摘要:

目的 评价妊娠高血压综合征(PIH) 患者分娩前后左室舒张功能变化。方法 临床诊断为重度PIH 患者32例, 正常妊娠(NP) 24 例。采用美国Acuson 128 XP/10 彩色电脑声像仪, 采用M 型超声心动图记录二尖瓣舒张早期活动情况, 测量E2F 斜率。多普勒超声心动图测量二尖瓣血流峰值速度(E,A ) 及速度时间积分, 计算E/A 比值及快速充盈分数(RFF)。产后2 个月内复查。结果 PIH 组同N P 组相比, 二尖瓣E2F 缓慢(6.4±2.9 vs 9.3±4. 5cm/s, P < 0. 05) , E/A 明显下降(1.2±0.2 vs 1.4±0.2, P < 0. 01) , RFF 减低(56% ±5% vs 60% ±5% , P < 0.05)。产后复查时, PIH 组E/A 明显升高(1.2±0.2 vs 1.5±0.3, P < 0. 01) , 接近正常产后水平(1.5±0.3 vs 1.6±0. , P > 0. 05) ; RFF, E2F 下降速度与正常产后无显著差别(P > 0. 05)。结论 重度PIH 患者孕晚期可出现左室舒张功能受损, 除个别病例外, 大多数患者产后2 个月内恢复正常。

Abstract:

AIM To evaluate left ventricular diastolic function in pregnancy-induced hypertension (PIH) patients before and after parturition.METHODS Thirty-two patients and 24 women with normal pregnancies (NP) were studied BY Acuson 128XP/10 computed sonography. The average gestational age for PIH patients was 38.3 wk and those for NP group were 39.1 wk. The E-F slope, peak velocity (E,A), E/A ratio and VTI of MV and rapid filling fraction(RFF) of the left ventricle were measured by M-mode and pulsed Doppler echocardiography. All pregnant women were to be reexamined in two months after delivery.RESULTS The E-F slope (6.4±2.9vs9.3 ±4.5 cm/s,P<0.05), RFF(56%±5%vs60%±5%,P<0.05) and E/A (1.2±0.2vs1.4± 0.2,P<0.01) of PIH patients were obviously reduced to compared with NP patients. E/A significantly increased after parturition (1.2±0.2vs1.5±0.3,P<0.01 ) in PIHand was closed to the level of NP postparturition( 1.5±0.3vs1.6±0.3,P>0.05). RFF and E-F slope were retured to the postparturition level of NP.CONCLUSION PIH patients may have left ventricular diastolic dysfunction in our group and most of them could be normal in two months after parturition.
