| 目的 实时三维超声心动图(RT-3DE)定量评价慢性肾衰(CRF)与原发高血压(HTN)患者左室整体功能。方法 用二维及三维超声心动图依次检查慢性肾衰患者(CRF组)23例,高血压患者(HTN组)22例及正常对照组23例;采集二维及三维相关参数。结果 与正常对照组比较,CRF组3D-EF(三维的EF值)、PER(峰值射血率)及PFR(峰值充盈率)均降低(P<0.05), LVMI(左室质量指数)、ESV(收缩末期容积)、16Tmsv-SD(左室16-节段达峰时间标准差)、16Tmsv-Dif(左室16-节段达峰最大差值)升高(P<0.05)。与HTN间比较,CRF组3D-EF及PER降低,ESV、16Tmsv-SD、16Tmsv-Dif升高(P<0.05)。结论 CRF患者左室功能的损害较HTN患者更明显;RT-3DE超声心动图为评价CRF患者左室整体功能提供无创、有效的新方法。 |

| Objective To study the difference of the global function of left ventricle in patients with chronic renal failure (CRF) and primary hypertension (HTN) by real-time three-dimensional echocardiography (RT-3DE). Methods Twenty-three patients of CRF, 22 patients of HTN and 23 normal subjects were examined in this study by RT-3DE respectively. The global and regional volume-time curves were obtained. The left ventricular mass and function parameters, such as the peak ejection rate (PER), peak early filling rate (PFR) were derived. Results Compared with normal group, EF, PER and PFR of CRF group was significantly lower while 16Tmsv-SD,16Tmsv-Dif,LVMI and ESV of CRF group were significantly higher (P<0.05). Compared with HTN group, EF and PER were significantly lower while the 16Tmsv-SD, 16Tmsv-Dif and ESV were higher in the CRF group. Conclusion The left ventricular function of CRF group is lower than HTN group. RT-3DE is proven a feasible and accurate method for analysis of left ventricular function in patients with chronic renal failure. |
