目的 研究妊娠合并糖尿病及妊娠期糖尿病 (妊娠糖尿病 )孕妇胎儿心脏形态和功能的变化。方法 应用超声诊断仪测定 2 3例妊娠糖尿病孕妇妊娠的胎儿 (研究组 )和 10 8例正常孕妇妊娠的胎儿 (对照组 )的心脏室间隔厚度、心室收缩期及舒张期周长和面积、心室收缩分数 1[(心室舒张期周长 -心室收缩期周长 ) /心室舒张期周长 ]、心室收缩分数 2 [(心室舒张期面积 -心室收缩期面积 ) /心室舒张期面积 ]。并随访两组新生儿出生体重。结果 研究组室间隔厚度为 [( 6 1± 0 7)mm , x±s,下同 ]明显高于对照组 ( 4 4± 0 7)mm。研究组左心室舒张期、收缩期面积分别为 ( 3 3± 0 8)cm2 、( 2 2± 0 6)cm2 ,明显高于对照组的 ( 2 6± 0 6)cm2 、( 2 0± 0 5)cm2 。研究组右心室舒张期面积、收缩期面积分别为 ( 3 9± 0 7)cm2 、( 2 6± 0 7)cm2 ,明显高于对照组的 ( 3 5± 0 5)cm2 、( 2 4± 0 7)cm2 。研究组左心室收缩分数 1为 0 2 0± 0 0 7,明显大于对照组的 0 12± 0 0 4。研究组左心室收缩分数 2为 0 35± 0 11,明显高于对照组的 0 2 3± 0 10。研究组右心室收缩分数 1( 0 19± 0 0 5)明显高于对照组 ( 0 13± 0 11)。研究组右心室收缩分数 2 ( 0 3 3± 0 0 9)明显高于对照组 (
Objective To study the changes of fetal heart morphology and function in pregnant women with gestational diabetes mellitus and gestational diabetes mellitus (gestational diabetes mellitus). Methods The thickness of ventricular septum, the ventricular systolic and diastolic circumference and area, the ventricular volume and heart rate were measured by using the ultrasonic diagnostic apparatus in fetuses (study group) of 23 pregnant women with gestational diabetes mellitus and in the fetus of 108 pregnant women with normal pregnancy (control group) Systolic score 1 [(ventricular diastolic perimeter - ventricular systolic perimeter) / ventricular diastolic perimeter], ventricular systolic fraction 2 [(ventricular diastolic area - ventricular systolic area) / ventricular diastolic area]. Two groups of newborns were followed up for birth weight. Results The thickness of the interventricular septum in the study group was significantly higher than that in the control group [(61 ± 0 7) mm, x ± s, the same below] (44 ± 0 7) mm. The left ventricular diastolic and systolic areas in the study group were (3 3 ± 0 8) cm2 and (2 2 ± 0 6) cm2, respectively, which were significantly higher than those of the control group (2 6 ± 0 6) cm2 and 5) cm2. The diastolic area and systolic area of the right ventricle in the study group were (39 ± 0 7) cm2 and (26 ± 0 7) cm2, respectively, which were significantly higher than those in the control group (3 5 ± 0 5) cm2 and 0 7) cm2. Study group left ventricular systolic fraction 1 was 0 2 0 ± 0 0 7, significantly greater than the control group 0 12 ± 0 0 4. The left ventricular systolic score 2 in the study group was 0 35 ± 0 11, which was significantly higher than that of the control group 0 2 3 ± 0 10. The right ventricular systolic fraction 1 (0 19 ± 0 0 5) in the study group was significantly higher than that in the control group (0 13 ± 0 11). Study group, right ventricular systolic score 2 (0 3 3 ± 0 0 9) was significantly higher than the control group (
