To examine left ventricular function in pregnancy complicated by preeclampsia, echocardiographic dimensions and left ventricular performance indices were determined in 42 preeclamptic patients, 25 normotensive third-trimester patients, and 25 nonpregnant patients. The performance of the left ventricle in normal third-trimester pregnant patients was unchanged as compared to that in nonpregnant patients. Three patients (7%) in the preeclamptic group had diminished values of echocardiographic contractility indices. However, in only one of these patients were there clinical signs of left heart failure; two other patients had latent myocardial dysfunction. Our conclusion is that left ventricular function in most preeclamptic patients is well preserved despite significant volume and pressure overload.
为研究妊娠合并子痫前期患者的左心室功能，对42例子痫前期患者、25例孕晚期血压正常的患者及25例非妊娠患者进行了超声心动图测量及左心室功能指标测定。与非妊娠患者相比，正常孕晚期妊娠患者的左心室功能无变化。子痫前期组中有3例患者（7%）超声心动图收缩功能指标值降低。然而，这些患者中只有1例有左心衰竭的临床体征；另外2例有潜在心肌功能障碍。我们的结论是，尽管存在明显的容量和压力超负荷，但大多数子痫前期患者的左心室功能仍保持良好。
