ABSTRACT
OBJECTIVE:
To assess differences in cardiac morphology and function at midgestation in fetuses from pregnancies that subsequently developed preeclampsia (PE) or gestational hypertension (GH).METHODS:
This was a prospective study in 5,801 women with singleton pregnancies attending for a routine ultrasound examination at midgestation, including 179 (3.1%) who subsequently developed PE and 149 (2.6%) who developed GH. Conventional and more advanced echocardiographic modalities, such as speckle-tracking, were used to assess fetal cardiac function in the right and left ventricle. The morphology of the fetal heart was assessed by calculating the right and left sphericity index.RESULTS:
In fetuses from the PE group (vs the no PE or GH group) there was a significantly higher left ventricular global longitudinal strain and lower left ventricular ejection fraction that could not be accounted for by fetal size. All other indices of fetal cardiac morphology and function were comparable between groups. There was no significant correlation between fetal cardiac indices and uterine artery pulsatility index multiple of the median or placental growth factor multiple of the median.CONCLUSION:
At midgestation, fetuses of mothers at risk of developing PE, but not those at risk of GH, have mild reduction in left ventricular myocardial function. Although absolute differences were minimal and most likely not clinically relevant, these may suggest an early programming effect on left ventricular contractility in fetuses of mothers who develop PE.Palavras-chave
