |

| Objective To evaluate the carotid elasticity quantitatively in patients with chronic renal failure (CRF) and primary hypertension (HTN) with wave intensity (WI) technique. Methods Thirty patients with CRF, 30 patients with HTN and 35 normal subjects were examined respectively with WI technique. Transient deceleration wave intensity (W2), negative area (NA), stiffness parameter (β), strain elastic modulus (Ep), one-point pulse wave velocity (PWVβ and PWVWI), arterial compliance (AC) and argumentation index (AI) were calculated. Results Compared with both HTN and normal subjects, W2, NA, β, Ep, PWVβ, PWVWI were higher in CRF patients (P<0.05), whereas no significant difference of AI, and AC were found among normal control, CRF or HTN patients (P>0.05). Compared with normal subjects, β, Ep, PWVβ, PWVWI were also higher in HTN patients. Serum levels of blood urea nitrogen and duration were positively related to the W2, NA, β, Ep, PWVβ, PWVWI. Conclusion WI can be used to evaluate the arterial elasticity of the patients with CRF. |
