摘要
本文应用超声心动图测定了２３例妊娠高血压症，２０例晚期妊娠和２０例正常妇女左室功能和血液动力学变化，并进行了比较。结果表明：妊娠高血压是由于妊娠所致的血容量增高导致的容量性高血压，其主要特点是：心输出量增加，外周阻力降低，未发现潜在的心功能不全。
Changes of left ventricular fuuction and hemodynamics were studied in 63 female subjects using echocardiograpby. These subjects were divided into three groups: Group 1, 20 healthy nonpregnant women; Group 2,20 normotensive late pregnant women; and Group 3,23 women with pregnancy-induced hypertension. The results showed that the hypertensive pregnant women had significantly higher HR, SV and EF than those of nomnal controls(P<0.01). LVM, LVPWS,FS,Dd,REFLV,RFDD,SFDd and PWTd were more markedly increased in hypertensive pregnant women than those in normal controls.Significant inverse correlation was found between increased CO and lowered SVR(r=-0.96)inhypertensive pregnant women.In comparison with normotensive women with latePregnancy,CO and SV increased by 26.3% and 22.1%respectively,EF and LVM were significantly increased(P<0.01) and SVR significantly lowered in hypertensive pregnant women. In conclusion, hypertension of pregnancy was volume Over-loaded hypertension causcd by pregnancy,characterized by a marked increase in CO and a noticeable decline in SVR,However,potential cardiac dysfunction was not found.
