Echocardiographic hemodynamic and left ventricular parameters were determined in 14 normotensive and 18 hypertensive women during the last trimester of pregnancy. The hypertensive patients had significantly higher mean values of total peripheral resistance (p less than 0.001), maximum velocity of posterior wall motion (p less than 0.05), mean velocity of circumferential fiber shortening (p less than 0.01) and percent fiber shortening of left ventricular diameter (p less than 0.05). The mean values for heart rate, stroke volume, cardiac output, cardiac index, left ventricular posterior wall thickness and septal thickness did not differ significantly in both groups. These results reflect increased cardiac contractility related to elevated peripheral vascular resistance in subjects with pregnancy-induced hypertension.
在妊娠晚期,对14名血压正常和18名高血压女性进行了超声心动图血流动力学和左心室参数测定。高血压患者的总外周阻力平均值显著更高(p<0.001)、后壁运动最大速度(p<0.05)、圆周纤维缩短平均速度(p<0.01)和左心室直径纤维缩短百分比(p<0.05)。两组的心率、每搏输出量、心输出量、心脏指数、左心室后壁厚度和室间隔厚度平均值无显著差异。这些结果反映了妊娠高血压患者心脏收缩力增加与外周血管阻力升高有关。
