| 目的应用超声心动图分析正常孕妇不同孕期右心结构及功能参数的变化。 方法选取本院124例正常单胎孕妇,按不同孕期分为早孕组(64例)、中孕组(33例)和晚孕组(27例),另选取健康非妊娠妇女40例为对照组(n＝40)。比较各组一般资料、超声心动图的右心形态结构及心功能参数。 结果各孕期组孕妇与对照组体质量、体质指数、体表面积、心率、右心房横径、右心房长径、右心室舒张末面积、右心室收缩末面积、三尖瓣侧壁瓣环收缩期速度、三尖瓣舒张早期血流峰值速度与舒张晚期血流峰值速度的比值、三尖瓣侧壁瓣环舒张早期与晚期速度比值比较,差异有显著性(P＜0.05)；且随着妊娠月份的增加而变化(P＜0.05)。 结论正常单胎孕妇随着孕期的增加,右心结构及功能参数均发生变化,可能与其孕期心脏前后负荷增加有关。 |

| AimTo analyze changes in right heart structure and functional parameters during different trimesters of pregnancy in normal pregnant women by using echocardiography. MethodsTotally 124 normal singleton pregnant women were selected from our hospital and divided into early pregnancy group (64 cases), mid pregnancy group (33 cases), and late pregnancy group (27 cases) according to different pregnancy stages. Additionally, 40 healthy non-pregnant women were selected as the control group (n＝40). General information, right heart morphological structures, and cardiac functional parameters obtained from echocardiography were compared among the groups. ResultsThere were significant differences in body weight, body mass index, body surface area, heart rate, right atrial minor-axis diameter, right atrial long-axis diameter, right ventricular end-diastolic area, right ventricular end-systolic area, tricuspid lateral annular systolic velocity, the ratio of peak early diastolic tricuspid inflow velocity to peak late diastolic tricuspid inflow velocity, the ratio of early diastolic velocity to late diastolic velocity at the tricuspid lateral annulus, between pregnant women in each pregnancy group and the control group (P＜0.05). Additionally, these parameters changed with the increase of gestational months (P＜0.05). ConclusionNormal singleton pregnant women experience changes in right heart structure and functional parameters as pregnancy progresses, which may be related to the increase of preload and afterload on the maternal heart during pregnancy. |
